ABSTRACT:
A method and device for executing battery auto-learning applied to a portable data processor with a rechargeable battery and a current gauge is disclosed. The device includes a charging device, a first switch and a second switch controlled by the portable data processor. The notebook computer can control the first switch, the second switch and the charging device automatically so that the battery learning process can be executed automatically instead of being operated manually. It can save a lot of manufacturing cost and time. Moreover, if the user wants to eliminate the memory effect of the rechargeable battery, he can set the executing times for executing the battery auto-learning to achieve the purpose.
