Abstract

The invention provides a laptop with a power failure protection module, and relates to the technical field of computers. The laptop comprises an adaptor, a battery charging-discharging module and a laptop main board. The laptop has the structural characteristics that the laptop also comprises the power failure protection module consisting of a control circuit, a charging circuit, a farad-class energy storage capacitor and a discharging circuit which are connected in series in sequence. By the adaptor, the commercial power supplies direct voltage to power a power supply mode detection circuit in the laptop main board and simultaneously charges the battery charging-discharging module and the power failure protection module; and the outputs of the battery charging-discharging module and the power failure protection module are connected with the power supply mode detection circuit respectively. Compared with the prior art, the battery charging-discharging module can be replaced without being powered off, simultaneously avoid the influences on the normal work of a user due to power failure and provide the high-quality power for the computer system.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a notebook computer which can work without power supply when replacing a battery charging and discharging module. Background technique [0002] The three-cell battery used in the notebook computer has a power supply time of only about 3 hours, which is very inconvenient for some business people to go out to work. Therefore, many notebook computer manufacturers have begun to produce dual-battery notebook computers, providing three-cell batteries and spare six-cell batteries, and the use time can be as long as about ten hours, which is favored by business people. In the prior art, the dual batteries need to be replaced when the computer is turned off, and restarting the computer after battery replacement brings inconvenience to the user; in addition, some users may mistakenly unplug the battery of the notebook computer when it is charged, which may damage the data that the user i...
