All you need to take it apart is a small philips screw driver. Start with the screw on the face plate then the other four (two on the right and two under the battery). DO NOT UNSCREW THE SILVER SCREWS AS THEY HOLD THE MOBO AND WIRELESS MOBO IN PLACE. After youve done that lift the faceplate FROM THE BOTTOM UP and your psps screen as well as other stuff should be exposed so you should be able to see the power switch should look like a small metal rectangular box with a black piece of place going into the outside switch. If you dont then it might be on the underside of the board, i cant remember too well cuz its been awhile since ive taken my psp apart. Anyways look at and see if anything looks like it needs soldering if so then thats as far as i can take you lol. Well if you need a new power switch then check out divineo.com they sell the entire board that the power switch is connected to and the new board literally just SNAPS into place on the psps main board; well by a ribbon cable actually lol
