So when I got my Asus X32U Notebook, the first thing I did was delete windows and install 64bit Ubuntu 12.04 - which works great, however I only get around 2.5 hours on battery - nothing close to the advertised 10 hours.
What settings or configurations can I use/adjust to improve this?
I looked at the BIOS settings online, and really there is not much you can do. Also I do not have Ubuntu running on a laptop handy at this time, but I can tell you from experience what you can do. (these are personal suggestions).
Optimizing battery life helps you get the most out of battery operation, prolonging the charge/recharge cycle and improving recharging efficiency. You are advised to follow the suggestions set out below:

Use PowerTop.

not enabled these settings.1
