System and method for detection of an accessory device connection status
First Claim
1. A method for operating a portable computing device, the method comprising:
- coupling a signal line accessible through an outlet of the portable computing device to a communication device;
detecting a signal on the signal line to determine whether the communication device is actively connected to a portable computing device; and
suspending execution of a programmed event that was to occur at a subsequent moment in time in order to reduce power consumption of the portable computing device.

Abstract
Embodiments of this invention provide for a portable computer that determines whether an accessory device is actively connected to it. In one embodiment, the portable computer may include a signal line accessible through an output of the portable computing device. The signal line may be connected to a communication device such as a communication cradle. The portable computer may detect a signal on the signal line to determine whether the communication device is actively connected to the portable computer. If the communication device is actively connected, the portable computer suspends implementation of a time-out feature that would otherwise reduce power consumption of the portable computer.

12. A detachable assembly, comprising:
-
a communication device; and
a portable computing device adapted that is detachably coupleable to the communication device, the portable computing device including;
a signal line that is adapted to couple to an output node of the communication device; and
a processor coupled to the signal line, wherein the processor is configured to determine when the communication device is actively connected to the portable computing device;
wherein the processor is programmed to suspend execution of a programmed event that would have otherwise occurred at a susbequent moment in time in order to reduce power consumption of the portable computing device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
