Abstract

The present invention provides a method for setting a power management status of a device and a power-saving method of the device, applied for a computer system complying with ACPI specification. The methods include steps of: providing a PMU module, which can realize various power management statuses of a CPU in the computer system; and setting an identifying signal for controlling a power management status of the device corresponding to the specific power management status realized by the PMU module. The device used with the computer system can enter different power management statuses in response to the identifying signal so as to reduce the power consumption of the computer system in operation.
