I have a CFW'ed PSP that previously ran perfectly, but after not using it for around a month I decided to pop it out of it's case, give it a charge (AC adapter) and then play on Kingdom Hearts. The yellow light come on when I charged it, and once it had charged I disconnected it from the charger and then went out. When I came back in, and tried turning the machine on, nothing happened. No lights come on, not even when I try charging it. Any ideas what I can do to try and fix it? I'm willing to reward those who help me solve this problem. Thanks in advance, WiLDFiRE.
