I have just started using Ubuntu. Loving the way it works but I am having issue with heating.

It is being heating more than it did when I had Windows 7 installed. Not sure if its problem of drivers as I have installed Drivers when it promoted for my Nvidia graphics card.

I have two graphics card, Intel HD 3000 and Nvidia one. Please help me with this. I think due to this heating issue I am also getting low battery backup. The battery drains much faster.

Lenovo Z570 12.04 LTS

Suggest you visit askubuntu.com/questions/267815/dell-d520-getting-hot-12-10 and see if your machine is stuck in 'performance mode' only. –  K7AAY Jan 9 at 21:33
    
Have you got bumblebee installed? I have a G570 or something similar I think and when I use the nvidia card it heats up a lot more than without it. –  don.joey Jan 9 at 21:54

Sucks, huh? I bought a laptop cooler. Actually, I went through a few of them (don't go cheap!!!!) until I found one that has, along with the obvious fans, little feet on the bottom that flip out about an inch. When sitting on a desk, this feature elevates the computer and the cooler so air can circulate beneath the laptop cooler. This little aspect is VERY important

My fan spins up whenever I play WOW or watch Netflix. This last cooler is a miracle worker. I don't have it just now, because I'm not at home, but I think it was from the Cooler Master brand.

For hybrid systems I recommend to update to Ubuntu 13.10 as it is the first release to fully support hybrid systems like yours.

For your overheating problem (uninstall all previous drivers you have):

sudo apt-get install nvidia-319 nvidia-settings-319 nvidia-prime

Then go to nvidia drivers setting page and set intel gpu for normal use. Prime is a package for hybrid systems like yours.

To extend the battery life greatly do the following:

TLP helps laptop reduce the ammount of power consumed in a much more efficient way than any other:

First: Uninstall laptop mode tools

sudo apt-get remove laptop-mode-tools

Then install:

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update 
sudo apt-get install tlp tlp-rdw

Finally start it:

sudo tlp start
