UPower and battery indicator show wrong information on fully charged ASUS Vivobook X510UR laptop

[Alexandre Forte]

When the ASUS Vivobook X510UR laptop is completely charged, the correct information is displayed on Windows. However, Ubuntu 18.04.2 LTS is unable to detect the true battery state. The GNOME battery indicator usually shows "Estimating..." or "Not charging", when the battery is at 100%.

If you use the upower version 0.99.7-2ubuntu0.18.04.1 command "upower -i /org/freedesktop/UPower/devices/battery_BAT0", this is what you get:

The "state" should be "fully-charged", but instead it is "pending-charge".

Thank you for your bug report, what's the content of /sys/class/power_supply/BAT0/status?
Also do you have the updates from bug #1745032 installed?

[Alexandre Forte (akf98)]

The system is up to date, so I think I have the updates installed. The content of /sys/class/power_supply/BAT0/status is "Not charging".

[Sebastien Bacher (seb128)]

"Nor chargning" seems to be the real state/what the kernel reports there then, it's similar to what is described in https://gitlab.gnome.org/GNOME/gnome-control-center/commit/6efaf85e
Not a bug?

[Alexandre Forte (akf98)]

I think it's a bug, because all laptops I've ever seen show "fully charged" instead of "not charging" when they hit 100% of the battery. And there's some other strange behavior, like the Gnome indicator eventually being stuck at "Estimating" and, sometimes, if you disconnect the power plug while at 100% and connect it again after that, Upower shows "discharging", as if it didn't recognize the power supply again, which is only fixed by a reboot.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

Been trying for days to 'fix' the battery status, 9.7 hours to full? think ubuntu is on crack

kali is detecting the battery fine, its ubuntu.

[Akash Banerjee (neail)]

The only fix found is--

shutdown > unplug the charger > remove the batt > reset the CMOS mem by holding the powerbotton for around 10 to 15 sec > replug batt > boot to ubuntu > plug charger.
