I think I mentioned that it is *not* a hardware problem apparently.

When I reboot with the power supply disconnected, the charge is up to 96 %
even after it had forced me to reboot after giving me a 0 % charge
notification.

I am quite certain that there is no "ghost" recharging it from 0 % to 96
% in the 1-2 minutes it takes to reboot, without a power supply connected :)
