Sleep mode (or suspend to RAM) is a low power mode for electronic devices such as computers, televisions, and remote controlled devices. These modes save significantly on electrical consumption compared to leaving a device fully on and, upon resume, allow the user to avoid having to reissue instructions or to wait for a machine to boot .
APM defines five power states for the computer system: Full On: The computer is powered on, and no devices are in a power saving mode. APM Enabled: The computer is powered on, and APM is controlling device power management as needed. APM Standby: Most devices are in their low-power state, the CPU is slowed or stopped, and the system state is saved.
This is usually managed by the operating system's power management software or through the BIOS, thus different settings can be configured for laptop battery mode versus running from the battery charger. Low power mode is often achieved by reducing or even stopping the serial bus clock as well as possibly powering down the PHY device itself.
Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring. It was first released in ...
Unused features may be disabled in the computer's BIOS setup to save power. Devices were introduced in 2010 that allow the remote controller for equipment to be used to totally switch off power to everything plugged into a power strip. It was claimed in the UK that this could save £30, more than the price of the device, in one year. [33]
A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [ 1 ] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.
