Abstract
A system for managing power levels for a general purpose computer having a standby and a full-power mode of operation provides apparatus and a method for monitoring times of user input and control routines for using the times of user input to calculate optimum times for initiating full power operation and standby mode. The control routines are configured to provide the optimum times to a real time clock that remains powered in the standby mode, which triggers switching elements to initiate full power and standby mode. In one embodiment of the system, startup and standby may be initiated either by user input or automatically by the power management system. Startup and standby initiation times may be different for different days and time periods based on both preprogrammed and calculated values.
