I have a Dell Inspiron 8200, from March 2002. Since end of
December 2004 I've started having system lockups which at first
I couldn't identify, although they seemed to be overheating
related. So I started monitoring the temperatures on all the
components in my system (I can monitor CPU, GPU and HD temp;
more on this later), and noticed that the lockups happen when
the HD temp gets around 40 C. Indeed, they are 99% of the time
preceded by a loud "click" coming from the HD wereabouts ...
haven't lost any data yet but I've started backing up
everything and getting ready to get a replacement HD.

Concerning sensors, though: under Windows I can use the
i8kfangui applet to monitor all the sensors provided in the
computer, but under Linux I only seem able to get the CPU
temperature, using the i8k module, and no other sensor module
seems to be loadable. Does anybody know how to access the other
sensors on the Dell Inspiron? Or should I suggest Massimo to
upgrade the i8k module to add the new sensors (i8kfangui has a
GPL source code so it shouldn't be a problem) and possibly
interface it all with the Linux sensors framework?

You might want to try this;

Remove the keyboard, remove the cover beneath. Take a can of air dust
(or equivalent) and *carefully* blow out the inside of the laptop.

-then-

Look at the back side and the right side of the laptop. You'll see the
intake for air and the A/C unit. Take that air dust and blow in such
that the plastic fan whirls away. Take a snapshot of the dust bunnies
and send them to Dell.


I have a 5150 Inspiron. In less than 1 year this thing started powering
off (hard) on its own, no matter the OS installed (multi-boot). I dug
around the 'net and found similar issues, all relating to OVERHEATING.
Poorly designed was the culprit, but Dell has not yet admitted to this
(but look at the Dell Linux forum or just Dell laptop forum and see
Dell's techs replies) - think of the numbers sold and it makes sense.

Anyways, aside from that, I had a dust bunny the size of a U.S. quarter
fly out. Since then I make certain to rest it on a flat surface (I cut
some steel and carry it with me) and every couple of months take it
apart as described and blow out the dust.
