Remove the following components from the old motherboard and install onto the new
motherboard:
• CPU module
• Wireless LAN mini-PCI card (if present)
• SDRAM modules
Follow the reassembly notes in the section entitled “Removing the Motherboard” on page 2-32.
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 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.
