I tried this in a 19.04 live boot from a usb stick and the behavior was correct: if the system was booted without power, the charging symbol was not there. Then when I connected the power, the charging symbol appeared.
Also, when booting 19.04 without power connected, there is only the one dbus-daemon line in journalctl: Sep 26 18:55:04 ubuntu dbus-daemon[1097]: [system] Activating via systemd: service name='org.freedesktop.UPower' unit='upower.service' requested by ':1.38' (uid=999 pid=1761 comm="/usr/bin/gnome-shell " label="u nconfined") So there is some regression between 19.04 and current 19.10. 19.04 kernel: 5.0.0.-13.14 19.10 kernel: 5.3.0-10.11 -- 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/1845532 Title: power icon does not indicate charging if booted without power connected Status in upower package in Ubuntu: New Bug description: Hardware: Lenovo T590 OS: 19.10 When the power is not connected when the laptop boots, and then connected, the power icon in the top bar does not change to indicate that the laptop is now charging. $ upower -d Device: /org/freedesktop/UPower/devices/line_power_AC native-path: AC power supply: yes updated: Thu 26 Sep 2019 08:53:40 AM MDT (2107 seconds ago) has history: no has statistics: no line-power warning-level: none online: no icon-name: 'ac-adapter-symbolic' Device: /org/freedesktop/UPower/devices/battery_BAT0 native-path: BAT0 vendor: SMP model: 02DL012 serial: 1417 power supply: yes updated: Thu 26 Sep 2019 09:28:33 AM MDT (14 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: discharging warning-level: none energy: 55.53 Wh energy-empty: 0 Wh energy-full: 57.21 Wh energy-full-design: 57.02 Wh energy-rate: 0.319173 W voltage: 12.932 V time to empty: 7.2 days percentage: 97% capacity: 100% technology: lithium-polymer icon-name: 'battery-full-symbolic' Device: /org/freedesktop/UPower/devices/DisplayDevice power supply: yes updated: Thu 26 Sep 2019 09:22:33 AM MDT (374 seconds ago) has history: no has statistics: no battery present: yes state: discharging warning-level: none energy: 55.53 Wh energy-full: 57.21 Wh energy-rate: 0.319173 W time to empty: 7.2 days percentage: 97% icon-name: 'battery-full-symbolic' Daemon: daemon-version: 0.99.11 on-battery: yes lid-is-closed: no lid-is-present: yes critical-action: PowerOff $ cat /sys/class/power_supply/BAT0/status Unknown However, if the laptop is booted with the power connected, then the battery icon in the top bar shows that it's charging and at 100%.
