a. TO REMOVE THE MOTHERBOARD
1. If you are replacing the motherboard with a new motherboard, remove the following
from the motherboard:
• DIMM (page 4-29)
• CPU (page 4-30)
• BIOS chip
• CD-ROM drive ribbon cable (see F04-301-01 on page 4-10)
2. Remove the 5 mounting screws on the motherboard (see F04-402-01 on page 4-23 for
screw locations).
3. Lift the edge of the motherboard opposite the back panel connectors to remove the
motherboard from the chassis (see F04-402-02 on page 4-25).
Two snap-top standoffs on the base of the chassis also help to hold the motherboard in
place. Gently pull up on the motherboard to release it from the standoffs.
Make sure the back panel connectors on the motherboard clear the chassis as you re-
move the board. Avoid handling contacts and using excessive force.
