Windows 7: Power Options / Netbook / Sleep Mode

I want to enable my Windows 7 netbook to automatically wake itself from Sleep Mode when it's plugged in.

If you want more detail...

I want this because I basically am using the netbook as a jukebox for my car--and it will always be plugged into the cigarette adapter, but I have it wired to my trunk because I will control iTunes remotely, but I can't power it up remotely, so I just want it to wake from sleep automatically when I start the ignition. Thanks!

Just a suggestion, but I think using PC's in cars like this is in the past! Grab a USB MP3 player like everyone else. I got one in my '95 Ranger and it's limited only by the size of my USB stick or external HD.
