I just installed Ubuntu on my HP Pavilion dv6-6c50ca, and I noticed that every time that I start my laptop with Ubuntu the fan runs really fast and the laptop produces a lot of heat. When I run windows on it, the battery life lasts for 4 hours but when I run Ubuntu, it barely lasts for an hour and a half no matter what I'm doing, even when I'm typing a simple word document. Here are my laptop specifications:

  • HD BrightView LED-backlit Display
  • Intel core i5 2.5 Ghz i5-2450M
  • 750GB hard drive 5400RPM
  • Video card: AMD Radeon HD 7690M XT
  • Battery: 6-Cell Lithium-ion

Here is a more detailed specification in case I left out anything important.

Thank you for your help!

  • Do you use the proprietary ATI drivers? – RolandiXor Sep 19 '12 at 22:30
  • Here's what showed up when I typed in that command: tedderic@ubuntu:~$ uname -a; cat/etc/lsb-release Linux ubuntu 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux bash: cat/etc/lsb-release: No such file or directory – Ted Sep 20 '12 at 03:26
  • And yes I'm using the 3D-accelerated proprietary graphics driver for ATI cards. – Ted Sep 20 '12 at 03:28
  • Still having this problem? Have you tried a newer version of Ubuntu? – Seth Jul 01 '14 at 20:50
