I recently bought a replacement keyboard on ebay for my MBP and just installed. It's been about a week and only today I noticed the caps lock key does not work .. I do not know if it was this way, or if it just stopped recently. I was curious if this was a problem common? If not, is their anything I can do as a substitute for caps-lock? Another key maybe? Or a button on the taskbar or something? I can not really do anything. I do not know if it was damaged when I bought it, or if I damaged during installation, or if I just installed something that has stopped working suddenly. I don't know why capslock key won't work. Please help me.
