This happens for me. Linux 4.15.0-34-generic #37-Ubuntu SMP Mon Aug 27 15:21:48 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
I'm running Linux Mint 19 Cinnamon 3.8.9. If I disconnect power, remove the back cover, disconnect both the main battery and the backup battery, I am able to get power status updates (e.g. battery will show as charging/charged when plugged in, or just regular battery when not). Once I sleep, I have to repeat this process if I want the battery status to work again. `acpi -p` correctly shows the charging state, but `tlp-stat -b` does not. `acpitool -ab` shows when unplugged, Battery #1 : Charging, 100.0%, 00:00:00 AC adapter : off-line and when plugged in: Battery #1 : Charging, 100.0%, 00:00:00 AC adapter : online Note: Battery charge percentage does work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/971061 Title: acpi reports battery state incorrectly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/971061/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
