  2. 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 ...

  3. Power symbol - Wikipedia

    en.wikipedia.org/wiki/Power_symbol

    IEC 60417-5009, [8] the standby symbol (line partially within a broken circle), indicates a sleep mode or low power state. The switch does not fully disconnect the device from its power supply. This may appear on a toggle switch opposite a power on symbol, alone on a pushbutton that places the device into a standby state, or alone on a button ...

  5. Sleep mode - Wikipedia

    en.wikipedia.org/wiki/Sleep_mode

    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 .

  6. Uninterruptible power supply - Wikipedia

    en.wikipedia.org/wiki/Uninterruptible_power_supply

    A line-interactive UPS maintains the inverter in line and redirects the battery's DC current path from the normal charging mode to supplying current when power is lost. In a standby ("off-line") system the load is powered directly by the input power and the backup power circuitry is only invoked when the utility power fails.

  7. Power gating - Wikipedia

    en.wikipedia.org/wiki/Power_gating

    Power gating uses low-leakage PMOS transistors as header switches to shut off power supplies to parts of a design in standby or sleep mode. NMOS footer switches can also be used as sleep transistors. Inserting the sleep transistors splits the chip's power network into a permanent power network connected to the power supply and a virtual power ...

  9. Hot spare - Wikipedia

    en.wikipedia.org/wiki/Hot_spare

    The other unit is a hot-standby or a hot spare unit, ready to take over if the master unit fails. When the master unit fails, an automatic failover to the hot spare occurs within a very short time and the outputs from the hot spare, now the master unit, are delivered to the controlled devices and displays.
