Hi Michael,

thanks for caring :-)

Yes, the problem seems to be the same as reported in bug #405216. My laptop is 
an Acer, too, and the present voltage is 1mV just as in #405216. Here's the 
battery information:

$ cat /proc/acpi/battery/BAT1/state
present:                 yes
capacity state:          ok
charging state:          discharging
present rate:            1901 mA
remaining capacity:      2974 mAh
present voltage:         1 mV

Here's what I got from lshal:

97% directly after unplugging. A minute later I got 100% (strange, isn't it). 
Next, step is 75%, then 50%. (I stopped here)

Why does HAL need to recalculate the charge_level.percentage at all when it is 
already provided by acpi? Shouldn't they (acpi and lshal) report the same 
values anyway? 

Kind regards,

Felix
