  • Computer power management system
    Patent number: 5560024
    Abstract: A low power management system including both hardware and software is provided for a battery powered portable computer. The low power management system powers down various sections of the computer when they are not used. The low power management system is controlled by a control program in the microprocessor of the computer. The low power management system includes the capability to turn off clock signals to various sections of the computer based upon demand. Also included is the capability to turn on clock signals based upon demand. The low power management system also includes the capability to turn on the computer upon a press of a key on the computer keyboard. The low power management system monitors software application programs for keyboard activity so as to turn off the microprocessor in the computer in response to a loop looking for a keypress and certain other loops which can be monitored without use of the microprocessor.
