Vincent, are you running a 2.4 or 2.6 kernel ?

I noticed the same kind of problem with 2.4 kernels after 2.4.20. It's
impossible to swap the battery with these kernels, the machine always

However, I can swap the battery with my current 2.6.2rc2 just
fine. Maybe there's something different in sleep code between 2.4 and
2.6 ?
