Install the drivers:

sudo apt-get install fglrx fglrx-pxpress

then open the amd catalyst control center and disable the 5650.

TLP helps laptop reduce the ammount of power consumed in a much more efficient way than any other:

First: Uninstall laptop mode tools

sudo apt-get remove laptop-mode-tools

Then install:

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

Finally start it:

sudo tlp start
