Abstract
Official abstract text for this publication.
A power management method and an electronic system using the same are provided. The electronic system includes a display device and an auxiliary device, and has dual batteries and two subsystems. By detection and control mechanisms of the subsystems, the electronic system may allow the display device to maintain in a full power state, in the case where the external power is available or the power of the auxiliary device is sufficient. On the other hand, the auxiliary device may apply to the display device, such as a notebook computer, and the battery time may also be extended since the computer has two batteries.
First claim
Opening claim text (preview).
What is claimed is: 1. An electronic system with power management, comprising: a display device comprising: a first battery; a connection port; a first subsystem; a first switch connected to the connection port and the first subsystem; a first charge circuit connected to the first switch and the first battery; and a second switch connected to the first switch and the first battery; and an auxiliary device comprising a second battery; a socket; a second subsystem…
