I had been really really screwed up as I was not able to optimize my laptop battery life.
I'm having Windows 7 - Pro and Linux Mint 13 - Maya in dual boot. Yes, I switched to Linux Mint after lot of head-banging with Ubuntu 12.04 with freaky Unity. So this is it. With Linux Mint 13 Mate variant now.
Alright. Now, I had hell lot of problems lined up with DELL Vostro 3460 to customize it my own way.
Battery was lasting for nearly 5 hours with Windows 7 Pro, but that wasn't same with Mint. I had to struggle a lot to find out ways how can I optimize my laptop battery. Mint would last for merely 2 hours. That was really annoying. So many optimization options were not really helping me. Like installing laptop-mode-tools, disabling unused services for every boot-time, and what not.
And even after all that, powertop showed power consumption to be ~ 25 Watts.
Moreover, without ANY application open after just logging into the system. :-(
I was so annoyed that, after thinking of changing distro to ArchLinux, Debian, Fedora, CentOS, I even thought to format laptop and stick to Windows 7 - pro. :-(
I had anyway paid for Windows 7, so why not just focus on it.
Anyway let the rest of story rest in peace. :-)
After lot of head-banging, I figured out that its Nvidia drivers who is culprit behind all this. I saw people saying, "if you had to install Linux on laptop, why go for optimus Laptops."
But this blog post saved me hell lot of battery life:

Thank you so much man.
Now, powertop shows merely 10 Watts after logging into system. :-)
I thought of creating a Bash script for lazy bunnies, but then it has a github download link for which version might differ as well. So, that is it!
What do I say to Nvidia when Linus can say that better. :D
..............Done!!!
