Problems solved by technology

[0004] However, the above-mentioned power detection method, due to the limitation of the access method of the monitoring component, makes the operating system unable to tolerate a time delay during the access process. If it is in the access process, the operating system must handle high-priority events In this case, it is easy to cause access errors caused by processing delays, and even wrong battery positioning errors caused by wrong judgments.

Abstract

The present invention is power source detecting architecture and method for hand held information processing device. The present invention can detect the electricity amount in the battery module of hand held information processing device and make the hand held information processing device enter power saving state in case of lower electricity amount. It has processing unit for detecting the residual electricity amount and controlling the work mode of the hand held information processing device based on the residual electricity amount in the battery module.

Description

technical field [0001] The present invention is a structure for detecting power supply, in particular, a structure for detecting the electric capacity of a battery and a detection method thereof applied in a hand-held information processing device. Background technique [0002] Today, with the rapid development of science and technology, information processing devices have developed from indoor to outdoor handheld information processing devices. Handheld information processing devices use a handheld computer as a personal digital assistant. At present The functions of Personal Digital Assistant (PDA) have been developed from basic functions such as calendar, to-do list, notepad, address book, etc. to the present ability to perform synchronous data transmission with computers, and even install various application software. In order to expand its functions, etc., these expansion functions can include: online email sending and receiving functions, stock information browsing fun...
