Problems solved by technology

However, since the battery-powered computer system 100 is mostly a handheld device with a small size, it cannot provide a large circuit board area.
However, the computer system 100 with more embedded controllers 106 must occupy a larger circuit board area, which is not conducive to the reduction of its volume.
Secondly, the embedded controller 106 controlling the system management bus 110 also has a relatively high hardware circuit cost

Embodiment Construction

[0034] image 3 Is a block diagram of a battery powered computer system 300 according to the present invention. In one embodiment, the computer system 300 is a notebook computer or a handheld device. The computer system 300 includes a controller 302 , a South Bridge Chipset (South Bridge Chipset) 304 , a System Management Bus (System Management Bus) 310 , a battery device 308 , and other devices 312 . The controller 302 is the core of the computer system 300 and manages other member devices of the computer system 300 . The battery device 308 supplies power for each member device in the computer system to operate. South bridge chipset 304 is connected to battery device 308 and other devices 312 through system management bus 310 . In one embodiment, the SMB clock pin and the SMB data pin of the south bridge chipset 304 are respectively connected to the SMB clock pin and the SMB data pin of the battery device 308 via the SMB 310 . In addition, the south bridge chipset 304 ha...

Abstract

The invention provides a battery control and management method for a computer system. In an embodiment, the computer system comprises a controller, a south bridge chipsetíí(South Bridge Chipset) and a battery device, and the battery device is connected to the south bridge chipset through a system management bus(System Management Bus). Firstly, a timer of the south bridge chipset is used for cumulative time; and then when the cumulative value of the timer is more than the scheduled time value, the south bridge chipset is controlled to send system control interruption to the controller; finally, when the controller receives the system control interruption, the controller captures electricity quantity data of the battery device through the system management bus.

Description

technical field [0001] The present invention relates to computer systems, in particular to battery control for computer systems. Background technique [0002] Computer systems, such as handheld devices or notebook computers, operate on battery power. Since the power supply of the battery is limited, when the power of the battery is exhausted, the computer system cannot continue to work. Therefore, this type of computer system needs to know the power of the battery at any time, so as to always reflect the current remaining power of the battery to the user, so that the user can replace the battery before the battery is exhausted, so as to maintain the operation of the computer system. [0003] figure 1 is a block diagram of a known battery powered computer system 100 . The computer system 100 includes a controller 102 , a South Bridge Chipset 104 , an Embedded Controller 106 , a System Management Bus 110 , a battery device 108 , and other devices 112 . The controller 102 i...
