RE: Power off a BSP

Tech-Archive recommends: Fix windows errors by optimizing your registry

What you need is suspend, not power off.
The system can not wake up from power off, but can from suspend.
You can use API "SetSystemPowerState(NULL, POWER_STATE_SUSPEND,
POWER_FORCE);" to suspend the system.

Hi,
I'm working on a Kiosk-like device. The main application shall bring
the entire device in Stand-By (low power consumption). The device
shall wake up every hour, check the battery state and go back to Stand-
By or turn the power off completely.

How (where) can I turn the power off in a BSP?
It is safe to turn off device power supply in OEMPowerOff (according
to MSDN it isn't)?

Thanks.
