Reassembly Note

Reinstall the motherboard in the unit following the “Reassembly Notes” on page 2-26.

Note: After Replacing the Motherboard

After replacing the motherboard, you must use the Service Utility floppy disk to store the system data and display information in the EEPROM on the new motherboard.

1.Connect a floppy disk drive to the computer using a USB floppy cable, or dock the computer and insert a floppy drive module into the expansion base.

2.Plug in an AC adapter.

3.Insert the Service Utilities floppy disk in the floppy drive.

4.Turn on the computer.

5.If you hear 5 beeps, press F1 to update the display data stored on the motherboard. Let the computer reboot and go to the next step.

6.Select the Serial Number option from the boot menu.

7.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 unit—you may have to contact an HP support center to do this.
