I have noticed it several times that my system won't go into any of the power states like suspend or hibernate according to the rules set in Power management settings. The battery icon will be stuck in ac-plugged in state where as on expanding it, it would show the battery is discharging. This is very bad because system will eventually shut down and I will lose all my work. Reproducible: Sometimes Actual Results: Power management settings are ignored. System doesn't go into suspend or hibernate as per power management settings. Battery icon shows charging where as on expanding it shows discharging. System suspends and hibernates fine via Plasma menu options or via systemctl but not automatically as per power management settings. $ upower -d Device: /org/freedesktop/UPower/devices/line_power_AC native-path: AC power supply: yes updated: Wednesday 13 April 2016 09:31:19 AM IST (16286 seconds ago) has history: no has statistics: no line-power warning-level: none online: yes icon-name: 'ac-adapter-symbolic' Device: /org/freedesktop/UPower/devices/battery_BAT0 native-path: BAT0 vendor: SANYO model: 42T4763 serial: 13920 power supply: yes updated: Wednesday 13 April 2016 02:02:33 PM IST (12 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: discharging warning-level: none energy: 13.07 Wh energy-empty: 0 Wh energy-full: 27.43 Wh energy-full-design: 47.52 Wh energy-rate: 0.415 W voltage: 11.234 V time to empty: 31.5 hours percentage: 47% capacity: 57.7231% technology: lithium-ion icon-name: 'battery-good-symbolic' History (charge): 1460536353 47.000 discharging History (rate): 1460536353 0.415 discharging Device: /org/freedesktop/UPower/devices/mouse_0003o046DoC52Fx0002 native-path: /sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1/2-1.1:1.1/0003:046D:C52F.0002 vendor: Logitech, Inc. model: M185 serial: 03E8C0B4 power supply: no updated: Wednesday 13 April 2016 02:02:33 PM IST (12 seconds ago) has history: yes has statistics: no mouse present: no rechargeable: yes state: unknown warning-level: none percentage: 70% icon-name: 'battery-missing-symbolic' Device: /org/freedesktop/UPower/devices/DisplayDevice power supply: yes updated: Wednesday 13 April 2016 02:02:33 PM IST (12 seconds ago) has history: no has statistics: no battery present: yes state: discharging warning-level: none energy: 13.07 Wh energy-full: 27.43 Wh energy-rate: 0.415 W time to empty: 31.5 hours percentage: 47% icon-name: 'battery-good-symbolic' Daemon: daemon-version: 0.99.3 on-battery: no lid-is-closed: no lid-is-present: yes critical-action: HybridSleep

Same exact issue - on Neon Xenial running Plasma 5.13. `acpi` and `upower` will show the battery charge/discharge status correctly responding to AC plug on/off events, but the plasmashell battery icon will remain on "plugged in" mode even if I unplug. Strangely, sometimes the battery icon will still say "plugged in," even though when I click on the battery, it still says "discharging". Screenshot attached below.
Created attachment 113771 [details] Battery inconsistency Note the tray icon still has the battery in AC mode, even though it is listed as "Discharging" in the panel. More importantly, the power management settings still respond as if the AC were plugged in. I want it to auto-suspend only if battery is discharging and not suspend if AC is plugged in. The result here is that it thinks the AC is plugged in, discharges, and drains the battery.
Created attachment 113772 [details] All charging One more - now things are plugged in. Note that the tray icon is "charging", and now the battery icon in the panel dropdown is also "charging." In the previous screenshot, the battery icon in the panel dropdown was the normal "discharging" battery. However, crucially, in both cases, the battery tray icon was charging -- even though it is only really charging in this one and not the last one. The tray icon seems to dictate which power management behaviors are followed, so that it always does AC mode even if discharging.
Finally, I note the problem may result from a discrepancy between upower and acpi. Note the following terminal results. Both of these are in the state where the AC is not plugged in, but the tray icon still says discharging (even though battery panel icon says discharging): $ acpi -V Battery 0: Discharging, 50%, 01:55:40 remaining Battery 0: design capacity 5006 mAh, last full capacity 4092 mAh = 81% Adapter 0: off-line <----------------------------------------- NOTE HERE Thermal 0: ok, 40.0 degrees C Thermal 0: trip point 0 switches to mode hot at temperature 240.0 degrees C Thermal 1: ok, 35.3 degrees C Thermal 1: trip point 0 switches to mode hot at temperature 60.0 degrees C Thermal 2: ok, 0.0 degrees C Thermal 2: trip point 0 switches to mode hot at temperature 97.0 degrees C Thermal 3: ok, 38.0 degrees C Thermal 3: trip point 0 switches to mode hot at temperature 54.0 degrees C Cooling 0: x86_pkg_temp no state information available Cooling 1: Processor 0 of 10 Cooling 2: Processor 0 of 10 Cooling 3: intel_powerclamp no state information available Cooling 4: pch_skylake no state information available Cooling 5: Processor 0 of 10 Cooling 6: Processor 0 of 10 Note that Adapter 0 is offline.

Sorry if there is a better place to report this but cold not find any more recent bug report on this issue. Sometimes my battery indicator in sys tray still says "plugged in" (and the icon has the power plug in it) even though I have unplugged the power adaptor . When hovering the mouse over it, it says "Plugged in but still discharging". When clicking on it, the indicator says, "discharging", and the battery icon inside the popup window is the correct one (i.e. without the power plug in it). See screenshot attached. The issue is that he system does not go to sleep any more. For info, I have rule to stop charging at 85% and start at 45%. I "think" the issue happens after a wake up from sleep but I'm not sure and it is a bit random. Plugging back the power adaptor and unplugging it does not solve the issue. The only thing that seem to solve it is rebooting (then it works fine). I saw the issue being reported here too: - https://www.linuxquestions.org/questions/slackware-14/plasma-5-systray-battery-monitor-incorrectly-says-plugged-in-4175671626/ - https://forum.manjaro.org/t/battery-icon-is-constantly-in-charging-mode/27605 - https://bbs.archlinux.org/viewtopic.php?id=236409 (in here it says it is a bug in upower, but I cannot test that as I cannot downgrade to the version proposed in the article - I run upower version 0.99.11) - https://www.reddit.com/r/kde/comments/mxampb/having_a_few_problems_with_kde/
