I just went to turn on my PSP and nothing happened... I was horrifed at first and thought that somehow it was bricked while I wasn't using it. I tried plugging in my USB power cable and the orange light didn't come on. So I took out the battery and tried to plug in the cable and the orange light did not come on. I took the battery and put it back in and turned it on and it came on. The battery said it had 0.01% charge and the green light quickly started to flash. I don't know how my battery could have gotten so low because I have it set to go to sleep after like 5 min. Anyone ever had anythin similar happen? Also does anyone anyone know if you plug in an AC adaptor to the PSP will it turn on with no battery in?
