*Dell Inspiron 9200 Laptop, Ubuntu 9.10 x32*
Pent M 1.8Ghz - 17" widescreen display - 1gb 333mhz ram - 60 gb hard drive -
Intel or Dell wireless adapters b and/or g, and/or a (Intel Pro 2200 wifi
b/g adapter)
I have tested the laptop many times...I have had windows XP on it for awhile
and had up to 7 browsers and some with flash running and have never
encountered the crazy fan problem. It only happens to me in Ubuntu and
Intel Speed Step is turned on.
Just the other day the computer went through an update inside of ubuntu and
the whole time it was updating + about 4 hours that I was at work the fan
was going nutz. The laptop was out in the open on a wooden table so airflow
was good. I have taken the laptop apart and made sure no dust is blocking
the vents and all the heatsinks are clean.
I haven't heard of that powertop thing...think I might give that a
try...thanks for the suggestion!
