>          until your battery indicator shows red colour and let's say 5%

IMPORTANT addition:

to check, if the battery profile is reliable enough: 
https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/135548/comments/100
from Joakim Andersson:

"... You can check the progress by right clicking g-p-m in the system 
tray, selecting "power history" and then in that box (near the bottom), 
select "discharge time accuracy profile". when the average value of that 
graph is over 40%, stuff will start working..."

Take care
