Abstract :
During battery operation, the laptop personal computer system power management is an extremely critical design criteria. A device that controls power at differing levels-in the keyboard, the display, as well as in the system´s integrated circuits themselves-is described in this paper. Automatic system turn-on, wake up sequencing, low batter indication, system bus interfacing and other system considerations are also addressed.<>
