Things You'll Need
Instructions
Power off your PSP, slide the battery cover off of the rear of the unit and remove the battery.
Locate the seam on the sides of the battery. This is where the two halves of the casing connect.
Insert your knife in the seam and run it along the sides until the two halves separate. Place the empty half aside and you will be left with the half of the case with the circuit board inside.
Lift the board and turn it over as if it were a page in a book. It will now be to the side of the battery case.
Locate the black chip with metal pins sticking out of it. Next to one of the pins will be the number "19."
Cut the pin just below the "1" in the "19."
Place the circuit board back in the case.
Line the edges of the two halves with hobby glue and fit the two halves together. Wait for the glue to dry before putting the battery back in the PSP.
