Patent ID: 7065660

Claim:
A computer comprising a power management control module, a manually operable switch, and a power control module wherein a current state of the computer comprises a power on state and a power off state, the power management control module being operable to receive a first input and a second input, the first input corresponding to the current state, the second input comprising a request signal received from the manually operable switch and corresponding to a requested state, the requested signal having a time duration, wherein a request signal corresponding to the power off state has a time duration that is different from that of a request signal corresponding to the power on state, generate an output comprising a single pulse when the requested state is different from the current state, cause no change in the output when the request signal corresponds to the power on state and when the computer is in the power on state, and generate an output having two pulses when the computer is in the power off state and when the requested state is the power off state, wherein the power control module is responsive to the output to cause a transition between the power on state and the power off state.
