I am a newbie to Ubuntu (after dumping 3 other distros) and have seen a terrible battery management from Ubuntu.

I use a HP DV7 17" 8 gb ram beast with about 30 minutes of battery power since I switched to Ubuntu. On windows I had almost 2 hours of battery power. I use Ubuntu 12.04 due to it's LTS.

Need help please.

Thanks in advance.
