I have been using Ubuntu 12.04.3 for about a month and half. I noticed that my laptop was always overheating which I found out was due to graphics drivers not being installed while searching on the internet. So I tried installing the graphics drivers through terminal following the guide on : https://help.ubuntu.com/community/BinaryDriverHowto/ATI. I didn't test it out immediately whether if it was working fine but instead it hasn't caused this issue.
Please if there is anyone with some knowledge about this I would be greatful for some advise..
Some info about the laptop : HP pavilion dv6 with an ATI graphics card and its dual booted with a Windows 7.
