ABSTRACT:
A computer system capable of entering a sleep mode is disclosed. The rate at which the computer switches between a normal state and a stop grant state while in the sleep mode is controllable by a timer. The stop grant state is an intermediate power consumption state between the sleep mode and the normal state. The timer may include a software system management interrupt timer. The system may also include processing to determine the cause of the switch from the stop grant state to the normal state.
