It has ended up with a ticket to kernel bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=206731

I have a Lenovo Ideapad 330-17ICH laptop running Ubuntu 19.10. Since I've installed Ubuntu 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. I've tried Ubuntu 18.04, Linux Mint etc and on each I have the same problem. I've tried Windows for a second and there charger is recognized instantaneously.

Currently, instead of swapping over different systems distros I'm trying to fix this problem here, on Ubuntu.

The very first thing I've tried is to install another kernels - I've tried 4.14 (as there are some incompatibilities on 4.15 - 4.19 with my laptop), 5.5.4 and now running on 5.3.0. On each of them I have same similar.

Here are the logs:

  • I've grepped over the boot logs for ACPI, and here's the result containing ACPI:
  • And here's full syslog just from boot:
  • The command grep . /sys/class/power_supply/*/* output
  • dmesg
  • acpidump

From all of that, those logs seems to be pretty meaningful:

Feb 19 19:48:24 domin kernel: [    0.344417] ACPI BIOS Error (bug):

Feb 19 19:48:24 domin kernel: [    0.344551] ACPI: Skipping parse of AML opcode: Scope (0x0010)

but Google search results say it's all about too new hardware.

Do you have any ideas where can I look further?

EDIT1: I've upgraded Bios to the latest version - no changes occurred
EDIT2: added dmesg, acpidump and result of grep . /sys/class/power_supply/*/*

    Could you please provide the output of grep . /sys/class/power_supply/*/* and the dmesg output after that? Feb 27, 2020 at 23:51

    The output of acpidump may be useful too. Feb 28, 2020 at 0:07
  • ACPI tables! Is it a good idea do dump acpitables from Windows and import them on Ubuntu? @AlexandreTeles I've updated the post with outputs.

    You could try, but I honestly can't see anything wrong with battery management in your dumps. It's either something with the Ubuntu's kernel compilation/version or with the Kernel itself. This isn't the first problem of that kind I see and you can find problems like bugzilla.kernel.org/show_bug.cgi?id=44161 present in the kernel for literally years. I would probably open a ticket on Ubuntu and the kernel bug tracking systems with those logs. Feb 28, 2020 at 20:10
  • ok I'm going ahead and it will end up with a ticket to both kernel tracking system and Ubuntu. I've talked to a friend who has simiar hardware and he has the same problem when he installed Ubuntu
