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

I'm not sure how libreboot handles UltraBay batteries but according to this  
wiki the regular BIOS actually first depletes the UltraBay battery before  
using the normal battery. You might find the settings you are after in the  
wiki as well.

Maybe this bug is relevant too?
