Problems solved by technology

The method of using this power saving or sleep mode is nothing more than starting from two aspects of voltage or frequency.
However, just like the quantitative power supply mentioned above, with the complex and powerful functions required by the current laptop computer devices and the corresponding more power consumption, it seems that it is no longer possible to expect to use the existing power saving or sleep mode and other throttling methods to achieve its significant power saving effect

Abstract

The present invention discloses a method for a power control system and power control of a laptop computer device. The power control system consists of an external power supply device, a control unitand a switch unit installed in the laptop device. The external power supply device is removable and provides a DC voltage source with DC voltage value between 5 and 1.8 for the laptop device. The switch unit can switch on or off at least a DC voltage connection of the DC voltage source in the laptop device according to a control signal issued by the control unit.

Description

Technical field [0001] The invention relates to a power management system and a management method for a laptop computer device, and particularly relates to the technical field of controlling an external power device. Background technique [0002] At present, the laptop computer device has made a certain degree of progress and achievements in the design of its battery power management. However, whether it is on the hardware components, software operating system, or driver, even if an optimal power management method can be proposed, the battery life can be extended under the fixed battery power supply. It is also quantitative. [0003] Looking at the current power management methods, most of them allow some temporarily useless components to enter their power saving or sleep mode to save battery power. And to use this kind of power saving or sleep mode method is nothing more than starting from two aspects of voltage or frequency. However, just like the quantitative power supply men...
