To replace the optical drive
Note
For this procedure, it helps to place the computer face-down on a
soft flat surface. Lenovo recommends that you use a blanket, towel,
or other soft cloth to protect the screen surface from scratches or
other damage.
1. Remove any media (diskettes, CDs, or memory cards) from the drives,
shut down the operating system, turn off all attached devices, and the
computer.
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 “Locating connectors on the rear
of the computer”.
4. Remove the rubber cap that protects the screw.
5. Remove the screw that secures the optical drive to the chassis.
6. Slide the optical drive out of the drive bay.
