Furthermore, a computer system applying the above power management method is also provided.
Claims10
A power management method adapted to a computer system with a main monitor and a host, wherein the computer system operates under different power states, and the power management method comprising:
- determining whether the main monitor is turned off or not;
- when the main monitor is turned off, determining whether to execute a power saving program;
- and
- when the power saving program is determined to be executed, the power of the host is reduced while the computer system is kept in the same power sate.
A computer system, operating under different power states, comprising:
- a main monitor;
- and
- a host with an embedded controller coupled to the main monitor, wherein the embedded controller is used for determining whether the main monitor is turned off or not, and when the embedded controller determines that the main monitor is turned off, the embedded controller determines whether to execute a power saving program, and when the power saving program is determined to be executed, the embedded controller executes a power saving program to reduce the power of the host while the computer system is kept in the same power sate.
