Why are number keys 1-9 not working?
I just replaced the uppercase on my Macbook Pro with a unibody piece from iFixit. On installation, everything went smoothly and the computer booted normally. However, when prompted to enter my password, I realized that certain numbers were not working. I used a wireless keyboard to gain access, and then proceeded to test EVERY key on the keyboard only to conclude that the number keys 1-9 and their subsequent SHIFT+ commands are not working, while all of the other keys remain fine. Any suggestions as to what to do? Is it a system problem or a hardware problem? The Upper Body is brand new from iFixit, just got it in the mail today.
Review the part numbers you might have gotten the wrong keyboard. Also compare your old keyboard with the new one do the keys have the same function key layout and the keys look the same and same placement. You might also have a system for a different region (non-US).
