I once came home to a powered-down Windows machine that had been doing a
render. When I turned it on, I got a pop-up from Windows saying it had been
shut down due to temperature problems. (Poorly-ventilated machine inside a
cabinet.)
I suspect both the OS and MB monitor the heat.

You'd buy that CPU from Acer?

That's what I ment, they can sell you a new laptop. And if eg. Acer was
fine in other ways but it, hmm, kind of.. melted, you're granted to buy
new Acer. Right?
I just might think about another laptop-brand. I might check Dell or
Lenovo, if my HP melted oslt.

I guess he hasn't. But damn, not only you beat me asking that, but you
also made me think if I should heat one up. Get some nice 70-80C to air
and vaporaze some liters of water to it...
Hmm, naah. It's too warm outside to get best out of it :(.

And they should. The OS can do pretty sophisticated things in such
manner, while estimating the overheat - it can shut down or freeze
processes nicely, it can hibernate or power down nicely etc. The MB...
Well, via ACPI it can tell the OS to do (at least most of) these things
also, but it (also) should be able to cruely cut the power, in case of
OS crashing hard (you know, kernel panic, BSOD etc) and not being able
to do anything nicely.

I am constantly baffled at people who think that buying things from Dell
is a valid thing to do... ;-)

We do run them at work, you know. For which brand do you have such an

Yeh I imagine on a lot of systems that are operating right on the limit of
what's possible there are cool things like this that have to be done.
On a side note, isn't that a pretty bad security design, in that your
handset could (in theory) be able to display a list of all phone numbers
called in your cell? I mean your phone could just store the last few
seconds worth of called-numbers in your cell, and then when you hear your
target's phone ring, trial and error through the short-list for to get their
number.
