Comment 6 for bug 294021

Ok - well, I may just go ahead and look into this with the ACPI code. Did
you do this before with Hardy? I don't like the idea of having
swap/move/push etc. any batteries in my laptop unless it is absolutely
necessary. My machine (HP NC8000) has two dedicated battery bays that should
draw down power simultaneously or sequentially in Ubuntu. I just need to
figure out a way to manipulate ACPI to do this until a permanent fix is
released. The problem is when the primary battery runs low, Ubuntu won't
switch over to the other in-bay battery until I remove the primary and so I
just slightly pull out the primary battery until I can plug in the laptop to
run on AC power.
