Oh... good. o_O
Nice to know it's well-designed then. :-/
Seriously, I bought my sister a new laptop because hers was lame. This
new one is really failing to impress me.

Well, initially I didn't even *install* the wireless drivers. (I
couldn't, because I didn't have them to hand.) Made no difference. Ditto
for sound and video.

I don't think CPU temperature is safety critical. The CPU basically burns
out before the heat gets high enough to set anything outside the case on fire.

Well, perhaps. But CPU temperature is *utterly* critical to being able
to continue using your laptop. If it gets hot enough, the CPU will burn
out, and then your laptop is a very expensive paper weight. (!)
I'd be... kind of "upset" if that happened to me. o_O

Yep. But that's not safety critical. :-) Indeed, that's exactly why it
*isn't* safety critical. Unlike say batteries blowing up, which *are*
safety critical and which therefore have hardware in the charger to keep
from blowing them up.

Then they can sell you a new one (naturally you'll buy the same brand as
the one that melted, won't you?).

Probably some sort of continuous calibration system to account for
temperature changes etc, I guess the head movement mechanisms need to be
controlled pretty accurately!

Can this actually happen though, or does the CPU just shut down before it
knows it is going to melt?
When I built my sister's PC the heat sink clip had snapped without me
knowing, so the heat sink was hanging off one side. Every time I tried to
install Windows it just turned off after about 20 seconds. It wasn't until
I took the case off that I realised the problem.

Yeah, I always thought the sounds a HD makes when turned on was just the
drive mechanism trying to find track 0 or something like that.

Yes, I *will* buy the same CPU brand as the melted one. You know why?
The rival brand uses a different socket. :-P
OTOH, it would probably be both *cheaper* and more beneficial to just
buy an entire new laptop! ;-)

I am unsure. One would hope that powering down the system if a
hard-limit temperature is reached *is* in hardware rather than software.
OTOH, here we have a laptop which got sufficiently hot for the CPU to
malfunction fairly seriously, yet still the power remains on.
