Things You'll Need
Instructions
Turn your PSP over so you are looking at the chrome circle with the inset "PSP" logo on the machine's rear face.
Push down on the release button for the battery door, located on the far left side of the console. Lift the battery door up and away from the body of the PSP.
Place your palm over the battery and turn the PSP screen-side up to tip the battery into your hand.
Twist the paperclip into a tight "U" shape and place one end on the battery's "+" terminal and the other on the "-" terminal. Hold it for several seconds.
Replace the battery into the compartment and fit the door back into place to complete resetting the battery's memory. Connect the PSP to a power outlet; if it does not turn on immediately, give the battery six hours to completely recharge.
