jeffbellamy 5 Posted October 10, 2020 Posted October 10, 2020 There is a battery on the board to maintain your CMOS. Here is a link to instructions on getting to your battery: https://www.joinfu.com/2018/06/how-to-reset-cmos-on-gigabyte-brix/ Quote Share this post Link to post Share on other sites

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 Share this post Link to post Share on other sites

vokhotnikov 0 Posted October 12, 2020 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.
