This first image before (u ask about not understand is answer to ur note about "old" bios) and this phote i do before i do post before this post
, just reaction to ur post about bios.. and ofc this photo from start this tool, but bios updated more than 3-4 hours before i make a first report.
Anyway, here is a new report, include again new error message after screen goin black again and i restart notebook. This black screen happend sometimes now, no idea why, maybe a battery low? one black screen during boot when i put AC adapter in, one black screen after i am inside High Sierra puttin out a AC power. System works with battery, with AC adapter, but any work with this and system goin black. Only restart help, sometimes need verbose mode for working boot (prevent loop boot).
BEFORE i make a report, from clover i use F1 key (for sure F-keys working corect) after this one times i use F2 and after that F4 key. After boot into system, i just start script and make report inside zip (debug_2369.zip)
