Removing the Motherboard or Bottom Case
(HP Authorized Service Providers Only)
Required Equipment
Small Phillips screwdriver.
Small flat-blade screwdriver.
Removal Procedure
Note: Before Replacing the Motherboard
If possible, record the computer's electronic serial number and service ID before you replace the
motherboard. You will then store this information in the EEPROM on the new motherboard using the
Service Utility floppy disk.
1. Download the service package for the Omnibook XT6050 (technology code EF) or Omnibook
XT/VT6200 (technology code EG) from the Partnership web site (see page vi), and create a
Service Utilities floppy disk as described in the package's Readme file.
2. Connect a floppy disk drive module: insert the module into the notebook, or connect it to the
notebook's parallel port using an F2008 external floppy drive cable.
3. Connect an external monitor to the computer, so you can verify the boot process.
4. Plug in an AC adapter.
5. Insert the Service Utilities floppy disk into the floppy drive.
6. Turn on the notebook. When the HP logo appears (on either the built-in display or the external
monitor), press Esc to display the boot menu, then choose Removable Device and boot from the
floppy disk.
7. Select the Serial Number option from the boot menu.
8. When prompted, type A for the automatic update option. This stores the current system data from
the old motherboard on the floppy disk.
1. Unplug the AC adapter, if present, and remove the battery and any secondary battery module.
2. Remove these additional assemblies:
Plug-in module (page 2-5).
Hard disk drive (page 2-7).
Power button panel (page 2-11).
Keyboard (page 2-13).
Heatsink (page 2-15).
Display assembly (page 2-19).
Top case (page 2-21).
3. Remove the five screws that attach the motherboard to the bottom case.
4. From the back of the unit, remove the screw from the LAN/modem PCI panel, and lift the panel
out of the bottom case.
