Created attachment 280741 [details] kernel logs Battery percentage stuck as "estimating" when booting from the newly released kernel ( 4.20 ) and the system does not suspend after closing the laptop lid. The problem started with the 4.20.3-200.fc29.x86_64 it was working fine before. everything works fine when booting from an old kernel. I reported this on redhat bugzilla, and they instructed me to report it here.

Problem still persist in 4.20.5
problem persist in 4.20.10 I really hope someone will take the time to look at this bug
problem still exist in linux kernel 5. a more useful description ever since 4.20 the battery AML code completely fails to read from the hardware and returns some hardcoded fallback values for things like design-capacity and 0 for everything else.

The latest kernel that does not have this problem is 4.19.x Yup the problem still exists in 5.0.x (both fedora and opensuse TW)
please attach the output of "grep . /sys/class/power_supply/*/*" in both good and bad kernel, and the dmesg output after the above command.
