    Didn't try this. Odd that it'd be required if it worked before, but hey.
    Any one you suggest for P775TM1 with GTX 1080 and i7 8700K? Perhaps I should also try asking my reseller before trying anything here?

    First ask your reseller indeed

    Ok, I updated EC and BIOS given to my by the reseller. Installing it was some of the more stressful times as it refused to work after (note to self: never do it before your holiday lol), but after a long CMOS reset and followed keyboard fixes (I guess I unplugged it by accident), I eventually got it into working order - phew.

    Unfortunately, it didn't fix screen brightness neither keyboard backlight. Obsidian-PC still reports brightness as -1%, and keyboard backlight still doesn't react.
    The reseller suggested I install CCC now. Any suggestions I can try before trying that? Would like to avoid reinstalling OS again if some other suggestion comes up.

    Take an image of the machine and try CCC?
