jeffbellamy Posted October 10, 2020 Share Posted October 10, 2020 There is a battery on the board to maintain your CMOS.

Would need to see the DSDT/ACPI dump to tell Edit: This post is several months old as well - It's likely already been solved or there won't be a response Edited October 10, 2020 by 1Revenger1 Quote Link to comment Share on other sites More sharing options...

vokhotnikov Posted October 12, 2020 Share Posted October 12, 2020 IMHO, the presence of a battery (from the OS point of view) can be affected by: a) selected SMBIOS, but the OP mentioned iMac19,1 which is a desktop one b) DSDT contents. I would start with searching DSDT for a device like BAT0 or some such. If you find one can - you can rename it with bootloader patching, or supply a custom compiled DSDT.aml without it - at least to check if it would help.
