When the Lenovo Ideapad 330s is running on battery, the following error message
is printed in the kernel log every second or so.
[ 0.967136] ACPI BIOS Error (bug): Could not resolve symbol [^^^GFX0.AFN2],
AE_NOT_FOUND (20200717/psargs-330)
[ 0.967173] ACPI Error: Aborting method \_SB.PCI0.LPCB.H_EC._QC9 due to
previous error (AE_NOT_FOUND) (20200717/psparse-529)
This does not happen when the AC adapter is plugged in, and the laptop does not
have other symptoms.
Does not seem specific to a Linux kernel version.
