Windows 98, Windows 98 Second Edition, Windows Millennium Edition, Windows 2000 and Windows XP support two forms of power management.

APM 1.2, the last APM standard, is a a BIOS-based scheme of system power management. It provides CPU and device power management and uses device activity timeouts to determine when to transition devices to low power states.
Unfortunately, APM has a number of problems associated with it.
