change celeron M cpu in laptop to "slower" model

[Kasper]

Hi, I have an acer travelmate 242 LCE with a celeron m 2.4 mhz. I have
googled around, and it seems that i can change the cpu, within the
celeron-range... Is it that simple? Is it just exchanging the cpu
(socket 479), or do i need an other BIOS, or something? the laptop has
always been very noisy (fan) and i was wondering if changing the cpu
to the slowest model - celeron 350 - would improve on that problem? -
as it probably uses less power... i dont use it for very demanding
tasks, and i have tried to clean the laptop, even re-applied thermal-
paste, but the thing still runs the fan constantly.
I have recently experienced the BSOD on several occasions, so i was
thinking of trying to change the cpu anyway. (the HDD runs in an other
laptop without problems).
Look forward to hear from anybody with an opinion....

Is the original processor listed here ?

Maybe you should have got the problem fixed under
warranty, when you first noticed the fan problem.

Acer may not be too happy, to see any user modifications
or improvements. With laptops, a warranty is a valuable
thing, since a laptop can be so expensive to fix yourself.
Getting the unit repaired under warranty, is a lot
better than turning your laptop into a giant experiment.

If you are experiencing BSODs, you should be keeping careful
notes of where the thing is crashing. The name of the driver,
and whether the crash is in the same driver all the time,
or the crashing is random in nature. That may help identify
what subsystem is at fault.

If there are any utilities that can monitor temperatures, you
may want to check them and see if any temperatures are listed
as being extra high. Perhaps when you took the unit apart,
you did not reassemble the thermal components properly. There
are probably heat pipes in there, connected to the CPU and
GPU, and if they are not reattached properly, something could
now be overheating.

Maybe this is the original processor, a Mobile Intel Celeron Processor
at 2.40 GHz in a 478 package. The power dissipation is 35W.

http://processorfinder.intel.com/details.aspx?sSpec=SL75J

If you look at other Mobile Intel Celeron processors in that
family, the other ones don't save a lot of power. There are
some at 30W for example. I'd probably try to stay with the
same family code, in the hope that the BIOS would accept it.
(The 1.7GHz SL6VG is still drawing 30W, so little power is
saved.)

Note - there are many different generations of processors mixed
up in this Intel list. Your options are near the top of the
list. The ones further down the list, are older technologies,
that won't work. Some of those older ones are from the PIII
generation.

And I don't think a Mobile Intel Celeron is the
same thing as a Celeron-M. The Celeron-M is a more
modern processor, with perhaps a S479 pinout. They
are not the same animal.

Oops... i finally got the thing running with an old HDD - and a
program "cpuchk" tells me that in fact its a celeron, no M or Mobile.
Do i have a desktop-cpu in my laptop? the cpu-id-name string is"intel
celeron cpu 2.40 GHz" the cpu-id-signature is 0F29. And is there any
way of switching that with a less power-consuming CPU?
