Removal Procedure
Note: Before Replacing the Motherboard
If possible, record the computer’s electronic serial number before you replace the motherboard. You
will then store the electronic serial number in the EEPROM on the new motherboard using the Service
Utility floppy disk.
1. Download the service package for the Omnibook XE4100 (technology code KC) or Omnibook
XE4500 (technology code KB) from the Partnership web site (see page vii), and create a Service
Utilities floppy disk as described in the package’s Readme file.
2. Plug in an AC adapter.
3. Insert the Service Utilities floppy disk in the floppy drive.
4. 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.
5. Select the Serial Number option from the boot menu.
6. When prompted, type A for the automatic update option. This stores the current system data from
the old motherboard on the floppy disk.
