Embodiment Construction

[0028] figure 1 It is a flow chart of detecting battery status in the present invention, as shown in the figure:

[0029] Step 101, firstly, detect the current working state of the battery (such as: output voltage value, output current value, body temperature, etc.) of the battery and read the working state corresponding to the operation of the battery by a basic input and output system unit;

[0030] Step 103, if the working state does not meet the battery electrical standard, then send a warning message to the display unit (such as: screen or indicator light) of the system device, for example: a text message of "battery damage" is displayed on the screen to indicate that the battery Damaged and unusable, then go to step 109 to end the test;

[0031] Step 102, on the contrary, if the working state of the battery in step 101 is normal (i.e. conforms to the electrical standard of the battery), then send a status message corresponding to the normal working state of the battery ...

Abstract

A method and its device for automatically detecting the state of battery in notebook computer and controlling the charging and discharging of the said battery feature that a BIOS unit is used to control the first and the second controller for controlling the charging and discharging of battery and detecting the state and capacity of battery, so determining the performance of battery. Its advantages are instantameous detecting on-line, power supply norral operation and no need to spend time of battery detection.

Description

(1) Technical field [0001] The invention relates to an automatic detection of a battery, in particular to a method for testing whether a battery supplying power can operate normally and effectively in a notebook computer. (2) Background technology [0002] The battery is one of the important components of all portable electronic products. The performance of the battery often directly affects the convenience of electronic products, especially in notebook computers. A battery with a long cycle life is used as a power source, and the function of the notebook computer is bound to be greatly reduced. In the production process of traditional notebook computers, because there is no step for battery function design and detection, it is often only charged to the battery in the notebook computer until it is fully charged, which is regarded as the completion of the charging step, but this Whether the battery placed in the notebook computer is 100% fully charged, or its capacity is ins...
