Bushfiva and Matt, thank you very much for your replies.

I don't think my computer has a fan. If it does, it’s a very quiet one. Am a little nervous about trying the vacuum. I might opt for the compressed air. Interesting to know that a laptop can run hotter when plugged in. Might have to try the warranty angle with my son. I can just see the eye rolling now…. And of course there will be the usual “What did you do?”

I will try your suggestions tomorrow morning when I’m feeling more awake. Thanks for your detailed rely. It all helps and occasionally a little even sinks in. Was relieved that my laptop doesn't have a "Caution, do not place directly on skin as laptop may become hot" warning. Good luck with that therapy thing.
Thanks again, guys!
(Now if I could only figure out how to do the quotes in the blue boxes—a challenge for another day.)
