Hi there, I just bought my psp yesterday. My battery info shows that charge level is 0% and shows battery power left -.Orange light is on for like 5 minutes when i plugged in the current and turn to green after that showing battery status charge complete . If I play it from the AC adapter everything works fine, but as soon as I take the adapter out the psp doesn't want to play/ turn on and shows that my battery is low and needed to be charged. What is the problem? Thanks a bunch!

most probably battery problem.
did you buy a second hand unit?

first hand. brand new.

try taking it back to the shop and ask them to test it on site.
charging should be OK if it is new..maybe an old battery?
