'''Power management''' is a feature of some electrical appliances, especially [[photocopying|copiers]], [[computer]]s, computer [[CPU]]s, computer [[GPU]]s and computer [[peripheral]]s such as [[Computer monitor|monitors]] and [[Computer printer|printers]], that turns off the power or switches the system to a low-power state when inactive. In computing this is known as [[PC power management]] and is built around a standard called [[Advanced Configuration and Power Interface|ACPI]] which superseded
[[advanced power management|APM]]. All recent computers have ACPI support.
