I recently got a new laptop, so I decided to use my old one as a home server. The problem is that it's rather power-hungry and I would like to make it more energy-efficient.

Would it be a good idea to turn off or disable most of the power of the GPU? How would I do this? Are there any other options?

specification

Graphics car: Nvidia geforce GT 560m 3gb
Laptop Model: Asus G74s
Ubuntu 14.04 LTS

Not sure about optimus. i Just wiped windows and clean installed Ubuntu

  • Can you give a bit more information about this computer? Does it have an Optimus configuration? What kind of graphics card? Please edit this in to your question. Thanks!

TLP is a power management tool for Linux. It brings you the benefits of advanced power management without the need to understand every technical detail.

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp

Run PowerTOP before & after to see difference. Power settings will be re-profiled by TLP upon fresh boot.
