Abstract
A power saving method for an optical disk drive of a rugged electronic device is described. In the method, whether a watertight lid outside the optical disk drive is in open/closed state is detected by a sensor. When the watertight lid is in the closed state, whether an optical disk exists in the optical disk drive is detected by a read/write head of the optical disk drive. When no optical disk exists, a controller in the rugged electronic device begins to time. When a predetermined time is reached and no optical disk drive start command is received, the controller turns off an electrical connection between a power supply and the optical disk drive. When an optical disk drive start command is received, the controller enables the electrical connection between the power supply and the optical disk drive.
