I have a serious overheating problem. I installed Ubuntu 14.10 2-3 days back and it is experiencing high overheat problems. I am using a Dell XPS L502X PC with Nvidia graphics. I know that I should use an optimizer like nvidia prime and bumblebee but the problem is that my PC wont stay on for more than 6-7 minutes after which it auto shuts down due to overheating and the machine is at a burning temperature.

I cannot download bumblebee as it is 512MB big and slow net and PC wont stay on.

Also, xsensor shows my core temp to be more than 80° Celsius. Any tips?

Edit:

Q1.Output

ashwin@ashsek:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
powersave
ashwin@ashsek:~$

Q4. No Pc dosent heats in bios

I'm with Lenovo but I had similar problems like you, because of the Nvidia card and after the installation of bumblebee everything became normal. The bad thing with your laptop is the shutting down and I have two ideas which could give you time for installing bumblebee. First - Start the laptop and when you see the GRUB choose Ubuntu advanced options and after that Run in graphic safe mode. If your computer shut down again try the next thing. When the login box of Ubuntu appears click ctrl + alt + f1 and after that I hope you should have more time to install bumblebee.

But for sure don't forget to check the running processes in System Monitor.

Wish you Luck! :)

If you have overheating problems due to the nVidia card, I would:

  1. Disable the nVidia card in the BIOS or take it out of the PC
  2. Install 14.04.2 LTS (=Long Term Support)
  3. Install the nVidia modules (a.k.a. "drivers")
  4. Reboot and enable the card again

TLP brings you the benefits of advanced power management for Linux without the need to understand every technical detail. TLP comes with a default configuration already optimized for battery life, so you may just install and forget it.

To remove TLP,:
