Embodiment
Radio local network power supply control device and control method to portable computer among the present invention is described in detail as follows below with reference to accompanying drawings.
Fig. 2 is the formation synoptic diagram of embodiment of the radio local network power supply control device of portable computer of the present invention.
As shown in Figure 2, whether the radio local network power supply control device of portable computer is made of following components: on computer operating system (O/S) 30, can use network to carry out the basic input output system of computer (system BIOS) 31 of sensing to the user; Be connected with PCI connector 38 by pci interface, utilize the GPO interface that moves by aforementioned calculation machine Basic Input or Output System (BIOS) 31, export the south bridge 36 of high/low signal; According to the high/low signal of above-mentioned south bridge 36 outputs, the wireless local network source of WLAN (wireless local area network) power suppling part 42 supplies is carried out the switch 44 that opening/closing switches; By above-mentioned switch 44, receive the wireless local network source, according to the wireless local network source that receives, the PCI connector 38 of opening/closing wireless LAN card 40.
Below with reference to accompanying drawings the radio local network power supply control device of portable computer of the present invention and the embodiment of method are elaborated.
At first, when computer operating system 30 is in the state of regular event, wireless LAN card 40 is in the state of closing initial stage power supply supply.
At this moment, on computer operating system, when the user asked to use network, for example, when the user clicked the WEB browser, basic input output system of computer 31 carried out sensing to it.
At this moment, aforementioned calculation machine Basic Input or Output System (BIOS) 31 transmit control signal to south bridge 36, and south bridge 36 is controlled to the opening/closing of switch 44 to switch 44 output height or low signals according to the network operating position that senses.
Here, south bridge is connected with PCI connector 38 by pci interface, and the GPO interface by inside is connected with switch 44, and by the GPO interface, to the high/low signal of switch 44 outputs.According to above-mentioned high/low signal, off/on switches 44, thus be switched on or switched off the wireless local network source that WLAN (wireless local area network) power suppling part 42 is supplied.
Therefore, if the user proposes network connecting request, switch 44 is opened, and to PCI connector 38 provisioning wireless LAN (Local Area Network) power supplys, PCI connector 38 is to wireless LAN card 40 power supplies, and makes its operation.
And, according to user's network connecting request,, connect to base station request network by central processing unit 32, north bridge 34, south bridge 36, PCI connector 38, wireless LAN card 40, realize wireless connections.
When the user does not use network, promptly, web browser window is closed or when certain hour does not use web browser (system standby pattern), basic input output system of computer 31 senses this situation, and the result that will sense sends south bridge 36 to, and south bridge 36 is by the PGO interface, the output low signal, off switch 44 disconnects the wireless local network source to 38 supplies of PCI connector.
Therefore, by disconnecting wireless local network source, close wireless LAN card 40 to 38 supplies of PCI connector.
Fig. 3 is the process flow diagram of embodiment of the WLAN (wireless local area network) power control method of portable computer among the present invention.
As shown in Figure 3, the flow process of the WLAN (wireless local area network) power control method of portable computer is as follows: if system supply power supply (S30), the computer operating system regular event.At this moment, wireless LAN card is in closed condition.
Then, on computer operating system, confirm whether the user proposes network and use request (S32), if the user has proposed the use network requests, basic input output system of computer carries out sensing (S34) to it, and control south bridge (S36).
In order to open switch, above-mentioned south bridge is exported high signal to the GPO interface, according to the high signal of GPO interface output, and switch opens, normally (S40) to WLAN (wireless local area network) power supply (S38).At this moment, the WLAN (wireless local area network) power suppling part is to switch, PCI connector and wireless LAN card provisioning wireless LAN (Local Area Network) power supply.
Therefore, finish wireless connections, be connected on the webpage of user's request by wireless LAN card.
Then, confirm whether the user uses network (S42), if the user does not use network, for disconnection of wireless LAN (Local Area Network) power supply, off switch (S44).
Like this, whether use network, can automatically control power supply, can reach the minimizing consumption of cell power supply, prolong the battery effect in serviceable life to the WLAN (wireless local area network) supply according to the user.
By above-mentioned description, relevant speciality personnel can carry out various change and modification fully in the scope that does not depart from the technology of the present invention thought.Therefore, the technical scope of this invention is not limited to the content on the instructions, must determine its technical scope according to interest field.
