Abstract
A Power Management driver employed within an APM system of a computer system including an operating system driver ('APM driver') and a Basic Input/Output System ('APM BIOS'). The Power Management driver, operating in conjunction with the operating system, intercepts APM messages intended to be transferred from the APM driver to the APM BIOS in order to reduce power applied to a plurality of power manageable hardware devices. After intercepting the APM message and determining that power manageable hardware devices are ready to be powered-down, the Power Management driver issues a number of APM messages to the APM BIOS to sequentially power-down the power manageable hardware devices instead of just acknowledging a previously transmitted APM message from the APM BIOS. This allows the CPU to service network interrupt queries and time scheduled events.
