I got this laptop from a friend who dropped it and cracked the screen. I removed the entire top of the computer and hooked it up to an LCD monitor that I have. Everything seems to be OK with the computer, I even upgraded from Vista to Windows 7. The only issues I was having was my thumb hitting the touch pad while hitting space bar and the num lock key not turning on the keypad. I downloaded the synaptics pointing device thing and disabled the touch pad so that problem is fixed but I can't find any information on the numerical keypad not working. I do a lot of stuff that involves numbers and it is getting really annoying to have to use the top row of numbers. Any help will be appreciated.
