I have a droid charge and i would like it to stop sleeping while charging in the car. I have the home dock for the phone. I have a place in my car to store the phone. I do not want to buy the car adapter. I am not spending another $40.00 for a 679K resistor so that it can go into car mode. I have in car navigation already. Is there a profile to keep the phone from sleeping while charging? Thanks for your time. Donald.
