● To remove the motherboard
NOTE:
This procedure assumes that you have already performed the procedure “Shutting down the system” on page 33 .
1. Remove all the mounting screws securing the motherboard to the chassis (for screw locations see “Removing the
motherboard” on page 42 ).
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.
3. If you are replacing the motherboard with a new motherboard, remove the following from the old motherboard:
• DIMM (See “DIMMs” on page 48 )
• CPU (See “CPU” on page 49 )
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 “Troubleshooting” on page 85 ).
• Inspect all cables and internal components as described on “Checking external connections” on page 85 and “Checking
internal components” on page 85 .
• 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.
