This procedure assumes that you have already performed the
1. Remove all the mounting screws securing the motherboard to the chassis (for screw locations see
motherboard" on page
2. Remove the motherboard from the chassis.
Lift the edge of the motherboard. Make sure that the motherboard connectors clear the chassis while you lift it out of the
chassis. Do not touch the contacts and avoid using excessive force.
IMPORTANT:
During service, avoid using excessive force and always place the motherboard on a grounded, non-metallic, static-free
surface. Never allow any metal to touch the solder contacts on the underside of the motherboard, especially beneath the
battery socket. Improper handling can short-circuit and permanently damage the motherboard.

Replacing the motherboard
IMPORTANT:
Follow the procedures in this section to replace the motherboard. Failure to follow the instructions in this section may corrupt
the system (not easily repaired in the field) or result in an incomplete installation.
■ Troubleshooting cautions
• Before deciding to install a new motherboard, consult (See
• Inspect all cables and internal components as described on
internal components" on page
• If troubleshooting strategies (checking cables and connections, reinstalling system software, and so forth) do not solve the
problem, and you suspect that the hard disk drive or the motherboard is faulty, always troubleshoot in the following order.
IMPORTANT:
Troubleshooting in the wrong order will cause the system to malfunction. In general, it is highly unlikely that both the hard
disk drive and the motherboard are defective; therefore, avoid replacing both to solve one problem.
