Reassembly Procedure
All Models
 1. Install these components from the old motherboard on the new motherboard: display interface
PCA, speaker assembly (Omnibook 6100 models only), volume PCA, power supply PCA
(Omnibook 6000 models only), CPU module, PCMCIA socket, mini-PCI card #1 (if present), and
mini-PCI card #2 (if present, Omnibook 6100 models only).
  Omnibook 6100: To reattach the display interface PCA to the motherboard, you must first
disconnect the cable that attaches it to the speaker assembly, connect the PCA, then slide the
speaker assembly underneath the PCA and reconnect the cable.
 2. Omnibook 6000 models only: Make sure the SpeedStep power level DIP switches on the
motherboard are set correctly for the CPU. See the note on page 2-20.
 3. Follow the “Reassembly Notes” in the section entitled “Removing the Motherboard or Bottom
Case.”
 4. Store the service ID, serial number, keyboard layout, and display information electronically in the
new motherboard, and reprogram the EEPROM on the new motherboard with the proper settings
for the display—see page 2-31. If the EEPROM is not programmed correctly, the display will not
turn on.

Storing Unit Information Electronically
When replacing a motherboard PCA, you will need to download the Omnibook 6000/6100 service
package from the Partnership Web site (see page vi). This package contains the following:
 · Image for creating a bootable Service Utilities floppy disk.
 · Readme file that explains how to create and use the above floppy disks.
On Omnibook 6000 models, the service utility disk is used to update the EEPROM. If the previous
motherboard was able to boot with the service utility floppy disk, information can be stored onto the
floppy disk so that it can be transferred to the new motherboard. If this information cannot be
transferred, the floppy disk can be used to update the LCD and ESN information manually.
Electronic Serial Number (ESN)
New motherboards should arrive with a default value in the EEPROM for the ESN. This default value
will trigger the unit to ask for the ESN upon the first boot. If the wrong ESN is stored in the new
motherboard’s EEPROM (if you see the wrong ESN on the boot screen or BIOS setup), you must enter
the correct ESN manually by using the service utility disk. You will need to obtain a passcode from a
call center agent to complete this process.
Service Identification Number (Service ID)
The Service ID is a number that corresponds to an encrypted date of purchase so that the warranty
period can be easily determined. If possible, transfer this number from the old motherboard to the new
motherboard using the service utility disk. If transfer is not possible, then no update is needed and the
Service ID should remain “00000” so that a new date is not generated, which could cause confusion.
LCD Settings (Omnibook 6000 models only)
LCD settings int he EEPROM must match the display DIP switch settings on the display interface
PCA. If the settings in these two locations do not match, the display will not work properly. The service
utility disk can update the settings so they match.

Replacing the Bottom Case
Installation Procedure
 1. Install a new Microsoft Product ID label.
 2. Transfer the old serial number label and install a new overlay, or create a new serial number label
using the steps below.
 3. Follow the “Reassembly Notes” on page 2-26.
Installing a New Serial Number Label
Download the latest version of the serial number label template (Microsoft Word format) from the
Partnership Web site (see page vi) under Support/Service in Technical Support Information. Store it
with other Word templates on a PC connected to a laser printer. The latest version includes fields for
warranty period and manufacturing location.
 1. Open a new document based on the serial label template.
 2. Enter the information from the old serial label, and print the new label on plain white paper. The
new label does not have barcodes.
 3. Carefully cut out the new serial label just inside the border and place it into the inner recess in the
bottom case. The bottom of the label goes toward the front of the case.
 4. Ensure that all regulatory labels that appeared on the old bottom case are present on the new
bottom case. This may be accomplished by keeping the old covers, if necessary.
 5. While holding the paper label in place, attach a serial label overlay into the outer recess. It covers
and protects the serial label.

Repairing the BIOS IC
(HP Authorized Service Providers Only)
The BIOS IC of the computer is not replaceable:
 · If the BIOS IC is defective, you must replace the power supply PCA on Omnibook 6000 models or
the motherboard on Omnibook 6100 models.
 · However, if the BIOS IC might only be corrupted, you can attempt to repair it using a Crisis
Recovery floppy—see the information below.
  Note: Reprogramming the BIOS IC
 
A new BIOS IC contains only enough basic programming to boot the Omnibook. After installing a
new power supply PCA, you must reprogram the BIOS IC, preferably with the latest BIOS. You can
download the latest BIOS from the HP Notebook W eb site (see page vi)—follow the directions
provided.
If you do not have a BIOS Crisis Recovery floppy, download the package from the Partnership Web
site (see page vi) under Product Support Information in the Service and Support Library. Follow the
instructions for creating the floppy.
  Caution
 
Make sure you are using the correct BIOS Crisis Recovery floppy for the Omnibook model you are
repairing. The program does not verify the Omnibook model, so you could install the wrong BIOS
image.
 1. Insert the BIOS Crisis Recovery floppy in the floppy drive.
 2. If the computer does not boot from the BIOS Crisis Recovery floppy, try plugging the boot-block
jumper into the Omnibook parallel port, then go to the next step. See the wiring diagram below.
 (In many situations you can skip this step—especially if the computer previously displayed a BIOS
checksum error.)
 3. Turn on the computer and allow it to boot from the floppy disk.
 If the computer does not turn on at all, do the following steps to boot from the floppy disk:
 · Unplug the AC adapter.
 · Press and hold Fn+B.
 · Plug in the AC adapter.
 · Release Fn+B.
 4. Wait while the BIOS is reprogrammed—the display is blank for a minute or more while this
happens.
 If you plugged in a boot block jumper, unplug it before the computer automatically reboots.
 5. After the BIOS is repaired and reprogrammed, check the BIOS version to see whether it is the
latest version. If necessary, reprogram the BIOS IC—see the note at the beginning of this topic.
