A real time clock alarm is a feature that can be used to allow a computer to 'wake up' after shut down to execute tasks every day or on a certain day. It can sometimes be found in the 'Power Management' section of a motherboard's BIOS/UEFI setup. Wake On LAN, Wake on ring, and IPMI functions could also be used to start a computer after it is ...
Active-state power management (ASPM) is a power management mechanism for PCI Express devices to garner power savings while otherwise in a fully active state. Predominantly, this is achieved through active-state link power management; i.e., the PCI Express serial link is powered down when there is no traffic across it.
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 .
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.
Control Panel has been part of Microsoft Windows since Windows 1.0, [1] with each successive version introducing new applets. Beginning with Windows 95, the Control Panel is implemented as a special folder, i.e. the folder does not physically exist, but only contains shortcuts to various applets such as Add or Remove Programs and Internet Options.
Wake-on-Ring (WOR) or Wake-on-Modem (WOM) is a specification that allows supported computers and devices to "wake up" or turn on from a sleeping, hibernating or "soft off" state (e.g. ACPI state G1 or G2), and begin operation.
Hibernation (also known as suspend to disk, or Safe Sleep on Macintosh computers [1]) in computing is powering down a computer while retaining its state.When hibernation begins, the computer saves the contents of its random access memory (RAM) to a hard disk or other non-volatile storage.
Wake-on-LAN can, however, operate across any network in practice, given appropriate configuration and hardware, including remote wake-up across the Internet. In order for Wake-on-LAN to work, parts of the network interface need to stay on. This consumes a small amount of standby power. To further reduce power consumption, the link speed is ...
