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.
