  2. VESA Display Power Management Signaling - Wikipedia

    en.wikipedia.org/wiki/VESA_Display_Power...

    By the late 1990s, most new monitors implemented at least one DPMS level. [citation needed]DPMS does not define implementation details of its various power levels; [3] while in a CRT-based display the three steps could logically be mapped to three blocks to be shut down in order of increasing savings, thermal stress, and warm-up time (video amplifier, deflection, filaments) not all designs ...

  3. Standby power - Wikipedia

    en.wikipedia.org/wiki/Standby_power

    Standby power consumption can be reduced by unplugging or totally switching off, if possible, devices with a standby mode not currently in use; if several devices are used together or only when a room is occupied, they can be connected to a single power strip that is switched off when not needed. This may cause some electronic devices ...

  4. Sleep mode - Wikipedia

    en.wikipedia.org/wiki/Sleep_mode

    A sleeping PC is on standby power, and this is covered by regulations in many countries, for example in the United States limiting such power under the One Watt Initiative, from 2010. In addition to a wake-up press of the power button, PCs can also respond to other wake cues, such as from keyboard, mouse, incoming telephone call on a modem , or ...

  5. AC adapter - Wikipedia

    en.wikipedia.org/wiki/AC_adapter

    An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.

  6. Consumer electronics - Wikipedia

    A 2012 study in the United Kingdom, carried out by the Energy Saving Trust, found that the devices using the most power on standby mode included televisions, satellite boxes, and other video and audio equipment. The study concluded that UK households could save up to £86 per year by switching devices off instead of using standby mode. [52]

  7. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    Where power inverter devices substitute for standard line power, a sine wave output is desirable because many electrical products are engineered to work best with a sine wave AC power source. The standard electric utility provides a sine wave, typically with minor imperfections but sometimes with significant distortion.

  8. UEFI - Wikipedia

    Furthermore, if the computer supports the "Connected Standby" feature of Windows 8 (which allows devices to have power management comparable to smartphones, with an almost instantaneous return from standby mode), then the firmware is not permitted to contain a Compatibility Support Module (CSM). As such, systems that support Connected Standby ...

  9. Wake-on-LAN - Wikipedia

    en.wikipedia.org/wiki/Wake-on-LAN

    A physical Wake-on-LAN connector (white object in foreground) featured on the IBM PCI Token-Ring Adapter 2. Wake-on-LAN (WoL or WOL) is an Ethernet or Token Ring computer networking standard that allows a computer to be turned on or awakened from sleep mode by a network message.
