Hi, I have a brand new Powerbook 12" and the manual says I need a phillips 00 screwdriver. So I went to Sears and bought this: (I hope the link works, but if not it is item #00941526000) http://www.sears.com/sr/javasr/product.do?BV_UseBVCookie=Yes&vertical=TOOL&pid=00941526000 But when I tried to turn the screws it didn't work, it seems at though the pointy part of the screwdriver is too pointy, and it doesn't "catch" on the screws. Help please! THANKS!!
