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 notebook service package 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, and 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.
1. Unplug the AC adapter, if present, and then remove the battery.
