235 Adding Memory to Your PC Compatibility Card
4 If necessary, disconnect the audio cables from the PC Compatibility Card.
Because the audio cables can be difficult to remove, it’s best to leave them
connected if possible. If you feel you can pull the card out and access the
DIMM slot without disconnecting the audio cables, leave the cables in place.
Otherwise, make a note of where the audio cables are connected so you’ll
know where to reconnect them later. Then grasp the side of each plug and pull
firmly. Be sure to pull the plug, not the cable. It may help to gently rock the
plug from side to side as you pull.
Do not attempt to use pliers to remove these plugs; you may damage the plugs
or your card.
5 Check to see if there is a screw installed on the port fence. If there is, remove it.
6 Check to see if there are levers near the port fence. If there are, press them away from
the port access opening.
7 Grasp the card by its sides and pull it straight out of the slot.
IMPORTANT Do not rock the card side to side as you remove it. Doing so may
break the card or damage the slot.
Gently rock
the plug. Don’t pull on
the cable.
