I installed recent Ubuntu version in my Acer 5755G laptop, it is over-heating. The laptop is in good condition,it'll not get heat while using windows 7. I think the problem with the graphics card. But as I'm new to Ubuntu i don't know how to solve the problem. So please someone help me.

Laptop Configurations:

  • i5 second Generation

  • 750GB HDD

  • 2GB nVIDIA graphics card

  • 4GB RAM

  • is your computer a hybrid graphics solution? You should check to get the correct graphics drivers for the machine, as I would guess that both cards (intel and dedicated) are running. If you are using the open source drivers, you should be able to use vga_switcheroo. What's the output of cat /sys/kernel/debug/vgaswitcheroo/switch? – onse Nov 06 '12 at 13:47

Use the nbfc

Mine is an Acer Aspire E5-573G laptop and nothing else worked to control the CPU fan, but nbfc. I'm using Ubuntu 18.04. The exact profile for my model is missing, but nbfc worked fine with another similar profile (Acer Aspire E5-575G). If you don't know which profile to use, you can try: mono nbfc.exe config -r

You will need the latest mono version to build it on Ubuntu 18.04, so don't forget to read How to build NBFC on ubuntu.

Also I edit the default profile to turn the fan policy more aggressive.

NVidia graphics card eats up a lot of power. You need Bumblebee to control power consumption. Installing it helped reduce my core temperatures and increase battery-life to about 3 hours.

Turn off the graphics card from BIOS
I am also using ubutnu 14.04LTS. Heating problem is almost all linux os has for those laptop having two graphics (integrated and dedicated like nvidia).
So,
The solution is turn off the graphics card from BIOS setting. This works for me and gives almost 3.5 hours battery backup and no more heating.

Tell me if it works for U.
