Hello,

I have installed a new laptop on a HP ProBook 6360b and for a while
the acpitool reported the correct state of the battery. But today it
started to report "Unknown, 97.00%". Charging the battery for hours do
not update the percentage.

If I disconnect the battery then acpitool correctly display
discharging and the percentage is decreasing (but the time remaining
is not computed because it stays at 00:00:00).
