Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] As shown in FIG. 1 , the computer power management device of the present invention includes: a detection unit, a judging unit, and a computer control unit. Wherein, the detection unit is used to detect whether the user is located in front of the computer, and sends the detection result to the judging unit; , sending a corresponding control signal to the computer control unit; the computer control unit is used to receive the control signal sent by the judging unit, and only when the control signal is an effective control signal, perform corresponding operations on the computer so that the computer enters the user setting specific power management mode.

[0020] The execution process of the computer power management device of the present invention is:

[0021] Step 101, the detection unit detects whether the user is in front of the computer, and sends the dete...

Abstract

The invention also provides a computer power source management device and method. The device includes detection element, decision element, and computer control element. The detection element detects the user is in front of computer or not, and the detection result is sent to the decision element; and the decision element is used to obtain the state of operation system, and the relative control signal is sent to the computer control element according to operation system state and the user's state from the detection element; and said computer control element is used to receive the control signal form the decision element, when the control signal is effective signal, the computer will do relative operation, and the computer enters the power source management mode set by the user. The device and method of invention can make the user operate the computer, and reduce the power consumption at the same time.

Description

technical field [0001] The invention relates to the field of computers, in particular to a computer power management device and method. Background technique [0002] The power management mode of the existing computer is: no matter whether the user is in place, that is, whether it is in front of the computer, it will detect whether the operating system is in an idle state at a specified point in time, and if the operating system is in an idle state at this point in time, It will enter the corresponding power saving mode, such as entering standby state or hibernation state. When the set detection time interval is relatively short, and the user does not operate the computer temporarily, but the computer enters the corresponding power-saving mode, the user must wake up the system again, causing some inconvenience in use; or when the set detection time interval Relatively long, when the user has been away from the computer for a long time, and the operating system has been in an...
