Created attachment 123340 [details] Battery showing 0% charged at 100% SUMMARY org-kde-powerde shows incorrect battery percentage (0%) sometimes (after a reboot) and a successive reboot fixes this bug. If I'm on battery, laptop immdediately powers off but it doesn't do that on AC. I installed fresh kubuntu on this laptop and saw this same bug. OBSERVED RESULT Happens like every 4th reboot (not so rare). EXPECTED RESULT Didn't use to happen on my old laptop. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Yes(Arch) (available in About System) KDE Plasma Version: 5.17.0 KDE Frameworks Version: 5.63.0 Qt Version: 5.13.1 ADDITIONAL INFORMATION Observed on DELL Latitude E5540. I changed my laptop but didn't change the SSD(put old laptop's SSD into this one).
It appears to be a upower bug. I ran upower -d after seeing the same bug (the empty battery icon, this time without a restart) and this was the result: Device: /org/freedesktop/UPower/devices/battery_BAT0 native-path: BAT0 vendor: Samsung SDI model: DELL P8TC727 serial: 57965 power supply: yes updated: Sat 19 Oct 2019 08:40:39 PM PKT (104 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging warning-level: none energy: 0 Wh energy-empty: 0 Wh energy-full: 48.84 Wh energy-full-design: 48.84 Wh energy-rate: 0 W percentage: 0% capacity: 100% After a minute or two, the battery icon changed to full and I ran upower -d again and got this: Device: /org/freedesktop/UPower/devices/battery_BAT0 native-path: BAT0 vendor: Samsung SDI model: DELL P8TC727 serial: 57965 power supply: yes updated: Sat 19 Oct 2019 08:42:51 PM PKT (36 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging warning-level: none energy: 47.7633 Wh energy-empty: 0 Wh energy-full: 48.84 Wh energy-full-design: 48.84 Wh energy-rate: 1.6095 W voltage: 12.586 V time to full: 40.1 minutes percentage: 97% capacity: 100%
