3. Press the video-memory upgrade module firmly into the socket, and
pivot the module downward until the module clicks into place.
NOTE: If you do not hear a sharp click when installing the video-memory

4. Replace the expansion-card cage.
5. Replace the computer cover and reconnect the AC power cable to the

video-memory upgrade module and automatically changes the system con-
figuration information in the System Setup program.

Video Memory category. If the total memory is listed incorrectly, repeat
steps 1 through 6 to reseat the video-memory upgrade module and ver-
ify that the computer acknowledges the module.

memory upgrade module.
CAUTION: To avoid possible damage to the video-memory upgrade
socket and/or video-memory upgrade module, the module is keyed and
must be correctly positioned before inserting it into the socket.
