    Lenovo x390 8th Gen

    Hi,

    For some time I fight with a Lenovo x390, FT491/FX390 NM-B891 Rev:2.0
    I get it with missing bios if and thunderbolt ic.

    I brought new ic's and tested some bin files from forum,
    I don't know if they are good or bad…

    As I see on forum many has problem with the computer after they unlock bios.

    Mine, doesn't start. Power led blink's 3 times when I put charger but doesn't power up. Tested button, also short pin 3 and 4 from board, but no luck….
    No video, no sound, no fan spin.

    Does anybody had this problem and solve it?

    I also checked main rails and they are fine, I get correct voltages…

    Thanks!
    Stefan
