I just received my 14"inch Thinkpad Edge. After typing on it for a few minutes, I immediately noticed that the backspace key isn't as responsive as the other keys. I have to hit the backspace key a lot harder than the other keys. I really like the laptop and I know this is not a huge deal, but I also know that this is going to really annoy me down the road. Just wondering if anyone has had this problem? Any suggestions would be greatly appreciated.
