( APM) - A standardized system used by manufacturers of battery-powered computers to control system power management, including shutdown of unused components or of the entire system based on usage patterns. APM can also report the source of system power (AC or battery), the battery status, and the remaining battery life.
An API whose purpose is to monitor and control power supply usage - particularly useful in Laptop computers.
A feature used by some BIOSes in order to make the machine enter a standby state after a given period of inactivity. On laptops, APM is also responsible for reporting the battery status and (if supported) the estimated remaining battery life. ASCII
A software interface (defined by Microsoft and Intel) between hardware-specific power management software (such as that located in a system BIOS) and an operating system power management driver.
n. An application programming interface developed by Microsoft and Intel to monitor and conserve power on a PC-based system, particularly a battery-powered laptop computer, by enabling programs to communicate their power requirements so that the system can route power away from unused hardware components. See also application programming interface. Acronym: APM.
Advanced Power Management (APM) is an API developed by Intel and Microsoft 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.
