The cats walked across the laptop and, I'm guessing, caught a claw under the '3' key and ripped it off!
It's pulled the small white hinge off and snapped a tiny part off it so it won't stay on any more!
It's an Alienware 17. I've tried looking on Ebay and Googling, but I can't find anything that looks the same!
Dell will only supply a whole new keyboard.
Anyone know if there's anywhere likely to have either the hinge, or key, or even to buy a scrap keyboard to pull the keys off?
