Make computer go to sleep after USB phone charging is complete

I used to have my desktop Windows XP pc go to standby (S3 suspend, I think?) when it idled for over an hour or so. Now I charge my iPhone 3GS from a USB port, often right when I go to bed. Ideally I'd like to save electricity by having the computer go to standby as soon as the phone is done charging.

"Similar to @Jared's (admittedly ""cooler"" answer) you can buy a simple USB wall charger for a few dollars. They are cheap, and simple. Or, you might do like this guy's Instructable and DIY your own.

This doesn't in any way actually answer your question of how to make your PC shut down after the phone is finished charging via its USB cable, but it does seem rather superfluous to run an entire PC just to charge the phone via the 5V line on its USB hub. :)"

Check whether your computer's BIOS has an always-on USB option. This provides power while the computer is asleep, so you can put it to sleep immediately while the phone charges. Some computers have yellow USB ports for this purpose. (I'm not sure if they have them on desktops, though.)
