Bug#785413: Battery always charging on Acer C720P
Package: linux
Version: 3.16.0-4
Hello,
I am running Debian testing on an Acer C720P (amd64), and I am seeing a
strange behavior. When I charge my battery, it is never reported as
completely charged by the system. The notebook's led keeps indicating
that the battery is being charged, and when I look at
mate-power-control's battery icon it also says that the battery is not
fully charged.
If I check the values on
/sys/bus/acpi/drivers/battery/PNP0CA\:00/power_supply/BAT0/*, I see
that:
1) It indicates that the battery's charge_now is equal to the battery's
charge_full.
2) It still indicates a "Charging" status.
I still have not investigated it further, so I am opening this bug
against the Linux package (it seems like an ACPI problem).
It is worth mentioning that I was running Fedora before I put Debian on
this machine, and the battery was charging normally there. Also, I
recently compiled the latest version of the Linux-libre kernel (4.0.3),
and I was seeing the same problem using it as well. This may mean that
(a) this notebook needs some kind of proprietary blob in this case, or
(b) some userspace program is the actual responsible for this (although
we should also consider the wrong "Charging" status on /sys, as
mentioned above).
You will probably need more specific information to debug this, so
please let me know what I must provide.
Thanks,
