Bug#1114642: acpi: ThinkPad X1 Yoga: inconsistent/zero energy-full-design values for internal battery
Package: src:linux
Version: 6.16.3-1
Severity: normal
Dear Maintainer,
There is a possibility that my laptop's battery is in a degrated state of
health; if this issue is determined to be a hardware problem, then my apologies
in advance for time spent debugging.
Recently I have noticed that the battery power indicator in my GNOME desktop
environment frequently indicates a 0% charge level, despite the fact that the
laptop can continue without AC power for some time.
I've been using the upower utility (from the binary package of the same name)
to report in-use battery statistics, and receive inconsistent results.
The most recent results, as I write this, are shown below:
$ sudo upower -i /org/freedesktop/UPower/devices/battery_BAT0
native-path: BAT0

technology: lithium-polymer
charge-start-threshold: 75%
charge-end-threshold: 80%
charge-threshold-enabled: yes
charge-threshold-supported: yes
icon-name: 'battery-caution-charging-symbolic'
History (charge):
1757271651 0.000 unknown
History (rate):
1757271651 0.000 unknown
In previous boots of the system earlier today, I have encountered 0 Wh values
simultaneously for both the energy-full and energy-full design fields.
I do not recall encountering the 0% battery status indicator before upgrading
to Debian trixie -- however, it is also possible that the physical state of the
battery has degraded within that same time window.
Any help much appreciated,
Thanks,
James
