I have a psp 1000 and about a month ago i received a problem with it.All the functions work on it and same with the buttons on it. But it doesnt work with any battery in it. The only way it will turn on is if it has the Ac cable plugged in. If the battery is put in with the AC cable the orange charging light comes on. But after a while it will turn off and stay off. I have already tried multiple batteries and still does the same thing. Please help!!!!!
