Title:
Problems Reading Battery Values
Status in upower package in Ubuntu:
New
Bug description:
I'm experiencing a variety of problems that appear related to
communicating with the battery in my HP Dragonfly Elite AMD Ryzen
7736U laptop.
In Gnome, the battery indicator will change values sharply like from
99% to 0% or the battery icon will disappear. If I'm connected to the
power adapter, sometimes it will return back to the previous
state/value after some time. If I'm not connected to the power
adapter, it might say that it is about to hibernate or shutdown and
then may hibernate or shutdown.
acpitool -B has at times failed to show any battery present. It
normally presents output like:
Battery #1 : present
Remaining capacity : 58490 mWh, 100.0%
Design capacity : 65000 mWh
Last full capacity : 58490 mWh, 89.98% of design capacity
Capacity loss : 10.02%
Present rate : 0 mW
Charging state : Full
Battery type : Li-ion
Model number : PABAS0241231
Serial number : 41167
At least once, none of the processor cores would clock above 400MHz
according to /proc/cpuinfo while in this state.
I don't know if this is (just) a hardware problem (the HP Diagnostic
hasn't provided me with an error code but the BIOS has at times failed
to detect the battery) but there are log messages in /var/log/syslog
which say "please report!" (hence this report).
