S5 Eco Mode

Kontron’s new high-efficient power-off state S5 Eco enables lowest power-consumption in soft-off state – less than 1 mA
compared to the regular S5 state this means a reduction by at least factor 200!

In the “normal” S5 mode the board is supplied by 5V_Stb and needs usually up to 300mA just to stay off. This mode allows
to be switched on by power button, RTC event and WakeOnLan, even when it is not necessary. The new S5 Eco mode
reduces the current tremendously.

The S5 Eco Mode can be enabled in BIOS Setup, when the BIOS supports this feature.

Following prerequesites and consequences occur when S5 Eco Mode is enabled

» The power button must be pressed at least for 200ms to switch on.

» Wake via Powerbutton only.

» “Power On After Power Fail”/“State after G3”: only “stay off” is possible
