Default WinXP laptop temp question

I may try that next, but I'm not expecting much. Coincentally or not, this
is the same laptop that I lost the double USB port in a few days ago (which
is located in the same area as the hot spot), and was never able to
resurrect (via any device manager uninstalls and reinstalls, etc). That
double USB port was apparently damaged at the hardware level, which I still
find hard to believe.

The obvious question: was the hotspot in evidence before the USB port
failed? If so, it seems not inconceivable that it could be related: the
heat fried a chip, or (though I think this would require _great_ heat)
desoldered something. Or could have just been the final factor that
would separate a minuscule crack that had developed, or something.

Can you get a thermometer into the port? (Maybe a meat/oven one? Though
don't short anything.)

I don't know whether it was hot before, or that could have answered it. :-)
I don't have such a thermometer, but I can tell you this much: if you leave
your finger inside that metal port for about 5-10 seconds, you will need to
pull it out. :-) Paul seemed to be suggesting that might be around 65C.
I just looked this up on the Internet, and according to one article, it says
60C (for up to 5 seconds). I'm not sure if anything inside the laptop is
supposed to run that hot, but maybe it could (it does have a NVIDIA graphics
chip, afterall). Oh, and I did check it out with the battery removed, but
got the same result.

Do you need a thermometer though, if the owner knows how hot
it ran new, and it's running a lot hotter now ?

If some circuitry in the same area melted, you'd want to
have a look inside, to see if the thing could be saved.

There are sites that have take-apart guides for a few laptops.
You can't always find the exact model you want though.

I don't know if it's running a lot hotter now, so that's an unknown. As for
tearing it apart, I'm not sure it's going to do much, as I figure if there
were hardware damage, it's more likely to be internal (at the IC level).
But thanks for that reference, which looks good!

Bill, I've repaired a number of Dell laptops and one thing I've found is
that if the USB port is on the right rear corner and the port feels loose
it's most likely the solder connection that hold the port connector to the
daughter board has broken loose. The reason it's feeling hot is probably
because that port connector is also the heat sink for the nearby power
regulator for the daughter board the USB port is installed on.

Look up the model number and see if you can find a visual that shows a photo
of the board. The big tell is that the port connector itself will feel
loose compared to the others and if it's located on a daughter board in the
right rear corner then that is probably the reason.

Just a guess.

Thanks for the suggestion, but it feels pretty tight, like the other
connectors.

Since I bought this on eBay for about $100, I might just wait and see if I
can find another one that isn't too expensive to simply replace it. Either
that, or just live with my other laptop experiment, which is a Dell Latitude
E6500, which seems to be a much nicer and more elegant laptop, anyways. :-)

That obviously eliminates a faulty battery as the source of the heat,
and probably also the charging circuit. Running it _on_ the battery for
a while would eliminate a poor connection at the power socket (if it
still gets warm), but usually you'd know about that as those get _very_
hot, and you'd usually smell hot plastic, and (assuming you have the
usual power settings) the screen brightness may vary. (If you sniff
around the hot port, _do_ you smell anything amiss?)

No, nothing amiss. And again I don't know if this was related to the other
problem, either, but since I've got another laptop to mess around with, will
probably just let it go.
