Title:
Regression: acpi reports battery state incorrectly after sleep
Status in linux package in Ubuntu:
Expired
Bug description:
On Samsung Series 9 laptops the battery state and the charger status
are incorrectly reported in kernel 4.15.
This bug is a regression: it has been fixed in 2012 [1] it used to
work fine until Linux 14.10 (included).
Quoting Matthew McCallum from

> 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.
