Installing an Optional Optical Drive

To install an optional optical drive:

1. Turn off the computer properly through the operating system,

then turn off any external devices.

2. Disconnect the power cord from the power outlet and disconnect

any external devices.

3. Remove the computer cover. Refer to “Removing the Computer

Cover.”

4. Install two M3 metric guide screws in the lower holes on each

side of the drive. HP has provided four extra M3 metric guide

screws on the front of the chassis, under the computer cover. The

M3 metric guide screws are silver.

CAUTION: Use only 3/16-inch or 5-mm long screws as guide screws.

Longer screws can damage the internal components of the drive.

✎

When replacing the drive, transfer the four M3 metric guide screws

from the old drive to the new one. The screws take the place of drive

rails.
