To remove the system board, complete the following steps:
1. Remove the access panel (Section 6.6.1).

the system board connector as that will erase the CMOS. Remove the external battery from the
hook-and-loop fastener on the chassis but leave it electrically connected to the system board.
3. Disconnect any cables attached to the system board.
CAUTION: If memory has been upgraded with a DIMM taller than 1.25 inches (3.2-cm) in the memory socket
closest to the edge of the board, the DIMM must be removed prior to removing the system board to prevent
damaging the DIMM, the DIMM socket, or the system board. It is not necessary to remove the system board in
order to remove or install the DIMMs.
4. Remove any DIMMs installed on the system board (Section 6.12.1).
