The OB4000 DSTN may report the display RAM to be 1024KBs, however, it is
512KB. Later versions have corrected this. It is not a hardware problem but a
reporting problem.

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.
TFT Display
Quality
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:
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.
___________

Download from Www.Somanuals.com. All Manuals Search And Download.
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.
Keyboard: 85-key touch-type keyboard with embedded numeric keypad and 12

Battery life can be doubled by installing second battery in place of the 3.5 "
flexible drive. The OmniBook will recognize the additional battery and provide
battery status of both batteries (can be installed hot).
Smart Battery: The OmniBook 4000 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 4000 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
System password: When the password setting is enabled, a window will pop-up
to allow the user to enter the old password, enter a new password and to verify
the new
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:
Password
Decode
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.
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.
Password
Decode Policy
In addition to protecting the program itself, it's use is also controlled. Hewlett-
Pakard 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.

Installing memory
(End User Replaceable)
The OmniBook 4000 family has two memory locations for expanding system RAM.
The memory location on the side of the OmniBook that has the battery also has the
factory RAM module installed. To add an additional 8MB or 16MB of RAM, use the
location on the other side of the unit near the floppy drive. If the base unit has
4MB or 8MB of memory, and you want to expand the memory to more than 20MB
or 24MB, then the original 4MB or 8MB module must be replace with a larger
module.

either side of the display line up parallel with their slots in the top case. If they are
not parallel, the post will get caught inside the top case before the display is seated
completely. If this happens, remove the display and line the posts up properly.
Also take care that the Icon Assembly flex cable is tucked inside of the “tunnel” of
the Icon Assembly. This will prevent the cable from crimping and possibly
malfunctioning.

The Enhanced Port Replicator (EPR) for the OmniBook 4000 contains no field
replaceable components. If any component of the EPR is defective, the entire unit
must be replaced.
Troubleshooting Tips:
·
·
·
The OmniBook 4000 will only detect one pointing device at a time. Therefore, if
an external mouse is connected to the EPR, the track ball will not be active.
When an external mouse is detached, the pointing devices settings must be
manually updated in the Setup for the change to be detected.
The EPR PCMCIA slots do not receive power when the OmniBook is in Suspend

Troubleshooting and Repair
The OmniBook 4000C and CT will not charge the batteries while in "ON"
mode.
Known Hardware
Issues
Certain HP Vectra PCs will not link over I/R with the OB 4000. Refer to the
technical newsletter for details.
The complete self-test procedure is documented in the OmniBook 4000
Operating Guide.
OmniBook Self-
Test
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 4000 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:
First POST:
BEEP CODES
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.

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:
Last POST:
DISPLAY CODES
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

If the unit still fails to boot, it requires service.
NOTE: make sure the display is adjusted to be visible.
Within POST, there are three kinds of messages:
PhoenixBIOS
POST 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 infon-nation 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.
