Here is the output of acpitool -B while Gnome reports 0% battery: Battery #1 : present Remaining capacity : 58490 mWh, 100.0% , -1.000% of design capacity Capacity loss : 101.0% Present rate : 0 mW Charging state : Full Battery type : Li-ion Model number : PABAS0241231 Serial number : 41167
Despite being plugged in (and fully charged), some processes think there is low battery: 2024-02-10T17:32:01.406945-05:00 dragonfly tracker-miner-f[3211]: Running on LOW Battery, pausing 2024-02-10T17:32:02.406736-05:00 dragonfly upowerd[1950]: value "-nan" of type 'gdouble' is invalid or out of range for property 'percentage' of type 'gdouble' -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to upower in Ubuntu. https://bugs.launchpad.net/bugs/2052865 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).
