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.
