other damage.

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