Abstract

A method for controlling power supply of radio local area network for portable computer includes confirming whether network is applied to be used by user or not when radio local area network card is at on state, controlling south bridge to switch on power supply switch of said network by computer basic I / O system if it is, utilizing said power supply switch to supply power on said network through PCI connector, confirming whether network is used by user or not and switching off power supply switch if network is not used by user.

Description

technical field [0001] The present invention relates to portable computers, and more specifically, to a wireless LAN power control device and method for portable computers that can automatically turn on / off the power supplied to a wireless local area network according to whether a user uses the wireless local area network. Background technique [0002] Recently developed portable computers are equipped with wireless local area networks, a network that enables computer communication by using radio waves or ultraviolet rays instead of cables. Each computer is wirelessly connected to each base station called an access point (AP), and is connected to a wired network or the Internet through it. It has the following advantages: the computer at home can be wirelessly connected to the network, and if you have a wireless network ID, you can connect your notebook computer to the Internet in any wireless local area network service area in the city. [0003] figure 1 It is a schematic...
