Replacing the system board

Important

The heat sink and microprocessor might be very hot. Make sure these

components are cool enough to safely handle before continuing this

procedure.

Note: When replacing the system board you must also order a new retention

module for the new system board or remove the retention module from the

failing system board and install it on the new system board.

This procedure describes how to remove and replace the system board.

1. Open the computer cover. See “Opening the cover” on page 154.

2. Pivot the drive-bay assembly upward to gain access to the heat sink.

3. Remove the hard disk drive and disconnect it from the system board. See

“Replacing the hard disk drive” on page 171.

4. Remove any PCI adapters installed. See “Replacing an adapter card” on page

156.

5. Disconnect all cables connected to the system board. See “System board

connectors” on page 153.

6. Pull up on the blue strap at the front of the system board to release it from

the chassis.
