I have a Lenovo Ideapad 330-17ICH laptop running Ubuntu 19.10. Since I've installed Linux-based system I'm having issues with charger - it's not recognized instantaneously. After a while after connected (probably when battery level changes), it's recognized as "charging". The same is in reverse way - after a while it notices that charger was unplugged. On Windows charger (un)plug is detected promptly and instantaneously. This issue was checked at the following kernel versions: 4.14, 5.3.0, 5.5.4. All of them are affected. It was also detected on the another laptop with similar hardware and tested on the other Linux based systems e.g Linux Mint, Ubuntu 18.04, Manjaro. - here's full syslog just from boot: https://gist.github.com/Dominos/23e658b41fe90b7b08c172533b4b08e5 - The command `grep . /sys/class/power_supply/*/*` output: https://gist.github.com/Dominos/5ef9252a94c4a8805682eede87b73ec1#file-gistfile1-txt - dmesg: https://gist.github.com/Dominos/a2665146a4af228c97f74e1563ec8b7d#file-dmesg-txt - acpidump: https://gist.github.com/Dominos/41ade2cf5ea12a4a4db3aa730e1a85e5#file-acpidump_ideapad_330_17ich_ubuntu-txt - inxi -aF output: https://gist.github.com/Dominos/3f5480c01e80ed7e1d765d74bf0ad4e8#file-inxi Bios is updated to the latest available version.
Take a look at https://bugzilla.kernel.org/show_bug.cgi?id=207749, i guess it's the same issue according to your kernel log. Your syslog has an "irq 9: nobody cared" log entry after 15 seconds.
This is got from your acpidump [02Eh 0046 2] SCI Interrupt : 0009 so irq 9 is ACPI interrupt. please attach the output of "grep . /sys/firmware/acpi/interrupts/*"
