Answer to "Where is the left palm rest temp sensor?"Hi there, I know this is an old topic, but i’ve got exactly the same problem. When there’s no pressure applied to the housing everything works fine, but with pressure (like your lap or just a table) the fan spins up raptly and the cpu is getting hammered. I can’t find any place where something would separate the connection. And I also don’t have a item that was sitting there. Could it just be the top part of the trackpad ribbon? And if so would a replacement cable solve the issue?
