PCMCIA Hard Drive
Advantage:
Flexible disk drive
PCMCIA disk drive sustains 1000 g's non-operating shock (vs. 100 g's for typical
notebook competitors). The OmniBook 600 design requires additional durability
because its light weight and size makes it easy to take wherever users go. Hard
drives typically have a higher failure rate then other components due to shock.
PCMCIA hard drives stand shock and vibration better then any other hard drive.

TFT Display Quality
Note: Includes option to simultaneously display external video and
notebook display.
TFT display manufacturing is a high precision but imperfect technology and
manufacturers cannot currently produce large displays that are cosmetically perfect.
Most if not all TFT displays will exhibit some level of cosmetic imperfection. These
cosmetic imperfections may be visible to the customer under varying display
conditions and can appear as bright, dim or dark spots.
This issue is common across all vendors supplying TFT displays in their products and
is not specific to the HP OmniBook display.
The HP OmniBook TFT displays meet or exceed all TFT manufacturer's standards
for cosmetic quality of TFT displays. HP does not warrant that the displays will be
free of cosmetic imperfections.
TFT displays may have a small number of cosmetic imperfections and still conform
to the display manufacturers cosmetic quality specifications.
Here are some guidelines to use in determining what action to take on a customer
complaint of cosmetic imperfection in their TFT display:
1. The unit should be viewed in the customer's normal operating condition.
This means if the customer uses the unit predominately in DOS, or Windows, or in
some other application or combination of applications, that is where the
determination shall be made. Self test is not a normal operating condition and is not
a sufficient tool to interpret display quality.
2. In the customer's normal operating mode:
TFT Display Quality
a. If 4 or more variant pixels appear clustered in the area approximated by a
thumbprint on the display surface, then the display should be considered for
replacement.
b. On OmniBook 4000CT models, if more than 30 total pixels anywhere on the
display are bad, then the display should be considered for replacement. On
OmniBook 600CT and OmniBook 5000CT models, if more than 15 total pixels
anywhere on the display are bad, then the display should be considered for
replacement.
These are the only conditions in this guideline that may call for a replacement due to
a defect in material or workmanship based on the HP Limited Warranty Statement.
3. If a display is considered for replacement, it should be clear to the customer that
cosmetic variations on the replacement display may also exist, and may require the
customer to use a work-around to obscure the cosmetic imperfection.
4. Customers with cosmetic-based complaints only, that do not conform to the above
conditions and tests will not normally be considered for display replacement. It will
be left to the judgment of the HP-responsible person who, in working with the
customer, to identify work-arounds that are reasonable and appropriate for the
individual customer. Customers who must have a more perfect display solution
should consider switching to an OmniBook with a DSTN display.
We expect over time that the industry will continue to improve in their ability to
produce displays with fewer inherent cosmetic imperfections and will adjust our HP
guidelines as the improvements are implemented.
User interface
Power
Keyboard: 85-key, touch-type keyboard; industry standard, full sized key spacing
with embedded numeric keypad. Includes 12 function [Fn] keys located on the top

The PCMCIA hard drive in the OmniBook is sensitive to rapid changes in
temperature and humidity (e.g. turning on an OmniBook in an air conditioned
building immediatly after removing it from a hot and humid car trunk). This can
permanently damage the hard drive. The OmniBook should be allowed to reach
room temperature before turning on the product.

Note: These are the tests that HP designs notebook computers to
meet. Due to normal variations in the components of individual
machines, some machines will perform better and some won't perform
as well. HP does not guarantee that every notebook computer will
meet these specifications.
BIOS

Software and
Operating System
Plug and Play BIOS stored in EEPROM.
User Upgradable via floppy drive. Instructions for how to upgrade the BIOS come
with the BIOS in a readme.txt file.
BIOS comes in 5 languages (English, French, German, Italian, and Spanish).
When upgrading/replacing a BIOS, ensure that the BIOS language matches the
software on the hard drive. Always check to make sure the correct BIOS is
installed after replacing the motherboard.
A corrupt BIOS that prevents the machine from booting requires either a special
BIOS recovery tool (check your Product Support Plan to see if this tool is available
to you) or a motherboard replacement. The BIOS can be corrupted by interrupting
a BIOS upgrade in the middle of the process.
Some models require that the BIOS matches the operating system. Check your
Product Support Plan to see if this applies to the machine you are working on.

OmniBook 600 at this time.
Physical security from Kensington Lock
System password: When the password setting is enabled, a window shall pop-up
to allow the user to enter the old password, enter a new password and to verify the
new password. When no password is currently in use, the Old Password field is
disabled. To provide both security and convenience, the user can specify whether
a power-on password is required. When enabled, the unit will prompt for password
at turn-on (either after boot or restore from disk). If the user forgets the system
password, there is a master password that will unlock the OmniBook. The user
must call the Mobile Computing Division Technical Support to follow a process to
unlock the OmniBook.
Password Decode
If the user forgets the system password, there is a master password that will unlock
the Omnibook. The user calls Technical Support to determine this master
password as follows:
1. Support will tell the user the keys to type at the password entry screen:
[alt][shft][f10]
2. The Omnibook generates and displays an encoded master password. This is
displayed under the normal password entry area. At this point, this is the only
password that will unlock the Omnibook unless the user presses [ESC] to remove
the encoded master from the password entry screen. Then the user's stored
password can be entered.
3. The user reads the encoded master password to Support.
4. Support runs a program that decodes the encoded password, and reads the
decoded password (alphanumeric) to the user.
5. The user types in the decoded password.
6. Omnibook decodes the encoded master password it generated and compares it
to the decoded password typed in by the user.
7. If the two passwords match, the Omnibook is unlocked. The forgotten password
is automatically erased. Support can then guide the user through the process of
entering a new password.
8. If the two passwords do not match, the previous sequence must be repeated
until the user correctly enters a master password.
Password Decode
Policy
The encoded master password is an eight-character alphanumeric sequence that
the Omnibook generates at random every time the appropriate keys are pressed
in the password entry screen. Because it is generated randomly, a master
password can only be used to unlock the Omnibook once. If the user forgets the
password at another time, it will require another call to Support. (If the user
presses the appropriate keys by mistake, pressing [ESC] will allow entering the
stored password.)
The password descramble programs for the HP OmniBook PCs are protected as
HP Company Private information. They may not be copied, backed-up, printed or
distributed. There are only six official copies of each program.
In addition to protecting the program itself, it's use is also controlled. HewlettPackard and authorized support providers must ensure with written evidence that
the OmniBook that is being "descrambled" is actually in the hands of the unit's
actual and current owner. This requires a sales receipt showing the unit serial
number and owner's name, or a written statement from the owner attesting that
they are the owner of the unit. The statement can be a FAX copy of the document.
The fact that the unit is in the hands of an HP representative on the behalf of the
customer is not evidence of ownership. In addition, HP will not descramble a unit
for any non-owner, even if it involves law enforcement agencies. If you receive
such a request, you should notify management and HP Corporate Legal
immediately. (These requests may require a court order prior to our participation.)
Further, you must log the name, serial number and date of the running of the
descramble program, and file the written backup with the log. The log and backup
is subject to standard record's retention process and review.
The final issue relating to descramble of passwords is that HP cannot provide
information to users that would assist them in improperly descrambling a password
and opening a unit.
Notebook Hardware Structure
Field Replaceable Assemblies
Battery Module (End User Replaceable)
The Battery Modules is user replaceable. To remove it, turn the OmniBook off. If AC power is plugged in,
don't remove the AC power while the battery is out. Turn the unit over. Slide the two latches away from body
of battery and lift battery out.
Reverse the procedure to install a new Battery or Floppy Disk Drive Module. If AC power is not plugged in,
hold down the F4 key and press the on botton to force the OmniBook to check the level of the new battery.
The latches that hold the battery in place should be replaced if damaged. These latches slide off once the
battery is removed. Inspect the rails that the latches slide on. If these rails are badly damaged, the base
exchange unit must be replaced to correct damaged rails.
Warning: Be careful not to short the terminals on the battery, this can generate a lot of heat, causing burns
and fire as well as damage to the battery.
Keyboard (Hewlett-Packard Authorized Service Providers Only)
To remove the keyboard of the OmniBook 600, insert the Keyboard Removal Tool (see the Product Support
Plan for a part number) or a thin metal spatula between the keyboard assembly and the top case just above
the F8 function key. Catch the front edge of the spatula under the keyboard assembly and push the upper
edge of the spatula toward the display. The center of the keyboard assembly will pop up. Continue pulling
up the center of the keyboard assembly allowing it to flex until the tabs on either side of the back of the
keyboard slide out of their slots. The keyboard can then be rotated forward to allow access to the keyboard
cables.
Slide the sleeves of the keyboard connectors forward and remove the cables (see illustration to the left for
removal of cables). A small probe will help get to the sleeves and in alignment of the cable during
installation.
Once the keyboard is out, check the two plastic pyramids (see inset in diagram above) to see if they are
sharp or flat on top. If they are sharp, flatten them slightly (1/8") with a blunt punch. These plastic pyramids
can cause damage to the keyboard cables over time.
To install the keyboard reverse the above procedure. Make sure that the keyboard cables are lined up
properly with the keyboard cable connectors when installing the cables.
Mouse Assembly (End User Replaceable)
The Mouse Assembly is user replaceable on the OmniBook 600. To remove mouse assembly, push the
mouse button above the keyboard near the right side of the unit just above the On/Off key. The mouse
should partially eject out the right side of the machine. Grab the mouse and pull out firmly. The whole
assembly will detach.
To replace the mouse, insert the tab of the mouse into the slot in the back of the mouse housing. Slide the
mouse in place. It takes a firm push to get the mouse over the detent that keeps it in place
Early mice on the OmniBook 600 had some reliability problems. Check the mouse date code by extending
the mouse button assembly (pinch the mouse button assembly and lift up) and looking inside the assembly.
If the mouse has a date code earlier then 95-37 (year - week #) the mouse should be replaced even if it still
functions.
Hard Disk Drive (End User Replaceable)
The Hard Disk Drive (HDD) is user replaceable.
To remove the Hard Disk Drive, exit all programs and exit windows, turn unit off, disconnect unit from AC
power, turn unit over, and remove battery. Slide the tabs toward each other as shown in the diagram below..
Pull the Hard Disk Drive and Tray Assy HDD out the right side of the unit.
Reverse the procedure for installation. Note: It is difficult to remove the Hard Disk Drive without the Tray
Assy HDD. Remember to use the tray!
Follow the instructions with the recovery disks or CD ROM to restore the hard disk drive image.
The 170 MByte Hard Disk Drives are no longer available. All bad 170MByte drives should be replaced with
260MByte drives.
Separating Topcase and Bottom Case, Removing Display Assy and Service Keyboard Topcase (Hewlett-Packard
Authorized Service Providers Only)
First, remove the pop-out mouse assy, keyboard, and battery. Then remove the four rubber feet. The feet
are pressed in place and can be removed by prying them up with a metal probe or a straight pin. Next
remove the torx drive screws - use a T6 driver - from the bottom case (see diagram below). Then remove
the one Phillips head screw located in the depression where the pop-out mouse is stored.
Turn the unit right side up with the display closed. Lift up on the front topcase seam where it meets the
bottom case near the PCMCIA card eject lever. Once the topcase is separated from the bottom case, rotate
the topcase/display assembly around the display cable. Be careful not to turn the Keyboard Bottom Case
upside down at this point. The mouse button is now loose and will fall out along with the Spring Mouse
Button. The Spring Mouse Button is very small and difficult to see. See the diagram on next page.
Disconnect the display Assy connector from the Motherboard (Exch PCA). If the Motherboard, Microphone,
Mouse Button, or Card Eject arm are going to be replaced, no further disassembly of the Service Keyboard
Topcase or of the Display Assy is required.
To remove the Display Assy, first remove the Ferrite beads from the Display Assy cable. Then, carefully
feed the cable up through the Service Keyboard Topcase.
The Topcase Service Assembly does not include the display contrast controls. If the topcase needs to be
replaced, be sure to order the contrast controls as well. The Topcase Service Assembly includes all the
labels normally on the topcase.
The Bottom Service Assembly contains all the labels normally on the bottom case as well as the Security
Plate (located inside the Kensington Lock slot) and the Battery Door Latches. The speaker (shown on next
page), the Pivot Door and Spring (shown below) must be ordered separately.
Removing the Motherboard (Exch PCA) (Hewlett-Packard Authorized
Service Providers Only)
Before removing the Motherboard you must first separate the topcase and bottomcase, remove the hard
drive, RAM Expansion (if installed) and any installed PCMCIA cards.
Remove Mouse Button and Spring Mouse Button by lifting up on the Mouse button and turning the bottom
case upside down to remove Spring Mouse Button. Remove the card eject arm. The Card Eject Button and
Spring Eject Flash Card do not need to be removed.
Disconnect the speaker wire connector and the ribbon cable from the Paw Mech Assy from the Motherboard.
Notice how the Ribbon cable from the Paw Mech Assy is routed. Remove the 6 torx drive screws - T^ drive that hold the Motherboard in place. There are 4 silver torx head screws that hold the two PCMCIA
connectors in place on the Motherboard and one additional silver torx drive screw that holds the RAM
Expansion connector in place. These screws should not be removed. To remove the Motherboard, lift up on
the VGA connector while holding the Keyboard Bottom Case in place.
Once the Motherboard has been removed you have access to the Speaker, Paw Mech Assy, Spring Eject
Plastic Mouse, Mouse Eject Arm, and Shield.
To reassemble, reverse the above procedures. Make sure the Shield is in place and that the ribbon cable
from the Paw Mech Assy is properly routed. If the ribbon cable is not properly routed, it will interfere with the
installation of the hard disk drive.
Small parts
The, I/O door, Rubber feet, and Flash card tray are all replaceable.
To remove the I/O door, open it fully. Flex the door so that the center hinge separates from back case.
Continue to flex until side pins clear holes in back case. To reassemble, just reverse the procedure.
The rubber feet are pressed into the bottom case. To remove, stick a pin into the foot from the side and pull
the foot up. To install a new foot, insert into hole and press firmly.
The Flash card tray assembly (PCMCIA accessory Tray) is removed and installed in the same manner as the
Hard Disk Drive.
Installing memory
The OmniBook 600 family has one location for expanding system RAM. The memory location is on the front
surface of the OmniBook 600. The RAM door is remove by pushing down. To remove RAM already
installed, rotate the pull tab out from under the RAM module and pull the module out.
To install a RAM module, use the reverse procedure. Make sure that the pull tab is on the bottom.
Ehhanced Port Replicator
The Enhanced Port Replicator Accessory consists of no field replaceable components. If any
component of the dock is defective, the entire unit must be replaced.
Troubleshooting Tips:
PowerMaintain power to the port replicator. If power is interrupted, SCSI devices
and network connections are lock. The Unlock button doesn't work without
power.
External Keyboard/MouseUndock and remove power before connecting or removing an external
keyboard or mouse. To enable a serial mouse after docking, reboot the
system. (A PS/2 mouse does not require a reboot.)
SCSI DevicesThe SCSI port uses I/O addresses 340-35F and interrupt 10.
Troubleshooting and Repair
Known Hardware
Issues (DOS 6.2 and
Windows 3.11)
Unit is HOT while charging.
Battery is HOT
Display may discolor while charging closed
Clears up when cooler in a few seconds.
Display has 1 minute warm up period
Brightness control disabled during that time
After first boot, display may need contrast adjustment to make it readable.
Press and hold (UP) contrast button until display is readable.
Power Supply is noisy (customers often describe the noise as a whine).
This does not mean that the hard drive is going bad.
Users who put multiple business cards in the card slot may force card holder to peel
up.
AC Adapter is 40W and it is possible to "chain" or configure the system with cards
and devices that require more than 40W.
System may do hardware shut down if not properly powered.
Known Hardware
Issues (DOS 6.2 and
Windows 3.11)
Battery life is VERY use and user dependent.
Modems use power just by being plugged in.
Some software prevents APM from working and may result in reduced battery
life.
Some programs with their own cursor control may prevent suspend.
Example: Lotus 123 v4(Windows)
Full charge is essential for average battery life.
Green light does not mean FULL
Pressing [off], [f4][ON] may result in inconsistent battery indications
Resets ALL information about battery, including battery history so the
battery indicator could be inaccurate.
With the unit plugged into AC, battery is not under load and battery
indicator may "bounce" up and then quickly down.
It DOES, however, reread the battery and provide a fresh look at the
battery condition when the agent suspects a bad battery or inconsistency
between the battery indicator and the actual battery condition.
Some early F1065A and F1066A models had bad floppy disk drive cables. When
testing for a bad floppy disk drive make sure you test it with the customer's cable.
Early mice on the OmniBook 600 had some reliability problems. Check the mouse
date code by extending the mouse button assembly (pinch the mouse button
assembly and lift up) and looking inside the assembly. If the mouse has a date code
ealier then 95-37 (year - week #) the mouse should be replaced even if it still
functions.

OmniBook Self-Test
(Not all units have
this self test builtin)
First POST: BEEP
CODES
The complete self-test procedure is documented in the OmniBook 600 Operating
Guide.
A note about interpreting self-test results.
Self-test alone should not be used to diagnose a hardware problem. If
the self-test results are absolutely clear and repeatable, confirm the
results with at least two other non-self-test failure symptoms.
The OmniBook 600 BIOS includes a POST facility that tests a number of hardware
and firmware items in the unit at each cold-start (BOOT or RESET).
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:
all accessories are removed, including memory cards, external floppy,
port expander, modems, PCMCIA cards, LAN cards, printers, VGA-out
cables, external pointing devices, clean AC power is provided (no
"chained" battery chargers or auto adapters), and press reset.
Beep codes
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 nonfatal system board errors.

DISPLAY CODES
There are a number of 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 (i.e.,
03044). It is extremely important not to interpret a failure code immediately as a
hardware failure until:
all accessories are removed, including memory cards external floppy, port
expander, modems, PCMCIA cards, LAN cards, printers, VGA-out cables,
external pointing devices, 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.
NOTE: make sure the display is adjusted to be visible.
