Which ACPI state turns the CPU and RAM off and copies the contents of RAM to a temporary file on the hard disk?

  • S0
  • S1
  • S2

    Explanation:

    The Advanced Configuration and Power Interface (ACPI) standard provides support for power states that are very important to mobile devices such as laptops.

    S0 – The computer is on and CPU running.
    S1 – CPU and RAM have power, but unused devices are powered down.
    S2 – CPU is off; RAM is refreshed.
    S3 – CPU is off; RAM is set to a slow refresh rate.
    S4 – CPU and RAM are off (and RAM contents saved to a temp file).
    S5 – The computer is off.
