hal reports 100% remaining for an empty battery

[Iain McFarlane]

Hi,

I have noticed that when one of the two my batteries in my laptop empties (battery.charge_level.current = 0) the battery.charge_level.percentage = 100

This is on kernel 2.6.24-rc5.1mdv (Mandriva Cooker kernel) using hal 0.5.10

this is the output when fully charged:
udi = '/org/freedesktop/Hal/devices/acpi_C18C'

Any ideas?
