I have tried to trigger it again and watched journalctl's output, maybe it gives a clue: ``` --> Unplug No log.

If so, then it's a kernel bug: https://bugzilla.kernel.org/show_bug.cgi?id=210425 (In reply to Nate Graham from comment #2) > Is it 100% reproducible when you unplug your laptop while it's > asleep/suspended? If so, then it's a kernel bug: > https://bugzilla.kernel.org/show_bug.cgi?id=210425 Nope, it happens too, when it's suspended, but it's not 100% reproducible unfortunately. You mean, it also happens then it's *not* suspended as well? (In reply to Nate Graham from comment #4) > You mean, it also happens then it's *not* suspended as well? Right! It also happens while I am working or the system is idling but not suspended. (Sorry, I wish I could edit messages here as sometimes something comes to my mind a moment later after I have posted already.) Nonetheless, I feel you may be right and it's likely to be a Kernel bug and Plasma/powerdevil cannot do anything about it. I may report it at bugzilla.kernel.org too.

udevadm monitor -k
The Kernel is obviously always notified about changes to the power supply, even when the bug happens.

Thanks for the info. I'm a bit out of my depth here, but does that mean that you think the kernel and udev are doing their part and the problem is in powerdevil?

Could be, but I will have to investigate more in depth next month, when I have more leisure time. Anyway, I will come back to it and adjust the bug report accordingly. Powerdevil does not handle directly battery state monitoring and relies on upower to do that. You can compare your results with "upower -d" and "upower -m" (monitor), and probably can report a bug there. https://gitlab.freedesktop.org/upower/upower/-/issues/22 seems like a good candidate. For reference we had a similar bug considered to be an upstream bug. https://bugs.kde.org/show_bug.cgi?id=423556 But it seems upstream upower could benefit from your help in diagnosing the bug.

Git commit 01df6cf933c1a48928ff72af7cb520183130ff05 by Méven Car. Committed on 20/10/2021 at 09:47. Pushed by meven into branch 'master'.

I still face this bug, and it makes it difficult as now the laptop does not suspend when I close the lid as it thinks it is plugged in. Could anyone please comment on whether this is resolved Thanks! It's the same issue as Bug 423556, which is an upstream issue. See https://gitlab.freedesktop.org/upower/upower/-/issues/126.
