i have an IBM thinkpad and the keyboard on the top left corner is very slightly wobbly.. (its an amazing keyboard but it wobbled slightly... i took the laptop apart and found that the top left corner of the keyboard rested on some big copper cooling pipes and they where slightly too low so i packed the keyboard up with a small square piece of that alluminum tape you can get (folded about 3 times on itself)

i don't think this would make any difference but is it possible that it would somehow insulate the copper pipes and if so would it matter? the laptop is still running fairly cool (like always)  but i am worried i might lose a few degrees of cool to it

(btw this fixed the keyboard problem completly and now i have the best keyboard i have ever laid fingers on... xD

i am probably worrywarting
