2-58 Removal and Replacement Service Manual
21. Remove the following components from the old motherboard, and then install onto the new
motherboard:
•
CPU module
• Wireless LAN Mini PCI card (if present)
• SDRAM modules
22. Follow the reassembly notes in the section entitled “Removing the Motherboard” on page 2-50.
NOTE: After Replacing the Motherboard
If present, insert the modem port cover into the modem port opening. Afterwards, you must use
the Service Utility floppy disk to store the system data and display information in the EEPROM on the
new motherboard. To do so:
1. Plug in an AC adapter.
2. Insert the Service Utilities floppy disk in the floppy drive.
3. Turn on the notebook.
4. If you hear 5 beeps, press F1 to update the display data stored on the motherboard. Let the notebook
reboot, and then go to the next step.
5. Select the Serial Number option from the boot menu.
6. If you successfully stored system data on the floppy disk before removing the old motherboard,
type A for the automatic update. This restores the old system data on the new motherboard.
If you did not store system data, type M for the manual update option. Enter the serial number from the
bottom of the notebook—you might have to contact an HP support center to do this.
