Advanced power management (APM) is an API developed by Intel and Microsoft and released in 1992[1] which enables an operating system running an IBM-compatible personal computer to work with the BIOS (part of the computer's firmware) to achieve power management.

Revision 1.2 was the last version of the APM specification, released in 1996. ACPI is intended as the successor to APM. Microsoft dropped support for APM in Windows Vista. The Linux kernel still mostly supports APM, with the last fully functional APM support shipping in 3.3.
