CPU heatsink
This section describes how to remove and install a CPU heatsink.
Removing the CPU heatsink
To remove a heatsink:
1. Power down the computer (see
Predisassembly procedures on page 70).
2. Disconnect power from the computer (see
Predisassembly procedures on page 70).
3. Remove the side access panel (see
Removing the side access panel on page 73).
4. Slowly and evenly loosen one pair of diagonally opposite screws (1) from the CPU until the screw
shanks disengage from the system board, and then loosen the remaining pair (2) as shown below.
CAUTION: Do not fully loosen one screw, and then move on to the next. Instead, loosen all
screws a little at a time, ensuring that the CPU remains level.
