Abstract
A system and method of coordinating power states between two detachable units is disclosed. Only the primary unit has a user-controllable power control. The secondary unit is not directly user controllable. The power states of the two units are coordinated using an actuator mechanism when the units are attached. When the two units are detached, the state of the secondary unit is dependent upon the state of the primary unit and any subsequent commands transmitted by the primary unit to the secondary unit.
Claims20
A method of coordinating power states between two detachable units of an apparatus, comprising:
- when the two units are detached, upon detecting a first change in power status of a primary unit from standby mode to on, transmitting a first command from the primary unit to a secondary unit to turn on;
- and
- when the two units are detached, upon detecting a second change in power status of the primary unit from on to standby mode, transmitting a second command from the primary unit to the secondary unit to go to standby mode.
A system for coordinating power states between two detachable units, comprising:
- means for, when the two units are detached, transmitting a first command from a primary unit to a secondary unit to turn on in response to a first change in power status of the primary unit from standby mode to on;
- and
- means for, when the two units are detached, transmitting a second command from the primary unit to the secondary unit to go to standby mode in response to detecting a second change in power status of the primary unit from on to standby mode.
