Gateway laptop keyboard alphabet values?

Since I have hi -speed internet, my Laptop Keyboard has changed to a numerical keypad on the right side of Gateway Laptop Keyboard . I went into troubleshooting on the control panel, but nothing was corrected. I have Windows XP. and i want to buy a HP Laptop Keyboard.

Could an electrical storm have caused this? I have turned off the computor, but this did nothing either. Also, my mouse doesn't work anymore, even after installing new batteries.

Thanks
