Replacing a memory module
Attention:
Turn off the computer and wait 3 to 5 minutes to let it cool down before
removing the cover.
Note: It may be helpful to place the computer face-down on a soft flat surface
for this procedure. Lenovo recommends that you use a blanket, towel, or
other soft cloth to protect the touch screen from scratches or other damage.
1. Remove any media (disks, CDs, or memory cards) from the drives, shut down
the operating system, and turn off the computer and all attached devices.
2. Unplug all power cords from electrical outlets.
3. Disconnect all cables attached to the computer. This includes power cords,
input/output (I/O) cables, and any other cables that are connected to the
computer. Refer to “Left and right views” and “Rear view” for help with locating
the various connectors.
4. Remove the memory cover as shown.
