Note: Includes option to simultaneously display external video and notebook

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.
18
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:
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.
User interface
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.

Instant on: Maintains OmniBook in ready-to-work state for weeks on a full charge;
when turned on it returns instantly to previous state. No waiting for restoring from
disk. Accomplished by the use of self refreshed DRAM technology. Note: The
OmniBook 5000 utilizes the same technology as the OmniBook 600 to achieve the
instant on feature.
Smart Battery: The OmniBook 5000 uses "Smart" battery technology. The battery
itself contains an ASIC (Application Specific Integrated Circuit) that is able to
continuously test and track the status of the battery. The OmniBook BIOS can then
receive high-quality information about the battery condition directly from the
hardware and not interrupt the CPU. The OmniBook 5000 no longer has to rely on
software to determine the condition of the battery. The condition can be checked
using two methods that receive information from the BIOS (CONFIGURATION
[fn][f2], Windows Control Panel Power).

Security
Password Decode
Physical security from Kensington Lock
2 - level password protection (admin and user levels), PC ID (tattooing)
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.
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.
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.)
23
Password Decode
Policy
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.

System Configuration
The system screen contains the processor and memory information for the user to glance at. It also
allows the user to set the date and time. The real time clock is not changed until the user exits the
setup program. The user can also enable or disable the processor cache.
When the user decides to enable a password, a pop up window requests the old password, new
password and confirmation of the new password. Hard drives or mass storage are not affected by the
password--only the turn-on condition.

Troubleshooting and Repair
OmniBook Self-Test
First POST: BEEP CODES
The complete self-test procedure is documented in the OmniBook
5000 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 5000 BIOS includes a POST facility that tests a
number of hardware and firmware items in the unit at each coldstart (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.
If the unit still fails to boot, it requires service.
Beep codes
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.
49
Beep Code Description
none CPU register test in progress or failure.
1-1-1 CPU Failure
1-1-3 CMOS write/read test in progress or failure. Failure will result in a system
halt.
1-1-4 ROM BIOS checksum test in progress or failure. Failure will result in a
system halt. Checksum test - All of the values in a given range of
locations are added together. The range includes a location which, when
added to sum of the ranges, will produce a known result (0). BIOS is in
FLASH and can only be fixed through replacement of the flash device (not
a field repairable item) Customer units should be returned for repair.
1-2-1 Programmable interval timer 0 test in progress or failure. Failure will
result in a system
1-2-2 DMA channel 0 address and count register test in progress or failure.
Failure will result in a system halt.
1-2-3 DMA page register write/read test in progress or failure. Failure will result
in a system halt.
1-3-1 RAM refresh verification test in progress or failure. Failure will result in a
system halt.
1-3-2 SMI RAM Bad. Failure will result in a system halt.
None First 64K RAM test in progress. No specific test is performed - just
indicates that the test is beginning (i.e., no failure).
1-3-3 First 64K RAM chip or data line failure, multi-bit. Failure results in a
system halt.
1-4-2 Parity failure first 64K RAM. Failure results in a system halt.
2-1-1/2/3/4 First 64K RAM chip or data line failure on bit x. Failure results in a system
halt.

halt.
3-1-2 Master DMA register test in progress or failure. Failure results in a system
halt.
50
3-1-3 Master interrupt mask register test in progress or failure. Failure results in
a system halt.
3-1-4 Slave interrupt mask register test in progress or failure. Failure results in
a system halt.
3-2-4 Keyboard controller test in progress or failure. Failure results in a system
halt.
3-3-4 Screen memory test in progress or failure. Failure will result in a beep
code but not a system halt.
3-4-1 Video Retrace Failure.
3-4-2 Screen retrace test in progress.
3-4-3 Screen retrace test failure
4-2-1 Timer-tick interrupt test in progress or failure. An error message is
displayed on the screen. The system does not halt.
4-2-2 Shutdown test in progress or failure. If possible, the BIOS will continue
POST, skipping the memory tests.
4-2-3 Gate A20 failure. An error message is displayed on the screen and the
memory tests are suspended. The system does not halt.
4-2-4 Unexpected interrupt in protected mode. The system does not half when
an unexpected interrupt occurs.
4-3-1 RAM test of memory above 64K in progress or failure. POST will
continue.
4-3-2 Programmable interval timer channel 2 test in progress or failure. POST
will continue.
4-3-4 Real-time clock text in progress
4-4-1 Serial port test in progress or failure. POST will continue.

Last POST:
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.
52
PhoenixBIOS POST
Within POST, there are three kinds of messages:
Messages (Power
On Self Test)
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 available.
Because the OmniBook cannot be repaired by a service center below the FRU
level, these messages will provided limited troubleshooting or repair
information. However, the support specialist and service technician will be
able to identify trends in repairs from these codes.
