Hi Ben (et al.)

You are right. I did a simple test which I didn't expect to work

I turned the unit upside down to see if the fan EVER went on. It doesn't.
But the effect of circulating the heat upwards and away from the processor
self-vents the processor somehow and the unit doesn't shut down any more.
Turning it right side up again causes the shut down within a few minutes. I
wonder what is causing the fan not to work? Don't suppose there is any way
of testing whether it is the fan itself or something controlling it?

Anyway I tried to take it apart and didn't have much success. The keyboard
and back panel comes off and the fan unscrews and comes loose and then gets
stuck at the left in the casing. Taking out all the screws to the underside
and the two at the back don't SEEM to let the top cover of the unit come off
to get the fan out, At any rate the back of the fan itself seems to be
connected to a heat exchanger and I cant imagine I should be able to get the
fan out without disconnecting this? And I don't seem to be able to get to
the blades to see if they are stuck or can be loosened

Does any of this sound insuperable? I am beginning to lean towards finding
a cheap working (complete) chassis on ebay which I did for a Gateway I have.
(This had the effect of upgrading my processor at the same time even if my
old 750 MHz system had Windows 2000 on it whereas the newer one is 850MHz
but has Me!) I wonder if all 5000 series chassis are interchangeable?

Apparently you'll need to remove the fan to see if it turns freely, turns with
difficulty, or just simply does not turn. To remove and/or replace the fan, I
am pretty certain that the entire top plastic piece needs to be removed first.
At least, that's the way it is with many other laptops I have torn down.
Removing the top plastic from a laptop requires time, patience and steady hands,
so one does not break it. There are usually parts that fit tightly together,
with little protrusions and notches.

You might try the following web site to download a service manual either for
your model or close enough:

http://motls.blogspot.com/2007/02/fi...t-packard.html

To control the fan, you might poke around the internet for a fan control
utility. Somebody did a nice one for several Dell models, but it does not seem
to work with other brands of laptop computers.

That is pretty much what I was expecting but there is a manual for a generic
HP at physics.harvard.edu which suggests that the whole unit has to be
stripped pretty much down to the mobo to get the fan out. I was hoping to
be able to poke around in the fan a bit but cant get it off the chassis to
do this.

I wonder how much of the instructions are actually necessary with this model
to do some poking around?

how about if you just run it on one of those cooling pads that run the
fan off the usb port? I bought one at staples.

One other fairly easy thing you can try is to get a can of compressed air, point
the nozzle inside the vent where air enters or exits the system and blast away.
If you hear a whining noise, the fan is spinning freely. If not, you got
trouble on your hands, and some disassembly is required to repair.

No way can I advocate running any modern computer if its cooling fan has failed.

HP (like Toshiba) is generally pretty poor about making service information for
its notebooks available to the general public. physics.harvard.edu and some
other web sites do all of us a favor by posting some service information and
even whole service manuals on the net. Still, disassembly, repair and
reassembly is a tedious job involving flimsy plastic, thin cables, and tiny
screws. Do it carefully and take your time... Ben Myers

What exact model Pavillion is it? I may have the service manual for
it.
