Removing the rear cover

Note:

Turn off the computer and wait 3 to 5 minutes to let it cool down before removing the rear 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.

To remove the rear cover:

Step 1.

Remove any media (disks, CDs, DVDs, or memory cards) from the drives, shut down the operating
system, and turn off the computer and all attached devices.

Step 2.

Unplug all power cords from electrical outlets.

Step 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 view”
and “Rear view” for help with locating the various connectors.
