I have my desktop PC at home set up to accept remote connections, and I often connect to it from work on my laptop via mstsc.exe. However, every time I remote to it, I find when I go home that despite the monitor being on - it's not receiving an image and it looks as though the computer is hibernating/asleep. I basically have to restart it whenever I get home and I know there's an answer for why its doing this.

More details:

• When exiting the remote session, I have tried both logging off the account, and closing the RDP window without logging off; both give the same result.
• When I get home to the desktop I of course try moving the mouse, ctrl+alt+del to see if its responsive to restart, multiple key-press to see if I can get any audio out of it; It seems pretty obvious its sleeping/hibernating in some way: Nothing happens in any of these cases and a physical restart is necessary.
• Both desktop and laptop are running Windows 7 Ultimate.

I'm thinking it really is sleeping/hibernating it, and I'm not sure why because left alone my desktop's power options are set to never turn off the HDD or change its state - I leave it on 24/7.

This could be a stupid error on my part but I just can't see it! Thanks.
