Reinstalling the Motherboard
Reassembly Procedure
1.Install the CPU support plate.
2.Insert the I/O connectors through their openings in the bottom case, then lower the motherboard into place.
∙Be careful not to trap the modem or modem/LAN cable(s) under the motherboard (modem and modem/LAN models only).
∙Fit the modem cable through the notch on the edge of the motherboard, and make sure the LAN cable doesn’t block the nearby screw tab.
∙Make sure the alignment posts in the bottom case fit through the holes at the back left and front right corners of the motherboard.
3.Reconnect the cable (modem models only) or cables (modem/LAN models only) at the right rear corner of the motherboard.
When Installing a New Motherboard
After installing a new motherboard, you must electronically transfer to it the serial number and service ID from the previous motherboard.
1.Exit Windows and boot to a DOS prompt:
∙For Windows 98 or ME, press F8 during reboot and select Command Prompt Only.
∙For Windows 2000, boot from a DOS boot floppy disk.
2.Run ESN.EXE from the same source you ran it from when saving the serial number and service ID from the previous motherboard:
∙On a factory software installation, change to the \HP\Drivers\Hputils directory and type esn at the prompt.
∙Otherwise, copy \HP\Drivers\Hputils\Esn.exe from the Recovery CD, then run it on the notebook.
3.Install the serial number and service ID.
∙If you are prompted for the serial number, type the serial number shown on the bottom of the case.
∙If a serial number has already been stored, you must call an HP support center to change it.
