    I haven't noticed what comes on, but mine randomly turns on also when plugged in to the computer for USB charging only.

    Something similar came up about a week ago I remembered.

    Are you using the stock cable that comes with the phone? Some people have reported problems with alternate/cheap cables/adapters.

    Are you plugged into a USB port on the back of the computer? Sometimes the ones on the front of a computer are not configured as well or in the same way that the ones on the back are.

    Maybe the front USB port is outputting less current that is similar to what you would get from a car charger. Or maybe it is USB 1.0 or something.

    Fix:
    App Tray -> Car Panel -> Menu Key -> Settings -> Turn off Auto-Launch

    I recall reading that the car dock itself involves a usb connection with some pins shorted or something to that effect - the Evo senses that to go into the car dock mode.

    Might try changing that cable out or verifying your usb drivers are ok by downloading HTC Sync if you're on a Win PC.

    Mine kinda wakes up when charging, I never bothered to see why - maybe it gets new email or syncing or something I'm not paying attention to.

    That red title sure looks snazzy with your name next to it now ;)

    Yeah, from searching around a bit more, it appears a USB cable/connector with pin 4 grounded will cause the phone to go into the Car Dock mode.

    I don't have the car dock issue when charging via PC, but my screen DOES come on at random times, and when it does, I notice the battery bar doesn't have the charging icon. I believe that's probably a feature to prevent overcharging or whatever. After that the screen would come back on randomly and start charging again, showing the charging icon in the battery meter.
