Hibernating your desktop on a time schedule.

The Shutdown.exe command will not let you set a time-out period for hibernating.
ie. this does not work shutdown.exe /h /t 7200

Yes, you can download programs to do that.  On a corporate laptop, we are locked down from running external programs.

A elegant solution I found was this:
timeout /t 7200 /NOBREAK > NUL && shutdown /h

It uses the native Windows timeout command to do the waiting.
