5.5.2Memory Boards

Memory boards that are in the computer must be removed before others are installed. Memory expansion boards come in two matched boards.To remove the memory boards, complete the following steps:

1.Disconnect the AC power and any external devices (Section 5.3.1).

2.Undock the computer from the auxiliary base if necessary (Section 5.3.2).

3.Remove all battery packs (Section 5.3.3).

4.Remove the memory cover (Section 5.5.1).

CAUTION: If you need to remove the memory expansion boards, be sure to release the locking tabs that secure the memory boards in the slots. If the tabs are not released, the connectors may break and cause irreparable damage to the system board.

5.Release the locking tab 1 at each end of the upper memory board. This releases the memory board and allows it to rotate upwards to ease removal.

6.Lift the free edge of the memory board slightly 2 and pull it straight out of the 3 slot.
