Claim:
1. A method of coordinating power states between two detachable units of an apparatus, the two detachable units including a primary unit and a secondary unit, the method comprising: when the two detachable units have an attached state, coordinating the power states of the primary unit and the secondary unit between a standby mode and an on mode by moving a first movable element on the primary unit between first and second positions, wherein the first movable element is coupled to a second movable element on the secondary unit such that movement of the first movable element causes the second movable element on the secondary unit to move between corresponding first and second positions, wherein the second movable element is moved between the corresponding first and second positions without the secondary unit receiving digital or analog signals from the primary unit to cause the movement of the second movable element; and when the two detachable units have a detached state, activating a transceiver of the secondary unit and coordinating the power states of the primary unit and the secondary unit between the standby mode and the on mode using a first communication link that includes the activated transceiver.
