I have an HP Touchsmart running Microsoft Windows 7 Home Premium 64-bit Edition. This computer is supposed to be in a lobby running a slide show. I don't want it to run 24/7 but would like it to shut down/hibernate from 5:30pm to 7:30am, and when it comes back online it should run the slide show. Turning off and restarting manually is difficult due to its location. Any suggestions on how to do this?
