Replacing the optical drive

Attention: Turn off the computer and wait 3 to 5 minutes to let it cool

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.

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,
