Troubleshooting

• Troubleshooting Tips

Power-On Self-Test

The OmniBook 800 BIOS includes a Power-On Self-Test (POST) facility that tests a number of hardware and firmware items in the unit at each cold-start (BOOT or RESET).

The OmniBook self-test alone should not be used to diagnose a hardware problem. If the selftest results are absolutely clear and repeatable, confirm the results with at least two other nonself-test failure symptoms.

Within POST, there are three kinds of messages:

• Error Messages – These messages appear when there is a failure in hardware, software, or firmware.

• Informational Messages – These messages provide information to the user but require no action.

• Beep Codes – This kind of warning sounds when POST errors occur and the screen is not yet available.

Beep Codes

These multiple beep codes indicate a failure in a simple test of:

• a portion of base memory

• flash BIOS checksum

• a portion of conventional memory

• a portion of extended memory

If the unit fails to boot, ensure that

• all accessories are removed, including: memory, floppy drive, docking station, modems and other PC Cards, printers, external displays, pointing devices, and keyboard

• clean AC power is provided (no “chained” battery chargers or auto adapters), and press reset.

If the unit still fails to boot, it requires service. Beep codes are used to identify a POST error that occurs when the screen is not available.

Once the screen is operating, diagnostic messages are reported to the screen. There are beep codes for both fatal and non-fatal system board errors.

Table 2 - POST Beep Codes

Beep Code Description S-S-S-P-S-S-L-P The DMA page registers are faulty. S-S-S-P-S-L-S-P The refresh circuitry is faulty S-S-S-P-S-L-L-P The ROM checksum is incorrect S-S-S-P-L-S-S-P The CMOS RAM test failed S-S-S-P-L-S-L-P The DMA controller is faulty S-S-S-P-L-L-S-P The interrupt controller failed S-S-S-P-L-L-L-P The 8042 keyboard controller failed S-S-L-P-S-S-S-P No video adapter was found S-S-L-P-S-S-L-P No RAM installed. No message is displayed.

Display Codes

There are a number of Power On Self Test (POST) tests that are performed after the Beep Code tests. Failure of one or more of these tests will result in a displayed failure code (such as

03044). It is extremely important not to interpret a failure code immediately as a hardware failure. The failure should be confirmed with a clean boot. A clean boot is defined as pressing the reset button after removing all accessories (including additional memory, floppy drive, modems, PC cards, and printers) and providing a reliable power source. Note, make sure the display is adjusted to be visible.

The following tables lists common PC error messages. Not all of these messages will appear on every model of the OmniBook 800.

OmniBook Diagnostics

The OmniBook diagnostics program provides an effective tool for diagnosing and isolating a hardware problem. The diagnostics software is intended for use in concert with additional troubleshooting methods to accurately determine the cause of trouble. The diagnostics program is not designed for unassisted end customer use.

Diag is a DOS program developed to test the OmniBook 800 computer and docking station. For the most part Diag is a stand-alone program, testing components and subsystems independently. Some tests require “loopback” adapters for complete testing, and some tests require other hardware (e.g. SCSI devices). Basic knowledge of running software is assumed.

Running the diagnostics program

A “clean boot” is the environment from which to run Diag. For a system that normally boots up to Windows for Workgroups, press F5 at bootup. For a Windows 95 system, press Shift+F5. Alternatively, the CONFIG.SYS and AUTOEXEC.BAT files may be modified to exclude drivers and/or launch Diag if desired. Please note that the SCSI tests do require loading some drivers; those drivers will be addressed in the context of those tests.

The diagnostic program is located in the c:\omnibook\diag directory and is invoked by typing

diag followed by the Enter key.

Main diagnostic screen

The OmniBook diagnostic program is controlled primarily from a single screen. The top two thirds of the screen reports the tests selected and test results. The bottom third is used to scroll test results as the tests run. Thirty tests are listed under the Menu heading. See Figure 4 for a sample of the main diagnostic screen.

Tests selected for looped running show a test level of 1 to 3 to the left of the test name. When a test ends, the status of the test and the date and time are reported. As a test runs, ongoing status can be reported either on the same line as the test, or scrolled into the bottom region. When looping tests are performed, the bottom line reports when the loops begun and which loop is currently running. If a test ever fails, a red ‘x’ appears to the left of the test name. The version of Diag is reported near the bottom of the display, as is the version of the BIOS. External monitor colors can be checked at a glance with the RED GREEN and BLUE colored text boxes.

Figure 4 - Main Diagnostic Screen

Running selected tests

Tests may be initiated individually, or as a group. Some tests may be run at different levels. In general, tests that can take a long time to be fully checked have levels that permit testing more quickly while still providing a reasonable level of testing. An unselected test has a <Space> before the test name. A test at a quick level has a <1> before the test name. A standard level test has a <2> before the test name. A long test has a <3> before the test name. Every test has a standard level. Some tests also have a quick level, and some tests also have a long level. Some have both quick and long.

The name of the currently selected test is always shown inversed. To help monitor the progress of testing, the LEDs (near the On button) blink about once per

second from green to off. If a test has failed the LEDs blink from red to off. When Diag finishes testing, the LEDs blink rapidly. If the system locks up for some reason, the LEDs generally stop blinking.

Alternative methods for running tests

Individual tests may be run by moving the highlight to the desired test and running it. Move the highlight and run the tests by the following means:

Keyboard – cursor <Up> and <Down> keys to select, <Enter> to run. Also <Space> to specify a test level, <Backspace> to cancel a test, <Esc> to exit Diag. Many other features and options are also available from the keyboard.

Contrast/Brightness buttons – <Down> to select (mimics the Down key), <Up> to run (mimics the Enter key). This is most useful on production units that have no keyboard. For checking “Newton rings” during display testing, it is necessary to adjust the contrast. To have the contrast keys operate normally, press both at once. To have them mimic the Down and Enter keys, press both again.

Mouse – when the -m command line option is specified, use the top or bottom “bumper” to select, and left button to run. Also use the right button to specify test level (space), right bumper to cancel a test (Backspace), and left bumper to exit Diag (Esc).

Serial – same keys as with a keyboard, but from a remote system (HP 100LX, etc) connected into the RS232 port on the OmniBook. The remote computer’s serial port should be configured for 9600,N,8,1. The communication program Kermit is well suited to communicate with Diag, in that it sends cursor and function key codes as PC key codes (e.g. <Up> transmits <NULL> then <;>). Controlling Diag via the serial port permits the same level of control of modes and toggles as does direct keyboard control. Please note that the serial test cannot be run when the serial port is used for control (though the serial port gets a decent workout controlling Diag anyway).

Special test hardware requirements

The following tests require the following hardware to operate:

• The Upper/Lower PC Card tests require a Sycard test card and a modified extender card.

• The IR port test requires another OmniBook 800 running the fast IR test.

• The Serial port test requires an HP RS-232 serial loop back connector.

• The Printer port test requires an HP parallel port loop back connector.

• The SCSI test requires an HP SCSI port loop back connector.

• The SCSI CD ROM test requires a CD ROM device connected by SCSI cable.

• The SCSI Hard disk test requires a Hard disk connected by SCSI cable.

• The Dock slots test are currently unimplemented.

• The Dock keyboard test requires a docking station and an external keyboard.

• The Dock PS2 mouse test requires a docking station and a PS2 mouse.

• The Dock EEPROM test requires a docking station.

Loop Back Connectors

In order to run the RS232 serial port, parallel port, and SCSI port self-test, a loop back connector is needed. The loop back may be placed on either the OmniBook port or at the end of the corresponding cable. This feature is also helpful in diagnosing a defective serial, parallel, or SCSI cable. Loop back connectors may be purchased or can easily be constructed. The following illustrations identify the correct pin-out configurations for the serial, parallel, and scsi loop back connectors.

Figure 5 - Serial Loop Back Connector

Figure 6 - Parallel Loop Back Connector

PCMCIA Type III extender card

The PCMCIA test that makes use of SyCard Technology’s SyCard also requires an extender card modified with two jumpers or with solder bridges. In order for the Sycard to be detected, CD1- and GND must be shorted together, and GND with CD2- must also be shorted together. These are both pairs of endmost pins on the extender. Once these jumpers or solder bridges are added, the SyCard will successfully be detected and the SyCard tests can be performed. See Figure 8.

Solder Bridges

Figure 8 - SyCard Solder Bridges

Command line options

When Diag is run, either from the command line, or from a batch file, a number of switches (or options) may be included to “customize” the operation of Diag. Switches must be specified separately, and must begin with either a - or a / character. Upper or lower case may be used as desired. Switches may be used in any order. The switches, a brief description, and their use are described below:

Table 4 - Diagnotic Command Line Options

Switch Description

-? Report the standard command line options available.

-! Report standard and hidden command line and keyboard commands available.

-cNxxxx Specify Nth ROM checksum. The “BIOS flash ROMs” test the flash memory for correctness. In order for Diag to maintain usefulness in the face of new and different BIOSes, a way is needed to specify the BIOS ROM values. Though the test will not fail (as of this writing) if the checksums are not specified, a ‘?’ will show after a sum to indicate checksum uncertainty. All three checksums must be specified to fully qualify the ROMs. As an example, to test a build with the

960701.ROM, the user would enter: Diag -c121E9 -c2D631 -c3C600. Batch files that need to work with both F1175 and F1360 OmniBooks may specify two checksums after each switch, the first one for the F1175 and the second one for the F1360. For example, to test the 970121 ROMs for both units, use the following switches: -c1B7386A45 -c2DC8CDC8C -c316001600.

-d Select Dock tests only. For testers wishing to test docks, this switch restricts the test shown to those that pertain to the dock only. The set of tests shown in this mode include the following: Serial port, Printer port, SCSI loopback, Audio, Floppy disk, Docked device, Dock keyboard, Dock PS2 mouse, Dock EEPROM.

-f Run Fast IR loopback mode on startup. The IR port test needs a computer running in “passive” mode to send IR data back to the computer being tested. An IR test station can be automated by having the passive computer run Diag with the -f option in its AUTOEXEC.BAT file. The key <Alt+F> can also be used to put the computer into passive mode. Press <Esc> to exit from passive mode.

-k<file> Run a Keyboard macro file. This switch is by far the most powerful and versatile in that it lets the operator set up different configurations and test sequences and play them back later just as though they were typing the commands from the keyboard. For information on creating a keyboard macro file, see the <Alt+R> command.

-m Enable Mouse keyboard control. For units that do not have a keyboard, use this option to control Diag with a mouse. For more information on this feature, see the <Alt+M> command

-r<test#> Run nth test and return exit code. For testing from a batch file, this switch can be used to run a single test and return the test result in the errorlevel. 0=pass, 1=fail, 2=aborted, 3=no loop/can’t run. Tests are specified by ordinal number counting from 1 at the top. Use the -1, -2, -3 option below to set the test level.

-s Disable control via Serial port. By default, the serial port can be used to control Diag via a host computer (running Kermit connected at 9600, N, 8, 1) when no keyboard is available, the unit cannot be easily accessed for entering commands, or remote automated operation is needed. Serial control is always automatically disabled during the serial port test, but if the serial port is used for other activities, use this switch to completely disable control.

-x Test for the eXtra key on foreign keyboards. Foreign keyboards have an extra key to the left of the space key. To include this key in the internal keyboard test, add a X parameter when running Diag. Because the keyboard test is scancode based (not ASCII character), the key names are NOT localized to their foreign equivalents.

Also some key caps have characters that cannot be displayed with the text characters available. Therefore, when running the keyboard test on a foreign keyboard, the POSITION of the key within the keyboard should match the POSITION of the key shown on the display, not necessarily the character printed on the key (although in nearly all cases, it does match). When -x is specified, the extra key appears as >< before the SP key.

-1 Mark all tests for quickest test available. This has the same effect as using the <M> command once and is mainly used with the -r switch.

-2 Mark all tests for standard test available. This has the same effect as using the <M> command twice and is mainly used with the -r switch

-3 Mark all tests for longest test available. This has the same effect as using the <M> command thrice and is mainly used with the -r switch.

EDOCK An undocumented/hidden Diag switch: Set the dock serial number. Use this

undocumented switch to set the dock serial number in the dock EEPROM. The date and time must be valid, and the date must be Jan 1 1996 or later. The serial number is set to the following code: MDDHHMMS where M is month 1-9 A-C, DD is day 01-31, HH is hour 00-23, MM is minute 00-59, and S is seconds 0-5 (tens of seconds only).

User interface commands

The user interface commands of the diagnostics program are divided into three groups: commands that select tests, commands that toggle test settings, and commands that set test parameters.

Commands for test selection

The following table describes the various commands used to select test within the diagnostics program.

Table 5 - Diagnostic Test Selection Commands

Command Description

Down Highlight the next test. At the bottom, wrap to the top test. Up Highlight previous test. At the top, wrap to the bottom test. Home Highlight the top test. End Highlight the bottom test. Space Mark the highlighted test. Tests that permit multiple levels progress from the

quickest test to the longest test then back to not selected.

M Mark all tests. If no tests are selected, <M> will select all tests to run at the

quickest possible level. Another <M> sets all tests to the standard level. Another <M> sets the longest possible level. Another <M> unselects all tests. If any other mixture of tests is selected all tests are unselected.

Enter Run all selected tests. <Enter> is used to begin running a group of selected

tests. If no tests are selected, the highlighted test is run at the standard level.

1 2 3 Run highlighted test ONLY (short, standard, long). If short or long is not

available for the specified test, the standard test is run.

<Backspace> Stop current test. The <Backspace> key is universally used to abort a test that

is running. Some tests may not be able to quickly respond to the keyboard and it may be necessary to depress the key a few times or hold the key down for it to be recognized.

Esc Exit Self-test. Upon exit, the Diag display is cleared and the DOS display is

restored. Every attempt is made to restore all settings to their previous state

upon exit (no reboot necessary in most cases).

Alt+F12 Dump the text screen to a file named DIAG.xxx where xxx begins at 000 and

increases by one each time another screen dump is captured. Screen dumps from previous runs of Diag are preserved.

? or F1 Display a help screen of keyboard commands.

Commands for toggling test settings

The following table describes the various commands used to toggle test settings within the diagnostics program.

Table 6 - Diagnostic Commands for Toggling Settings

Command Description

Ctrl+C Toggle battery Charging on/off. This command sends a request to the charging

software in the BIOS to enable charging / disable charging.

Ctrl+E Toggle ignore Errors on/off (continue after error when on). Normally Diag stops

looping when an error occurs, but with this command, Diag will continue to loop until all requested loops are complete.

Ctrl+L Toggle Logging to disk file (errors, all, all+status, none). This command appends

results to the file DIAG.LOG on the current drive and directory from which Diag was run. The data logged is either: 1) only tests which fail, 2) all tests results, 3) all test results, and all messages shown in the lower status window, or 4) none. For looping tests, the loop count and time is logged at the start of each loop. If a floppy or hard disk critical error happens when logging results, the normal “Abort, Retry, Ignore” message may not be visible depending on the display mode. A special error handler has been incorporated into diag to handle this case. A flashing message will appear on the top line should an error of this type occur. Press A, R, or I to continue. If no keyboard is available, press the Contrast Up button to Retry, or the contrast Down button to Ignore the error.

Ctrl+N Toggle Noise (beep & flash) at test completion. When a test or set of tests

completes, Diag waits for the user to enter more commands. To help notify the operator of when this happens, use Ctrl+N to cause Diag to invert the display and sound a noise until the user responds in some way.

Ctrl+P Toggle Power management on/off. Tests that require measuring power levels

may require that Power management be on or off. This can be controlled directly with this command.

Ctrl+T Toggle between the four types of mouse tests. The HP mouse tests are 1) text

mode mouse test, 2) graphic mode sine wave mouse test, 3) combined text and sine tests, and 4) graphic draw mode test.

Ctrl+V Toggle Verbose test status reporting. Some tests can report more detailed

information. These tests include: all dock related tests (reports voltages), the HP and External mouse tests (reports x/y data and button status).

Ctrl+W Toggle printing to Wired serial port (errors, all, all+status, none). Like the

<Ctrl+L> command that logs results to disk, this command similarly logs results to the com 1 serial port.

Alt+A Toggle cAche on/off. If it is necessary to disable the cache, use this command.

Processor level commands are used to perform this operation. Alt+K Toggle miKe on & line off, mike off & line on, both off. Alt+M Toggle program control with Mouse on or off. Like the -m command line option,

Alt+M enables controlling Diag with a mouse. The mouse actions listed below

have the following keyboard equivalents:

Mouse switch Key Action

Top Bumper <Up> Highlight previous test. Bottom Bumper <Down> Highlight next test. Left Button <Enter> Run current or selected tests. Right Button <Space> Mark highlighted test. Right Bumper <Backspace> Cancel currently running test. Left Bumper <Esc> Exit Diag.

Alt+P Toggle ‘Prompt to retry test after a failure.’ Sometimes it is useful to trap failures

and give the operator another opportunity to run a test before logging the test as

failed. When this option is enabled, if a test failed (other than user aborted) the

user is prompted with “Retry test now?”. If <Y> is pressed, the test is immediately

run again and no logging whatsoever of the failure is recorded anywhere. This

option has been useful for running tests manually where test fixtures need to be

installed prior to testing.

Alt+R Record keystrokes in a file for configuring tests. Used to record keystrokes for

later recall, the user is prompted for the name of a file to store the keystroke

names in (note that the extension used with the keyfile is automatically set to

.KEY). Once a unique name has been entered, every key press is recorded to the

file (except keys pressed during the execution of an individual test) until <Alt+R>

is pressed again, or Diag is exited. If Diag is exited, the final <Esc> key is

included in the key file. Please note that macro files run when Diag first starts up,

and that any keys pressed before <Alt+R> is pressed will NOT be included. In

particular, keys that select tests or test settings should be avoided before

recording a keyboard macro file. If you wish to avoid having to wait until AFTER a

set of tests is run to save the keyboard macro file simply enter all the keys you

need UP TO WHERE YOU WOULD PRESS THE ENTER KEY. At this point,

press <Esc> to exit Diag, then use EDIT or another ASCII text editor to add

“<Enter>” to the end of the file.

Alt+S Toggle Suspend hard disk at end of test. The hard disk can either be left spinning

(default) at the end of its test, or spun down and stopped.

Alt+T Toggle 1000Hz Tone on/off. The PC speaker generates a 1000Hz tone when this

option is enabled.

Alt+V Toggle Videos used between both, external, and internal. Diag can drive either or

both displays. When Diag is first run, the currently selected displays continue to

function (whatever the user has specified). The first <Alt+V> enables both

displays, the second enables the external display only, and the third enables the

internal display only.

Alt+W Walk through tests. Sometimes it is useful to advance slowly through a particular

test. By enabling this option, Diag will beep and wait for a keypress each time the

test would normally just check to see if the <Backspace> key was pressed.

The following two-key commands are hidden from general use:

Table 7 - Diagnostic Hidden Commands

Command Description

Alt+E + Alt+C Set the lost mickey Count threshold. Use this command to specify the

minimum number of “lost mickeys” at which a mouse “mickey” error can occur. The default value is 530 mickeys. See also the Alt+E + Alt+T command, and the mouse test section.

Alt+E + Alt+D Show dock EEPROM serial number (hidden function). Use this command to

verify the dock serial number is set.

Alt+E + Alt+H Set the Horizontal lost calibration speed thresholds used in the graphic draw

mouse test. The defaults limits are 300 to 500.

Alt+E + Alt+V Set the Vertical lost calibration speed thresholds used in the graphic draw

mouse test. The defaults limits are 200 to 400.

Alt+E + Alt+M Set mouse bumper failure threshold. The default number of mickeys for this is

1000. The number reflects how much bumper compression is permitted before a bumper is rejected.

Alt+E + Atl+S Set sine mouse test threshold. For mice that exhibit sine wave patterns along

the left side of the screen, use this key to specify how much will be tolerated. The default value is 10.

Alt+E + Alt+T Set the lost mickey Time threshold. Use this command to specify the minimum

number of “timer tics” at which a mouse “mickey” error can occur. The default value is 10 timer tics. See the Alt+E + Alt+C command and the mouse test section.

Alt+E + Alt+Z Shell out from Diag to a command prompt. This can be used to run small

tasks, (e.g. copy files) without losing any current diagnostic settings. When ready to return to Diag, type EXIT.

Commands for setting test parameters

The following table describes the various commands used to set test parameters within the diagnostics program.

Table 8 - Diagnostic Test Parameters

Command Description

# Set loop count limit for looping tests. By default 1 loop is run. If 0 loops are

specified, Diag will loop indefinitely. Other values will loop for the count specified.

Ctrl+A Set wakeup Alarm delay after suspend. The OmniBook can be set to

automatically wake up after a suspend by setting a wakeup alarm of 1 to 59 hours,

minutes, or seconds. By default, no wakeup is scheduled. If an alarm delay has

been set and multiple test loops are set then Diag will automatically suspend at the

completion of each loop.

Ctrl+D Set loop Delay interval. By default, looped testing runs as rapidly as possible with

no delays between loops. This command lets the user specify that each loop of

testing start from 1 to 59 hours, minutes, or seconds after the previous loop

started. No delay will occur if the tests have already run for the specified delay

time (for example, if 2 minutes of delay are specified and the tests selected ran for

2 minutes 10 seconds, then no delay would occur at the end of the loop.

Ctrl+H Report System Hardware found. This test reports on various OmniBook

components. The following are reported: CPU speed (100, 133, 150, etc); Display

technology (TFT, DSTN); Hard disk capacity (814M, 1.4G, etc); Cache size (256,

512, etc) and state (ON,OFF); OS version (varies); system RAM (16M, 24M, …

80M); and disk volume id (varies).

Ctrl+R Set Retries before reporting disk error. By default, 5 retries are permitted before a

disk error is reported. Specifying fewer retries will detect marginal media more

quickly. A related feature of Diag regarding soft read errors (checksum errors), is

that these sectors will be written back to disk to repair the checksum error.

Ctrl+S Enter Suspend state. This command will put the OmniBook into an off state

similar to pressing the Off key. Once suspended, the OmniBook will remain off

indefinitely unless a wakeup alarm has been set with <Ctrl+A>.

Alt+B Set Brightness 0-255. Specify a display brightness from 0 to 255 with this

command. This exceeds the normal range permitted with the brightness buttons

and can result in a blank display. Repeat the command with a less extreme value

to restore the display.

Alt+C Set Contrast 0-255. Systems with a DSTN display can specify a display contrast

from 0 to 255. This exceeds the normal range permitted with the contrast buttons

and can result in a blank display. Repeat the command with a less extreme value

to restore the display.

Alt+D Set device type that should be found in the dock port. Once specified, the

“Docked device” test will only pass if the correct device is found. The OmniBook

dock port can accept either a SCSI cable for connection to a tower, or a dock

device. Specify N, S, or D when prompted for nothing, SCSI cable, or dock.

Alt+F Set Fast IR loopback mode. The fast I/R test requires two OmniBooks with their

I/R ports directed at each other. One OmniBook must be run in fast IR loopback

mode. To put an OmniBook into this mode either use this command or use the /f

command line option when starting Diag. To exit this mode press the <Esc> key.

Alt+I Enter Idle state. This command puts the OmniBook in a low power state while still

maintaining full readiness to run. Press any key to resume.

Alt+N Enter a Note to log to disk file. When logging to a disk file has been enabled with

<Ctrl+L>, this command can be used to permit entering a line of text, then logging

the text to the log file DIAG.LOG

Details on using the diagnostic tests

Details for the various tests are described below. The levels permitted for each test and a brief note on hardware or other options are described.

Numerous tests involve pattern testing to determine if the hardware can accept the various data combinations required. Tests that make use of 18 data patterns use the following pattern set: 0FFFFh, 00000h, 0F0F0h, 0AAAAh, 05555h, 08080h, 04040h, 2020h, 01010h, 00808h, 00404h, 00202h, 00101h, 01111h, 02222h, 04444h, and 08888h. These data patterns are used in place of “walking bits”, “checkerboards”, and “bit stuck high/low”.

CPU

Level: 2. The CPU test contains numerous subtests as follows. The CPU register test writes the 18 data patterns to the registers and reads them back to verify correctness. The CPU arithmetic test performs ACD, ADD, DEC, DIV, IDIV, IMUL, INC, MUL, SBB and SUB with 16 and 32 bit operands. The CPU logical test performs AND, NOT, OR, and XOR with 16 and 32 bit operands. The CPU string test performs LODS, MOVS, SCAS, and STOS with 16 and 32 bit operands. The CPU interrupts / exceptions tests software interrupts and real-mode accessible exceptions; if Diag is running in a DOS box, Windows prevents testing all exceptions but divide by 0. The coprocessor tests the numeric coprocessor register stack, exception handling, arithmetic, comparison, and transcendental operations. Failures are reported by register and operation. A final test of CPU speed is performed to ensure measured speed is within 10% of the expected value, values below this will fail the test.

Cache

Level: 2. This tests the translation lookaside buffer and the Pentium on-chip cache first with register addressability, then with the 18 test patterns. No memory managers may be installed for this test to run.

RAM, motherboard

Levels: 1,2,3. The level 1 test performs an address test only with the 18 data patterns. The level 2 test performs a pattern test, address test, bus throughput, and code test. The level 3 test does what level 2 does except the pattern and address tests are repeated 10 times. The

operation of all tests depend on the presence or absence of XMS or EMS drivers. In general, if there is no XMS and no EMS driver, then memory will be accessed directly in pseudo-32-bit mode (i.e. with 4 GB selectors but from real code), if there is an XMS/EMS driver, the XMS driver will be used to access memory. The recommended environment is real mode without XMS or EMS drivers (i.e. a clean boot).

Pattern testing and address testing are similar. The pattern test sequentially writes the 18 patterns to memory and reads them back. The address test uses each individual memory location as the pattern data, but otherwise the test functions just like a pattern test.

Base memory is always pattern/address tested in 16-KB blocks. Extended memory, if no EMS/XMS drivers are present, will be tested in blocks of up to 1MB. The contents of the memory is not preserved.

Bus throughput testing is only available for base memory. The test reads memory using a tight REP LODSD loop, not checking the actual data, but looking out for parity errors (from the memory, cache, and interface chips).

Code test is only available for extended memory. The test writes a 1-MB program to memory, switches the CPU to protected mode and runs the program that is in extended memory. This approach tests not only the data cache and fetch of a CPU, but also the code cache and fetch. Exceptions and parity errors are also monitored in protected mode.

RAM, plug in

Levels: 1,2,3. These tests are identical to the RAM, motherboard tests except the RAM on the plug in card is tested.

BIOS

Level: 2 - command line option. This tests the 256k bytes of flash ROM memory. Depending on whether or not checksums are specified on the command line (with -C1xxxx -C2xxxx and C3xxxx) the test either confirms the checksums specified or just reports the checksums found. If the checksums are unknown, run this test manually once to determine their value, then use these values for regular testing by specifying the checksums reported on the command line when Diag runs. The BIOS is logically divided into three sections named: C-F (BIOS memory C000:0000 to F000:7FFF), Altera (BIOS memory F000:8000 to F000:BFFF), and Boot (BIOS memory from F000:C000 to F000:FFFF).

CMOS

Level: 2. This tests CMOS addresses 010h - 03Fh of the nonvolatile real time clock CMOS RAM with the 18 data patterns, and tests for a correct CMOS checksum.

Upper PC Card

Level: 2. This test uses the Sycard Technology PCMCIA test to check the TI PCI-1130,1131 controller. The controller is checked for I/O signals, VCC and VPP voltages, proper audio signal generation, INPACK number generation, 3.3 and 5 volt operation and other aspects as detailed in the following listing of a typical test result. Please note that during the Audio out test a 1KHz tone should be heard. The Sycard test card is manufactured by Sycard Technology of Santa Clara, California.

Figure 9 - Sycard Test Results

The OmniBook model F1360 supports zoom video and Cardbus. If a Sycard model 450 PCMCIA socket tester is found (in the upper slot only), a zoom video test will be run on that slot.

Lower PC Card

Level: 2. This test operates like the upper PC card test, but for the lower slot. Manual insertion is generally required to test both slots.

Timers

Level: 2. This test checks that all three system timers are counting correctly, and that the control lines of programmable clock 2 are functioning properly.

Real time clock

Level: 2. This test checks for generation of IRQ0, generation of interrupt 1C, time updates, periodic interrupt, alarm interrupt, and time/date roll-over.

IRQ controller

Level: 2. This test checks the IRQ controllers’ mask register, request register, in-service register, poll command, and EOI commands. Note that Windows prevents testing the poll command.

DMA controller

Level: 2. This test checks the DMA registers and page registers with the pattern registers, then a DMA read/write transfer is tested. Note that Windows prevents testing the DMA controller.

IR port

Level: 2. This test requires a second OmniBook running in fast IR loopback mode. The second OmniBook can be put in fast IR loopback mode either by running Diag with the /F command line option, or by first running Diag then pressing Alt+F. When in loopback mode, all IR data

received is echoed back to the host. The IR port is first tested in slow mode by sending / receiving data packets at 115K baud. If this passes, then data packets are transmitted in high speed at 1 megabit then 4 megabit. These IR transmission tests are repeated 3 times.

Serial port

Levels: 1,2. The level 1 test checks the internal operation of the serial port and does not require a loopback. The internal registers are pattern tested to ensure the port can interrupt the system. Then an internal loopback tests for proper internal character transmission. Finally, operation of RTS, DTR, CTS, and DSR status signals are checked.

The level 2 test performs what level 1 does plus a test at various baud rates for successful transmission of characters through a loop back connector.

Printer port

Level: 2. This test checks for command and data ports with the 18 data patterns, then uses the parallel loopback connector for proper operation of signal lines and IRQ generation.

Hard disk

Levels: 1,2,3. The level 1 test checks to ensure the internal drive signals are functioning correctly; if no errors occur the capacity of the drive is reported. The level 2 test checks all sectors on the outermost and innermost tracks as follows: a sector of data is read, the data is inverted and written, the data is read again and verified for correctness, finally the original data is written back. At level 3, all data between the inner and outer tracks are read to ensure data integrity. Any failure aborts further testing.

Note that the internal hard disk remaps the physical characteristics of the drive to a logical collection of tracks, heads and sectors.

Floppy disk

Levels: 1,2,3. This test operates similarly to the hard disk test. Note that the level 1 test does not require that the floppy disk be connected.

Battery

Level: 2. This test simply reports the status of the charging system: battery type (none or lithium ion); charge state (NA - battery powered (no AC), NC - no charging, the battery is full, FC - fast charging, TC - trickle charging, or EC - error charging); percent of battery charged (0 - 100); battery voltage, and ambient system temperature (Celsius).

SCSI loopback

Levels: 1,2,3. The level 1 test requires a dock or SCSI cable, the devices are checked for properly terminated signals. At level 2, an attached loopback device checks for opens and shorts. At level 3, the level 2 test is run, then the user is prompted to remove the loopback, then the level 1 test is run.

Keyboard

Levels: 1,2. The level 1 keyboard test checks that the keyboard responds appropriately to commands sent from the CPU. The level 2 keyboard test also checks that each key functions properly. The level 2 test passes when each key has been pressed or aborts if the <Space> or <Esc> key is pressed three times in a row. The special keys that do not generate key codes ( <Fn>, <Contrast-Up>, and <Contrast-down> ) are tested after the other keys have been tested. Press the key when prompted to complete the keyboard test. The display shown during the main test mirrors the layout of the OmniBook keyboard.

Figure 10 - Keyboard Test Screen

HP mouse

Levels: 1,2. The HP mouse consists of a pop-up device with two mouse buttons. A sliding bar holds this to the computer. Internal sensors detect when the mouse is against a top, bottom, inner or outer edge. The output from the mouse is scaled so that moving the mouse from top to bottom or left to right will match the physical dimensions of the display.

The level 1 checks that the mouse responds properly to reset and related commands. The level 2 test lets you operate the mouse and check for button, bumper, and motion activity in both graphical or textual ways. The mouse test can be set to run in any of four modes selected using the <Ctrl+T> key to toggle from mode to mode. The first and default mode presents the mouse test screen used for testing general mouse movement, bumper, and button functionality. The second mode is designed for measuring the “sine” mouse characteristics. The third mode runs both the first and second modes. The fourth mode lets the operator draw on the screen similar to how Paintbrush operates to test for button use and motion continuity. Each test is described separately below.

Text mode mouse test

This is the default mouse test. The upper right corner of the screen shows the HP mouse, drawn with line characters. In and around the mouse are names for mouse events. Initially, all events are blinking to indicate that they have not been tested. When an event is active, it is displayed in red text on a green background. After an event becomes inactive, it is displayed in green on a black background.

The mouse is first tested in “I/O” mode: bumpers are observable as switches and do not cause the mouse position to change (as is the normal case). After all switches have been operated and the mouse moved in all directions, press a key to conclude the I/O mode test and begin the PS2 mode test. In the PS2 mode, the bumpers are no longer detectable switches but rather cause

the mouse position to change. Press both buttons and move the mouse in all directions, then press a key again to exit the test. This will end the text mode mouse test.

IMPORTANT NOTE ON THE USE OF BOTH BUTTONS: any time both buttons are pressed down, a release of just one button will NOT be recognized. BOTH buttons must be released to clear the button status.

If verbose mode is enabled with Ctrl+V, then all switch changes are reported in a scrolling window along the left edge. The following codes are used to report the various switches:

IN the left, or inner bumper is engaged OUT the right, or outer bumper is

engaged

TOP the top bumper is engaged BOT the bottom bumper is engaged LEFT the left mouse button is engaged

RIGHT the right mouse button is engaged Note: in PS2 mode, only LEFT and RIGHT are reported. Whenever a button or switch engages or disengages, the current state of all switches and the

current mouse position is scrolled up into the display, and then the new state of the switches is reported. If it is a button that is pressed, then the mouse position variables are also cleared to 0.

Mouse positions are indicated in a unit called mickeys, and there are roughly 2950 mickeys in the horizontal (X) direction, and 1695 mickeys in the vertical (Y) direction. If the mouse is moved very rapidly (faster than practical use will permit), signal loss occurs. To test for acceptable signal strength the mouse should be moved right and left against both edge stops repeatedly. After each full cycle, the time taken to complete the cycle together with the count of lost mickeys is displayed in a table in the lower right portion of the screen. If the number of lost mickeys is greater than the set limit and the time to complete the cycle is also longer than the set limit, then Diag will report a MICKEY error. To clear the table of results (either to retest or run the test in the perpendicular direction) press both mouse buttons simultaneously.

The TIC column reports the number of timer tics (1/18th of a second per tic) taken to move from one bumper to the opposite one and back again. The CUR column reports the number of mickeys off for the current motion cycle. The MIN column reports the minimum counts ever recorded at that speed. The AVG column reports the average number of counts at that speed. The MAX column reports the maximum counts ever recorded at that speed.

A sample screen dump for the text mode mouse test appears below. The results on the left half of the display were generated from having verbose mode enabled with Ctrl+V. The results in the lower right corner were generated by moving the mouse right and left against the bumpers.

Graphic mode mouse sine test

This mouse test is used to measure the maximum “sine effect” of the mouse. To select this test, press <Ctrl+T> once before running the mouse test. When run, the screen switches to an 800x600 graphic mode, a blue box is drawn scaled to the expected distance the mouse can move, and a prompt appears along top line as follows:

FOLLOW THE FROM CORNER TO CORNER. PRESS MOUSE INTO EDGE BUMPERS AS YOU MOVE.

Figure 12 - Mouse Test Screen (graphics mode)

As the prompt indicates, to run this test, you must move the mouse to the corner where the white box is displayed (initially the top right corner). When you activate BOTH bumpers at that corner, the white box moves counterclockwise to the next corner. KEEP THE MOUSE PRESSED AGAINST THE TOP BUMPER AS YOU MOVE. In order to ensure the mouse is moving in a straight line, the mouse must stay in contact with the bumper. As you move the mouse, the path of the mouse is drawn on the display. Move the mouse all the way to the top left corner and press the mouse into the top left corner (careful not to press so hard that you “park” the mouse). Once you engage BOTH bumpers at the new corner, the white box will advance to the next corner. It is important to observe the white box to ensure that you have indeed engaged BOTH bumpers at the corner you are moving to. To help you know when a bumper is engaged, a white bar is displayed along an edge whenever the bumper for that edge is engaged. Continue to move the mouse counterclockwise until you reach the lower right corner. At this point you should see a red trail of dots indicating the path the mouse has traveled. This completes the first test cycle. Now continue moving the mouse to the top right corner again to begin the second (and last) test cycle. Blue is used during the second cycle to distinguish the first cycle from the second. SUCCESSFUL OPERATION OF THIS TEST REQUIRES THAT THE MOUSE BE MOVED TO THE CORNER WHERE THE WHITE BOX APPEARS; WHEN YOU GET TO THE CORNER, GENTLY PRESS THE MOUSE INTO THE CORNER UNTIL BOTH BUMPERS ARE ENGAGED. WHEN THIS IS DONE, THE WHITE BLOCK WILL ADVANCE TO THE NEXT CORNER.

As the mouse moves, the status of the mouse is reported along the top line, for example: Cycle=1/2, X=1050,Y=1, Err^=3 Errv=0 TopEdgeErr=0 BotEdgeErr=0

Cycle indicates which test cycle is in progress. X indicates the X position (0 is the left edge). Y indicates the Y position (0 is the top edge). Err^ indicates the current maximum error drift upward. Errv indicates the current maximum error drift downward. TopEdgeErr indicates the maximum total sine error along the top edge.

BotEdgeErr indicates the maximum total sine error along the bottom edge.

When the two cycles are complete, the maximum of the top and bottom errors is compared against a test threshold. If above, the test fails, else the test passes. The default threshold is 10 pixels. The threshold can be set with the command key <Alt+E><Alt+S>.

NOTE: for test stations that have no “bumpers” to indicate edge detection, the operator must move the mouse to the top right corner, then press either mouse button to indicate the mouse is in position. Proceed counterclockwise as normally, keeping the mouse pressed against the edge of the test fixture.

Text mouse and graphic sine mouse tests selected.

This test simply combines the first and second mouse tests. Note that the sine test is not repeated after the PS-2 text mode mouse test.

Graphic draw screen mouse test selected.

This test lets the operator draw on the display to visually inspect for the degree of mouse sine. Hold the left button to draw in blue, the right to draw in yellow, and both to draw in green. The cursor is a red heart shape. The prompt for the test is as follows:

LEFT=BLUE RIGHT=YELLOW BOTH=GREEN. ENTER OR ^ TO PASS, OTHERS FAIL The raw mouse coordinate position is also reported to the right of the prompt. Additionally, as

bumper or button events occur, these events are reported on the right end of the top line as rightward scrolling text that changes from white to red as new events occur. The characters L, R, and four arrows pointing to each side indicate the event that has just occurred.

The mouse can be toggled between manual and automatic calibration. The current selection is indicated by the word MANU or AUTO in the top left corner. Change the selection by pressing the mouse into the top left corner. When manual calibration is selected, move the mouse to each edge to calibrate the mouse (permit movement to all screen positions). When automatic calibration is selected, move the mouse to an edge and hold it there to calibrate the mouse.

After drawing as desired, press <Enter> or the contrast up button (^) to indicate pass, any other to indicate failure.

This test is can also be used for determining button signal strength at various positions on the screen. Hold both buttons and draw to all regions of the display. Green dots only should appear on the screen as you draw. Blue or yellow (or nothing at all) indicate button signal strength loss.

Mouse Calibration testing. To begin measuring lost calibration due to speed in the vertical [horizontal] direction, move the mouse against the upper [left] edge and press the left mouse button. The top line will prompt the operator to move the mouse in the selected direction. With each sweep of the mouse the speed will be displayed within the expected speed range (e.g. a speed of 400 when the low limit is 300 and the high limit is 500 shows as: 300<400<500 ). If the speed is below the low limit the pixels are colored blue, if above the high limit they are colored red, if within the limits they are colored white. To end speed testing with success, press <Enter> or <Contrast_Up>. Press any other key to end with failure. To resume normal draw mode, move the mouse to either the bottom or right edge and press the left button. If failure is returned, the message “Vertical calibration lost”, or “Horizontal calibration lost” is reported.

Audio

Level: 2. This test checks the SoundBlaster compatible audio sound system. The DSP chip, DMA Channel, and Interrupt Lines are checked for proper operation. An audible sound test completes the test; a bong sound alternating between left and right speakers should be heard.

Display

Levels: 1,2,3. This test checks multiple display subsystems. When manual testing is done, the display pixels are first tested with 7 operator-paced test patterns: one each for white, red, green, blue, and black; then a vertical stripe pattern followed by a random display pattern. Press Enter or Contrast Up to pass, Esc or Contrast Down to fail, until the automated test begins. The automated display test first tests video memory by flipping to all video modes supported while writing / reading the video buffer with the 18 test patterns. Lastly, the VGA controller registers and VGA color-DAC registers are tested for proper operation.

Docked device

Levels: 1,2. The dock port can be left unconnected, connected to a SCSI tower via SCSI cable or connected to a dock. The level 1 test simply reports what is connected. If a specific device has been specified with the <Alt+D> command, then the test will report an error if anything other than that which what was specified is found. If a dock is connected and level 2 is selected, then the dock LED’s and latch are tested by blinking the selected LED and locking/unlocking. Respond ‘Y’ or ‘N’ as prompted to pass or fail each test depending on the observed performance.

SCSI CD ROM

Levels: 1,2. This test checks a SCSI CD ROM using the MSCDEX API. Instead of a clean boot, drivers must be loaded in CONFIG.SYS and AUTOEXEC.BAT. The following are a minimum driver set to enable SCSI CD’s as well as SCSI hard disks. Note: the directories listed below are the default.

CONFIG.SYS: devicehigh=c:\scsi\aspi8xx.sys /v devicehigh=c:\scsi\symcd.sys /d:aspicd0 devicehigh=c:\scsi\symdisk.sys

AUTOEXEC.BAT: c:\windows\command\mscdex /d:aspicd0 /m:12 /l:H

The level 1 test does a quick random scan of the CD. The level 2 test does a linear scan, random scan, and a funnel scan of the CD to test for proper operation.

SCSI Hard disk

Levels: 1,2,3. This test operates similarly to the hard disk test. If multiple SCSI hard disks are present, only the first disk is tested. Load the SCSI hard disk drivers in CONFIG.SYS and AUTOEXEC.BAT before running this test.

Dock slots

This test is unimplemented at this time.

Dock keyboard

Levels: 1,2. This test operates like the Keyboard test except that it uses a standard 101 key keyboard connected to the dock. The display shown during this test mirrors the layout of a standard 101 key keyboard. Its operation is similar to the internal keyboard test, but for an external keyboard.

Desktop Management Interface (DMI)

The Desktop Management Task Force (DMTF) was founded in 1992 by a group of leading computer manufacturers, including Hewlett-Packard, to define a standard method of managing the physical and logical components of personal computers. The result of these efforts is the Desktop Management Interface (DMI).

Description of DMI

DMI is basically a set of rules for accessing information about a personal computer. Using DMI, an application program can determine, for example, which hardware and software components are present in a personal computer, the operating system that is being used, and the number of accessory board slots that are available. Using the DMI interface, a local or remote application program can check what hardware and software components are installed on your computer, how well they are working, and whether any needs replacing.

All this information is stored in a special Management Information Format (MIF) file, installed on each personal computer as part of the DMI package. The MIF file specifies information about components at two levels:

• Groups contain all the information concerning a particular hardware or software component. If more than one component of the same type is present, as is often the case with serial ports and hard disk drives, a group is repeated.

• Attributes are specific items of information relating to a group. Attributes of the Mouse group, for example, include the number of mouse buttons and the name and version number of the mouse driver being used.

Hewlett-Packard has developed a number of extensions to DMI to allow the enhanced features of HP OmniBook Notebook PCs to be managed with DMI. These extensions cover:

• Administrator and user passwords.

• Tattooing: a string of characters that uniquely identifies the computer.

Note: The DMI software package included with the OmniBook can only be used with the HP OmniBook Notebook PC.

For full details of the structure of the MIF file, including an explanation of the meaning of the fields of groups and attributes and how to write an application program that accesses this information, you can access the DMTF FTP server ftp.dmtf.org or the DMTF Web Pages at the URL www.dmtf.org .

Contents of the DMI Package

The DMI software and associated documentation is supplied either pre-installed on the OmniBook’s hard disk drive or on two flexible disks. The contents of the package are the same in both cases.

Since the information accessed by the DMI software is specific to a particular computer, it must be installed on each computer separately.

The following software is supplied with the DMI package:

• A Microsoft Windows utility, SETUP.EXE, to install and initialize the DMI software.

• A Windows utility, HP TopTools. After DMI is installed, this utility can be used to display

information about the computer through the DMI.

• A Management Information Format (MIF) file. This file contains information about everything on the computer that can be controlled using DMI facilities, and is initialized during installation.

• A component code, identifying the version of MIF file to use for specific models of HP OmniBook Notebook PCs.

• Windows-compatible DMTF Service Layer software, which controls access to the DMI.

• A client agent. The HP Remote DMI Agent is a DMI application and also a network

server-side stream-based application. The Remote Agent is listening for Remote Application connection requests. If the main window of the Remote Agent is hidden, then no icon will appear on the screen when it is running.

Figure 14 provides a visual representation of the many components of the DMI package.

Figure 14 - DMI Components

Installing the DMI Package from Windows 95

The DMI package is included with the OmniBook, but it must be properly installed before it can be used. The following steps explain how.

To install the DMI preloaded on the hard disk:

• Start Windows 95, if it is not already running.

• Click on “Start”.

• Go to “Programs - HP DMI”.

• Select and run “SETUP”.

To alternatively install the DMI from floppy disks;

• Copy the DMI software from the \omnibook\drivers\win95\dmi directory of either the hard disk or Recovery CD to two floppy diskettes (copy contents of the \disk1 subdirectory to diskette #1 and contents of the \disk2 subdirectory to diskette #2).

• Start Windows 95, if it is not already running.

• Insert diskette #1 into the floppy drive.

• Select and run the SETUP program from the diskette #1.

Uninstalling the DMI Package from Windows 95

• Go to the HP DMI group.

• Launch the program “Uninstall DMI”.

• Reboot the PC.

Using the DMI Interface

For a complete explanation of how to fully take advantage of DMI, the following documentation is provided with the OmniBook:

Password Configuration

The Password Options dialog allows the User and an Administrator to control access to certain portions of the OmniBook.

If an Administrator Password is set, then modification of the PC Identification Strings or some SCU settings may be restricted by checking the appropriate checkboxes. Note that even if an Administrator Password is required to Save setup changes, the User Password (and its associated options) can still be changed without knowing the Administrator Password.

The Save setup changes option does not apply to changing PC Identification (PCID) Strings. The ability to change PCID strings can only be restricted by the Save modifications to the PC ID

texts checkbox available under Admin Password. If the User Password is set, then access to the machine may be restricted (at every turn-on, or

only at turn-ons after the machine was turned off by pressing FN+OFF). Also, if Undock is checked, a password will be required before the machine can be undocked. Also, the User Password may be required before some changes to the SCU, even if no Administrator Password has been entered.

The following table illustrates which SCU settings are subject to password protection.

Computer pauses and won’t permit kybd or mouse input for a few seconds

This is probably normal W95 behavior. The operating system processes events in the background and sometimes these interfere with the responsiveness of the application. If the hard disk has spun down to conserve power, it can take up to five seconds to spin back up. You can hear this happen. You can set the hard drive timeout equal to the computer timeout such that this does not happen often. COE users should use COE Disconnect and recognize that various COE activities (like virus scans) are happening in the background. Some file browsers (like the one in PowerPoint in the Insert Picture dialog box) will process and display a graphic image before they respond to keys. This can take twenty seconds. File browsers may wait for broken/non-existent network connections to time out.

cable and remove the batteries, then reconnect the power cable and reinstall the batteries.

Resolving Docking Station Operating Problems

Below are several scenarios of Docking Station operating problems. Possible causes and troubleshooting tips are provided for each.

If a serial or parallel device, external display, or floppy drive doesn’t work

• Make sure the OmniBook is fully inserted in the docking system. Connection should be snug.

• If the green light on the docking system isn’t on, check power to the docking system, then try

undocking and docking again.

If an external PS/2 mouse or keyboard doesn’t work

• Make sure the OmniBook is fully inserted in the docking system. Connection should be snug.

• Make sure the mouse is plugged into the correct port. The mouse and keyboard ports look the same.

• Turn the system off and on.

• Reboot the system.

• Undock the OmniBook, unplug and reconnect the ac adapter, then dock again.

If network connections don’t work

• Make sure that the LAN cable is connected.

• You normally lose connections when you turn off the system or undock. See if your network

software has a reconnect feature.

• Check your configuration files to make sure that the network drivers are properly installed.

• If the green light on the docking system isn’t on, check power to the docking system, then try

undocking and docking again.

• Check that there is no address or interrupt conflict. Check these settings on the network board—or, if the board has configuration software, check the settings using that software— see the manual for the network board. Also check these settings in your network software.

If SCSI devices don’t work

• Try rebooting and selecting a startup option that loads the SCSI drivers.

• Check the device id for conflicts.

• Make sure you turn on the SCSI devices before you reboot the system. They're configured at

boot time.

• Check your connections and SCSI termination.

• Check your configuration files to make sure that the SCSI drivers are properly installed.

• Try pushing the OmniBook into the docking system a bit harder.

• If the green light on the docking system isn’t on, check power to the docking system, then try

undocking and docking again.

• Check that there is no address or interrupt conflict. The SCSI interface normally uses I/O address 3100F and interrupt 10.

If a network-enabled system locks up when rebooting

The following hints apply to Windows for Workgroups only:

• Edit AUTOEXEC.BAT to disable Windows for Workgroups network support for all nonnetwork startup options. Add the /N switch to the WIN command (win /n) for each of the nonnetwork options.

• Edit CONFIG.SYS and AUTOEXEC.BAT to load network drivers only for the “Docking system” startup option, and not for undocked startup options.

For other operating systems:

• Check any available online tools—Device Wizard in Windows 95, for example—or check with your system administrator.

Resolving OmniBook Docking Problems

Below are several scenarios of problems that may occur when docking the OmniBook. Possible causes and troubleshooting tips are provided for each.

If your docking password isn’t accepted

• Check whether Num Lock is off.

• If you’ve forgotten your password, have your OmniBook at hand and call Hewlett-Packard

support. See your OmniBook Support and Service booklet.

If the OmniBook isn’t released after pressing the Undock button

• If you’re using a password, make sure it’s accepted.

• If you’re prompted about shutting down devices, and if no applications are using those

devices, press ENTER. Otherwise, close those applications and try undocking again.

• To override the undocking software, press a paper clip or other thin object into the security opening in the docking system. Hold it in while sliding one release latch forward.

CAUTION:

Figure 21 - Hard Drive Removal

6. Lift up on the insulator sheet and remove the hard drive. See Figure 22. The insulator sheet stays in place.

To avoid damage to the hard drive connector, do not pull the hard drive insulator up or at an angle – only straight to the right.

CAUTION:

Handle the hard drive only by its edges to avoid damage from electrostatic discharge.

Figure 22 - Hard Drive Removal (continued)

Replacement Procedure

1. If the new hard drive is from a different manufacturer than the old one, it may have screws in different positions. Determine which mounting holes in the bottom case are needed; then, if necessary, push out the rubber screw-hole covers from the inside of the bottom case. (From the outside of the computer, insert the rubber covers into the holes that are not needed.)

2. If the new hard drive has screws in different positions from the old one, the insulator sheet will also need to be adjusted. Compare the location of the screw-holes in the new hard drive with those in the insulator sheet. If there is no screw at position A, then unfold the flap at position A, and lay it flat before laying the hard drive down on the insulator. See Figure 23.

Figure 23 - Hard Drive Insulator Flap

3. Holding the new hard drive by its edges, lay it in place. Grasp the right flap of the insulator and pull to the left to engage the connection between the hard drive and the computer. See Figure 24 on page 56. If the hard drive’s connectors do not engage the computer’s connectors, pull the hard drive back out and try again. Then fold the insulator sheet back over the hard drive.

CAUTION:

4. Holding the Keyboard in place, so as not to damage the flex cables, turn the OmniBook over and re-insert the three hard drive screws removed in step one. Note, it may be necessary to support the hard drive with one hand in order for the screws to engage.

Do not force the drive into the connector or the pins may bend and cause damage to the hard drive.

Figure 24 - Inserting the Hard Drive

CAUTION:

5. Fold the Keyboard in place and tuck the Keyboard Flex Cables into the frame of the OmniBook. See Figure 25.

CAUTION:

Do not over-tighten the hard drive screws—screw just until you feel resistance (1.7 in.-lbs.). If the screws are over-tightened, the HDD may not function properly.

To avoid damage to the keyboard flex cables, they must be positioned properly in the OmniBook frame.

Figure 25 - Proper Keyboard Flex Cable Position

6. Replace the two Keyboard Screws and the remainder of the components and reboot.

Holes

Hard Disk Drive Breather Holes

Hard drives used in the OmniBook 800 have a breather hole located on the metal side of the drive (see Figure 26 for location of breather holes for both IBM and Toshiba). The hole is necessary to provide pressure equilibrium. The breather holes must not be obstructed. Any labels covering this breather hole must be removed to prevent data loss on the hard drive.

Breather

Figure 26 - IBM and Toshiba Hard Drive Breather Holes (respectively)

Just below the metal surface of the drive, a white material can be seen through the breather hole. This is a filter and should not be disturbed. A drive with this filter damaged should be considered defective.

Replacement Procedure

1. Ensure the CPU Insulator is positioned over the CPU connector on the Logic PCA.

2. Position the replacement CPU over the connector on the Logic PCA and press firmly but gently. For F1360 units, please refer to the Heat Transfer Disk information on page 68.

CAUTION:

3. Replace the remainder of the components and reboot.

To avoid damage, apply pressure to the CPU only directly above the connector.

Heat Transfer Disk

(The following information applies to F1360 units only.) With each replacement of the CPU, a new Heat Transfer Disk must be placed on the underside

of the Top Case. See Figure 38. Simply pull back the Keyboard Support Insulator, remove the old Heat Transfer Disk, center the new Heat Transfer Disk in the indentation and reposition the Insulator. Ensure the rectangle opening in the Insulator is positioned squarely over the Heat Transfer Disk so that the edges of the Insulator opening retain the disk.

Keyboard Support Insulator (p/n F1360-20004)

Heat Transfer Disk (p/n F1360-20006)

Figure 38 - Heat Transfer Disk and Keyboard Support Insulator

The heat generated by the CPU must be transferred through the CPU Thermal Coupling to the Heat Transfer Disk. See Figure 39. The material used to facilitate the heat transfer is a paraffinbased thermally conductive wax. When heated, the wax on the disk melts and flows to fill in thermally restrictive air gaps between the Top Case and the CPU.

CPU Thermal Coupling

Figure 39 - CPU Thermal Coupling

Under normal conditions, it is important not to disturb the wax residue on the Top Case and CPU. If the Top Case is replaced, it will have a new Heat Transfer Disk already in place on the Keyboard Support Plate. However, to ensure the integrity of the heat transfer, this Heat Transfer Disk should be replaced with a new disk after installation of the new Top Case Assembly.

Logic PCA Board

(HP Authorized Service Providers Only)

Electronic Serial Number

The OmniBook 800 (F1360 only) is shipped with an electronic serial number programmed in EEPROM on the Logic PCA Board. This built-in serial number will help MIS managers in tracking assets and software configuration. Serial numbers can also be used for security and in tracking lost or stolen notebooks. The Desktop Management Interface (DMI) TopTools application shipped with the OmniBook can be used to read the serial number locally and across a network.

Programming the Electronic Serial Number

All replacement Logic PCA Boards will arrive with a temporary serial number programmed in EEPROM. The following procedure provides the steps necessary to reprogram the electronic serial number.

1. After installation of the replacement Logic PCA Board and upon reboot, the OmniBook will halt with this prompt:

INVALID ELECTRONIC SERIAL NUMBER PRESS ANY KEY TO CONTINUE

2. After a key is pressed, the OmniBook will continue a normal boot process. The HP Authorized Service Provider must program a valid serial number before the OmniBook can be shipped to the customer.

3. Run the ESN.EXE program located in the c:\omnibook\diag directory.

4. The ESN program will prompt for a valid serial number.

5. Enter the serial number located on the bottom of the OmniBook. The ESN program will burn the serial number into EEPROM.

Overriding an Incorrect Electronic Serial Number

If an incorrect serial number is inadvertently burned into EEPROM, it can be corrected. Perform the following steps:

1. Run the ESN.EXE program located in the c:\omnibook\diag directory.

2. The ESN program will prompt to confirm that the serial number is incorrect. It will then generate a five (5) digit number key.

3. The HP Authorized Service Provider must contact Hewlett-Packard Technical Support at this point.

4. HP Technical Support will ask for a CZ authorization number and the five (5) digit number (from step 2).

5. HP Technical Support will provide a validation key to the HP Authorized Service Provider.

6. Enter the validation key. This will reset the electronic serial number with a temporary number.

7. Follow the above steps in Programming the Electronic Serial Number to enter the correct serial number.

Note, updating the BIOS on the OmniBook will not affect the electronic serial number.
