hibernate and stand by

[Steve Teeples]

Does someone have an example of C# code (VS 2005) that puts a system into
hibernation or stand by and then after some period of time wakes up the
system?

I need to write a test that does this functionality.

As far as I know, there is no way to enter standby/hibernate state from user
code, that is without user intervention. You can awake a system by using a
timer (System.Timers. Timer or Threading.Timer ), a system in standby or
hibernate state will wake up at the next timer event.

Re: hibernate and stand by

Is there a power management class in .NET 2.0?

Re: hibernate and stand by

No, but there is a Win32 API to set this state, provided your system is ACPI
compliant and the BIOS is set-up to enable S4 and/or S3.

Here is the declaration (not tested!)....

[DllImport("Powr Prof")]
extern static bool SetSuspendState ( bool hibernate, bool force , bool
disablewakeup );

usage:

SetSuspendState (true, true, false); // force hibernate, disable all wakeup
events
SetSuspendState (false, true, true); // force suspend and enable wake events.
SetSuspendState (false, false, true); // broadcast PBT_APMQUERYSUS PEND event
and suspend if all agree.

If you are using .NET 2.0 you can just call Application.Set SuspendState.

Check out the documentation at:
