Public bug reported:
Hi, Ubuntu 20.04 is not detecting changes form AC to battery correctly
in my Lenovo Thinkpad T490, when the power source is connected or
disconnected the following error appears:
ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.RP09.PEGP.NVDN],
AE_NOT_FOUND (20200528/psargs-330)
ACPI Error: Aborting method \_SB.PCI0.LPCB.EC._Q27 due to previous error
(AE_NOT_FOUND) (20200528/psparse-529)
Seems to be the same or similar issue at the ones described here:

from-ac-to-bat/19906 and here:
