It takes AAA (LR03) alkaline batteries. Have you put fresh batteries in?

okay this is what you gotta do unscrew the back of your PDA and you will see your two batteries and some stickers, in between the batteries there is a rectangle. take your screw driver and push the little bars inside the rectangle back. this will unlock your screen. if it still doesn't work hold the on button and press reset this will delete everything but also turn it on. if it still doesn't work throw PDA at wall, save up money, and get an IPad.

FROM MY YO-610 USER MANUAL--IF THE UNIT DOES NOT TURN "ON" AFTER REPLACING THE BATTERY (MEMORY) CAREFULLY REPEAT THE BATTERY REPLACEMENT PROCEDURE.
