Removing the base cover

Note: Turn off the computer and wait 3 to 5 minutes to let it cool down before removing the base 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 computer screen from scratches
or other damage.

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.
Step 4. Place the computer face-down on a soft flat surface, then remove the 7 screws that secure the
base cover to the base.
Step 5. Return the computer to an upright position, then lift up the base cover and slide it out as shown.
