Bi-level power saver method for portable or laptop computer

摘要

A bi-level power saving method for a computer having one level of power saving operations that is executed when the computer is operating on an external power source and another level of power saving operations that is executed when the computer is operating on an internal power source. The method determines whether the computer is operating on an external power source or an internal power source. No preferences for tasks or devices are designated if the computer is operating on an external power source and activity and application have been detected. Various power consuming operations are executed if the computer is operating on an external power source and activity is detected but an application is not detected. The computer powers down devices if the computer is operating on an external power source and no activity is detected. Power saving operations are executed if the computer is operating on an internal power source and activity and application have been detected. Power consuming operations are inhibited if the computer is operating on an internal power source and activity is detected but application is not detected. The operator may override or choose the inhibiting/executing of the power consuming operations.
