Patent ID: 8281171

Claim:
A method for adjusting power-saving strategy of a computer system, comprising: determining whether a CPU of the computer system is in a working state by a south bridge chip of the computer system during a power-saving mode of a peripheral device; interrupting the CPU at relatively short intervals to acquire data required for the peripheral device to determine whether or not to execute any task when the CPU is determined to be in the working state; interrupting the CPU and directly restoring the CPU to the working state at relatively long intervals to acquire data required for the peripheral device to determine whether or not to execute any task when the CPU is determined to be not in the working state; and restoring the peripheral device from the power-saving mode when there is a task to be executed; wherein the CPU is interrupted by a timer in a peripheral device controller, and the interrupt intervals of the timer are adjusted by the peripheral device controller according to whether the CPU is in the working state.
