Abstract

A notebook computer comprises a mainboard, a battery and an overboard direct-current power interface. The mainboard is provided with a power input end. The notebook computer further comprises a first switch and a second switch. The battery is connected to the direct-current power interface through the first switch. The power input end of the mainboard is connected to the battery through the second switch. According to the working modes of the first switch and the second switch, when the computer receives a power enabled instruction, the first switch is turned on, and the second switch is turned on; when the computer receives a power stop instruction, the first switch is turned off immediately, the mainboard begins to reset, and the second switch is turned off after the mainboard is reset. According to the design, the battery cannot be in the fully-charged state for a long time after the computer is stopped, so that the service life of the battery is greatly prolonged; compared with the prior art, the higher charging level is achieved, a circuit is simpler, control is easier, and electric energy is saved.

Description

technical field [0001] The invention relates to a notebook computer, in particular to the connection and control of its battery, which can belong to G06F1 / 26 in the international patent classification table. Background technique [0002] For notebook computers, the battery used as the internal power supply of the whole machine has always had a lifespan problem when it is not connected to an external power supply. The industry has been working hard to improve its lifespan, but the designs of the prior art are all complicated and the effect is still not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a notebook computer, which can significantly prolong the battery life of the notebook computer, and the improved structure is relatively simple, low in cost and energy-saving. [0004] The technical solution of the present invention to solve the technical problem is that a notebook computer includes a main board,...
