Changing the A/C input unit on the psp (the yellow slot for power) and month later after no mishaps, the psp begins to randomly power down (suspend/what'd happed when the power switch is flicked). To start up again, the battery must be removed and placed back in again (there's no cover, so batt's wedged in with a bit of folded paper) and even then it doesn't start up all the time. Opened it to check, everything is as it should be.
It charges fine and since that's all it's meant to do, should that happen?
It's 1am here so I'm jus gon use

That yellow thing is the component I replaced. And the problem didn't begin immediately after.
