Created attachment 292023 [details] ACPI dump Hello, I noticed the following kernel messages when I unplug the AC from my laptop Lenovo T490 (20RY-CTO1WW) running the Linux kernel 5.8.1 and the latest system firmware version 1.13: [10868.562198] ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.RP09.PEGP.NVDN], AE_NOT_FOUND (20200528/psargs-330) [10868.562210] ACPI Error: Aborting method \_SB.PCI0.LPCB.EC._Q27 due to previous error (AE_NOT_FOUND) (20200528/psparse-529) And when I plug it in again: [13493.320146] ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.RP09.PEGP.NVDN], AE_NOT_FOUND (20200528/psargs-330) [13493.320173] ACPI Error: Aborting method \_SB.PCI0.LPCB.EC._Q26 due to previous error (AE_NOT_FOUND) (20200528/psparse-529) However, I haven't experienced any problems because of that. For example, I see correct values returned by /sys/class/power_supply/BAT0/status. Dmesg and acpidump are attached. Thank you.
