I usually hibernate my Windows-7 Desktop PC during the night. Is there any way to tell Windows it should switch off the PC absolutely and utterly and completely, such that the only thing that can ever resume the PC is the power button? As it is, the keyboard lights are still on, and sometimes the PC is hanging in Bios password entry in the morning. 

I know I can change which devices can wake up the PC [by using powercfg](https://superuser.com/questions/215558/how-do-i-determine-the-cause-of-resuming-from-hibernation-in-windows-7), but this is something I need to do again and again when I plug in the keyboard or the mouse into another USB port. Even is everything is switched off there, the keyboard lights are still on and the PC consumes unneccesary energy. Of course, I can also wait until the hibernation is complete and crawl under my desk every day to physically cut power, but I'd prefer Windows to behave decently. 8-/

CLARIFICATION: I do not want to shutdown but to hibernate since I do not want to wait for a couple of applications to start in the morning. Still, after writing the RAM content to disk, the PC has no business consuming any energy, anymore, or much less start itself without my consent.
