Title:
upower gives incorrect data/misleading data
Status in “upower” package in Ubuntu:
Confirmed
Bug description:
Binary package hint: upower
I am using lucid. I have a dell inspiron 6000
upower gives data that is inconsistent with acpi.
> acpi
Battery 0: Charging, 27%, 01:25:50 until charged
this agrees with the bios, so I believe it to be correct.
> upower --dump

the incorrect stat is percentage. Note that it is 18%, i.e. different
from what acpi reports. this battery is an older battery and only
holds about 65% of the design capacity when full. So, energy-full
seems to be wrong as well. I don't know what capacity is, but as I
said the last full capacity is about 2/3 of the design capacity, so it
could be that. In fact, 18%/67%= 27% agrees with acpi, so that is
probably what capacity means.
Anyways, this is causing my gnome-power-manager to report the wrong
charge as well.
