: This procedure assumes that you have already performed the procedure “To remove
boards and cables from the motherboard” on page 55 .
1 Remove the hard disk drive bracket, with hard disk drive attached (see page 77 ).
Remove the screw that attaches the bracket to the shelf. Removing the hard disk drive and
hard disk drive bracket provides the clearance necessary for removing the motherboard. You
must also detach the hard disk drive power cable to remove the hard disk drive.
2 If the DVI port cover is attached to the connector panel, remove the two mounting screws and
remove the DVI port cover.
3 Remove all the mounting screws securing the motherboard to the chassis (for screw locations,
see page 53 ).
4 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.
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.
