Dave et al,
This is an ongoing issue. TC108 worked to update the accessible
temperature requirements in 62368-1 in the early 2000s based upon reports in
the popular news of similar incidents. I reviewed this in a PSES 2004
presentation which was later converted to an article in the PSE News,
15v11No2. The technical basis for reasonable requirements were drawn from
earlier work done as discussed in the paper. You can find this paper by
searching for it by name online: ‘Ouch Hot Laptop’.
Enjoy the reading upon your new laptop (which, as stated, an
attempt was made to rename these as notebooks to steer away from similar claims
– but the popular name returns).
:>) br, Pete

That’s in the plan. This one slows down apparently when it’s not too busy. If
it’s just the OS running with no programs it’s cool as can be. But if I wanted
a laptop to only do one thing at a time I’d use MS-DOS. With several programs
running and multiple browsers with multiple windows it runs the CPU full out
regardless of temp.

Get a new laptop. Intel devices now slow down if they get too hot. My new
laptop barely gets warm.

I’d like to ask the same question of my “name brand” laptop with the same
circumstances. The CPU runs just under 100 degrees F according to Intel
diagnostics and the case bottom runs hot enough it can’t actually sit on a lap.
