This matches Windows behaviour at least as of Windows 7.
Signed-off-by: Zebediah Figura zfigura@codeweavers.com --- Windows does not seem to do it using SystemParametersInfo(), nor using SetThreadExecutionState(). I suspect it is instead using the Power*Request() APIs, but as far as I'm aware implementing those would require getting at an external library such as X11 or dbus from ntdll (or kernel32), which is not permitted.
