[ubuntu-uk] Strange high CPU usage problem

That is very similar to my problem: both Flash and Java apps caused exponential CPU usage. Shutting down everything would cause the machine to settle down but it wouldn't become stable until a full reboot. I would suggest checking to see if there's a BIOS update for the machine as I've just done that and it's seemed to resolve the heating issues that I had that apparently came from the Nvidia GPU. Also you don't mention the version and architecture of Ubuntu that you're using which might be useful to know. 

Sorry, I am running Ubuntu 10.04. Dell does have a new bios update for download (http://dell.to/ez3bkC), which I can try. However I thought I'd double check here before running it .. :) 

>From the instructions: 
. If not already logged in as root, change user ID to root. 
2. At the shell, switch to run level 1 by executing "init 1". 
3. Make the update program executable by executing "chmod u+x update_program_name". 
4. Run the update ... 
... 

Is this a common way of updating the bios on Ubuntu? Running "sudo init 1" from a gnome-terminal didn't quite work for me. I got a screen with text that eventually stopped running. Thankfully pressing the power button briefly responded by shutting down. Should I be doing all this without running X? 

Thanks, 
Rossen
