My psp doesn’t seem to accept a charge from my (offbrand) battery, which will be replaced. But if I take out the battery and try to charge and play which I used to be able to do, it won’t turn on. Recently my (offbrand) charger was accidentally kneeled on by my brother, causing it to unplug. It still worked for 2-3 days, until now. I have tried usb charging which is turned on but it won’t work. I would love to know what is wrong with my system as I would hate to let $90 go to waste (b-day present purchased two weeks ago). Thanks in advance!
