my 3 year old got hold on my laptop and now some functions on the keyboard like the arrows, page up, page down, home, and end, do not work right. also the number pad is built into the letters so that you have to push Fn to make them work, well somehow that is now reversed o that i must hold down the Fn key to use the letters. I am running windows xp.

It is not a name brand i had it built by a computer shop in my old hometown, the stickers under the battery are, RE7752201633 1FL91 05 next CFL91965G1, Stickers on the bottom are 10-7019-05020, another in a diamond 2002/95/EC , Another showing battery ratings has model: FL91
