you can use dconf-tools(also known as dconf editor):
install it by
sudo apt-get install dconf-tools (in terminal) or get it from ubuntu softwARE center .
Press alt+f2 and open dconf-editor (or in a terminal type dconf-editor)
Navigate to Navigate to org>>gnome>>settings-daemon>>plugins>>power and set your default button-power action there.
I hope this will help you.
