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 6 '12 at 13:47

Jupiter might not be enough. –  VedVals Dec 4 '12 at 9:24

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.
