ABSTRACT:
An optical drive may include drive electronics and wake circuitry. The drive electronics may be arranged to operate the optical drive when in a powered mode. The wake circuitry may be arranged to generate a wake signal when the drive electronics are in an unpowered mode and when a button is pushed on the optical drive or optical media is inserted into the drive. An interface to the optical drive may include a line to carry the wake signal from the wake circuitry. A host may house the optical drive and communicate with optical drive via the interface.
