There's this long over-due job for myself to fix my 7-year old Thinkpad laptop (I bought it on the 2nd day after I landed in this country) it's been very strong and sturdy just recently after a long while of totally being unused the keyboard seems to behave dodgy. Occasionally I got keys that are not responding, and some seem being pressed all the time so I saw my cursor moving around like crazy. Not quite usable. I decided to get a new one and placed an order on Ebay (btw Ebay sells everything). And I just left the detached keyboard in the sun for the afternoon. Amazingly when I put it back it seems to be back to normal.
