[Trisquel-users] Use battery 1 before battery 0?

[jbahn]

I'm on a T400s with an extra battery in the ultra bay, i.e. instead of the  
dvd drive. The computer seems to be using the main battery (battery 0) first.  
When it is drained, the second battery (battery 1) takes over. Is there a way  
to a way to tell the computer to first use battery 1 and then battery 0? In  
that way I could have an extra fully charged battery in my bag and replace  
the drained battery from the ultra bay with the fully charged one, while the  
main battery would have taken over.
