If replacing the optical drive, disconnect the sensor cable from the optical sensor located on 7.
the underside of the optical drive. Transfer the sensor cable to the replacement drive.
Note: The optical drive sensor can be identied by the presence of resistor R1701. The hard 8.
drive also has a sensor, but it’s resistor is R1700. Note: The optical drive sensor and mounting
bracket will be attached to all replacement optical drives.
