
S3 (G1-S3): Commonly referred to as Standby, Sleep, or Suspend-to-RAM. RAM
remains powered.

S4 (G1-S4): Hibernation or Suspend-to-Disk. All content of main memory is saved to
non-volatile memory, such as a hard drive, and is powered down.

S5 (G2): Soft Off. Almost the same as G3 Mechanical Off, except that the power supply
still provides power, at a minimum, to the power button to allow return to S0. A full
reboot is required. No previous content is retained. Other components may remain
powered so the computer can "wake" on input from the keyboard, clock, modem, or
LAN.

G3: Mechanical off (ATX supply switch turned off).

LEDs

mSATA Activity LED

Connector J12 includes an output signal for an mSATA activity LED that corresponds to the top
LED at position D1 on the VL-CBR-5016 paddleboard. Refer to the section titled
"Indicators/LEDs" on page 39 for more information.

Power LED

The power LED (the bottom LED at position D1) on the VL-CBR-5016 indicates that the
paddleboard is being powered by the +5V supply (though it does not indicate that all S0 power
supplies are good). The LED is lit only when the board is in the S0 power state. If the board
enters a Sleep or Hibernate mode, the LED will not light. Refer to the section titled
"Indicators/LEDs" on page 39 for more information.
