Power saving control device and method for notebook computer

Abstract

The invention relates to a power saving control device for a notebook computer, which is used for saving the power of the notebook computer by controlling the working state of a wireless communication module and which comprises: an antenna enabling closing unit, a switch circuit and a switch circuit switching-off unit, wherein the antenna enabling closing unit is connected with the wireless communication module and used for sending an antenna enabling closing signal to the wireless communication module upon the reception of a wireless communication module closing signal from a shortcut key inorder to close antenna enabling; the switch circuit is arranged on a power supply line of the wireless communication module and used for switching on or off the power supply line of the wireless communication module; and the switch circuit switching-off unit is connected with the switch circuit and used for sending a power supply line switching-off signal to the switch circuit after the antenna enabling is closed. The invention further discloses a corresponding power saving control method for the notebook computer. With the help of the power saving control device disclosed in the invention, the wireless communication module is in a state of completely no power consumption after being closed, thereby realizing the effect of saving more power of the notebook computer in case that the wireless communication module is closed.

Description

technical field [0001] The invention relates to a notebook computer power saving technology, in particular to a notebook computer power saving control device and method. Background technique [0002] The wireless communication module of the notebook computer is one of the main power consumption units of the notebook computer under working condition. Notebook computers in the prior art are generally equipped with shortcut keys for disabling the wireless communication function, including keyboard shortcut keys or dial switches. When the user does not need to use the wireless communication function, the user can turn off the wireless communication module through the shortcut key, which can save power. [0003] However, the inventor found in the process of implementing the present invention that the shortcut keys in the prior art only turn off the antenna transmitting and receiving functions of the wireless communication module, but do not turn off the power supply of the wirel...
