Calling all Linux gurus, Google ninjas, and Dell Linux users..

So, I'm a huge fan of open-source software. Changing to Windows isn't a solution for me.

But, I currently use a Dell 15R (N5010). Previously on Ubuntu's website, it was listed as one of the most Linux friendly laptop's (around a year ago, when I first purchased it)..

When I ran Window's 7 (64 bit) on this computer, I had no overheating problems.

When I ran Linux 9 (Linux Mint 9, 64 bit, specifically) - I had no overheating problems.

But since 11.0 and up, I've had heating problems. From what I've read, it seems to me that this may be a kernel issue..?

Now I have Linux 12.04, Ubuntu, respectively. When I boot from a CD, there's no heating problems..but after I install the system.. I idle at around 60 - 90 celsius..sometimes higher. And sometimes, it gets so hot and my computer simply shuts down. That's just when I have Firefox open, doing nothing but minor web browsing. One tab open with something like Twitter, or Google on that tab..

I've used lm-sensors, powertop, Jupiter and tweaked the power settings out as much as possible, but the lowest temperature I can reach is about 55 celsius.

My computer feels very hot, as if the fan isn't running very strong at all. I can't feel air pushing out of it as I do when I have Windows loaded onto it.

Can anyone help me solve this problem? I need my laptop to stay cool because I do quite a bit of media/music production. When I did media production on Linux Mint 9, it never got this hot. I've cleaned my laptop's guts. No dust, loose parts, etc. Also, there are no settings in the BIOS to set fan control, as some other laptops have.

If you need/want more info that could be helpful, please let me know and I'll post it.

Edit: The good news is that I'm under a warranty. If there's no way to fix this.. can someone suggest a super Linux friendly laptop? Preferably i5 or i7.

I've also posted this on reddit, too.

This worked for me on Dell inspiron 3521 - Ubuntu 13.04 . Less sound of fan webupd8.org/2011/06/linux-kernel-power-issue-fix.html (Using tlp as well - webupd8.org/2013/04/improve-power-usage-battery-life-in.html) –  mac Jun 23 '13 at 10:12

I'm using a 17R myself, and it's working pretty well. I have read that there was a kernel issue with power management, and presumably temperature, but that it was fixed in version 3.2. If you run "uname -r", you can see your current version of the Linux kernel. You should try updating all the packages on your installation to get the latest version. Try running the above command using both the live cd and the actual installation to see how they differ.
