this should be safe, but use at your own risk.

ok tried 2 change settings but the psp says that the ac adaptor is not connected when it is any help please???

Uuuuh is your adapter connected to the psp? If it's not connect it and giver sh*t.

managed 2 get it sorted need 2 try and get my f*****g card sorted now

hey he said its connected to the psp... i think you better check if the other end's connected to a nuclear reactor

But seriously i think you may have a hardware problem. But before jumping to conclusions just try upgrading to 2.0 and then check... if everything's hunky dory then downgrade to 1.5. If the power problem re appears again in 1.5 then i think you are stuck with a nice piece of useless hardware

So were you able to downgrade successfully - do you need any help with the homebrew on 1.5? Let me know!
