Comment 161 for bug 971061

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.
