Hi, I've had some overheating problems with my laptop, which is apparently common with this model. Since its few years old, I figured it's out of warranty so I removed the keyboard and opened the computer up to clean out the area around the fan, which was very dirty. The heating problems are better but now several of my keys on the left side of the keyboard don't work (1,a,Z,q,tab,caps lock, esc). After cleaning out the area around the keyboard again, it was fixed but the problem came back after a few days. Any suggestions? Is this a keyboard problem or something more serious? Thanks for your help.
