    Lightbulb G750JX Help navigating BIOS, Booting without Display - Solved

    Hey!

    BSOD and boot to BIOS resulted in a friend messing up BIOS settings and saving it. Now laptop boots without a working screen (external screen has the same problem). Funny thing is that this has happened before when I installed an SSD, the issue got fixed when I navigated blind in BIOS and changed "Secure Boot" and "Key Management" to default.

    With help of videos and pictures that I found, I know how to navigate and change "Secure Boot" setting but I have a hard time finding how the "Key Management" option looks.
    If any of you got this laptop series and can help out. I need a picture or a description of how the options look in "Key Management" tab.


    PS: they keys there might be important, blur it out.


    No, power cycling and clearing CMOS does not help or restoring BIOS to default.


    From what I remember it looks similar to this:

    Anyone?!

    Anyone with a G750 that can help me????

    I need to enable Secure Boot and load defaults in Key Management to have a working internal/external screen.

    If anyone can share a description/documentation of BIOS -> Security Tab -> Secure Boot ->/& Key Management.


    -- Here is an example WITH mistakes cause I can not find a description or a picture or a video:


    in "Secure Boot" window: 2 choices

    First choice: "Enable Secure Boot", 2 options (enable/disable)
    Second choice: "Key Management", enters a new window with 3 choices

    - Choice 1 - "Default Key etc" has 4 options (disable/enable/restore/reset)
    - Choice 2 - "Enroll All etc" opens a confirmations window (Yes/No)
    - Choice 3 - "I Will Help" opens a confirmation windows (Yes/Yes/Yes/Maybe/Yes)


    I am blind here

    Solved

    Gave it another go yesterday and solved it!
    .
    Problem wasn't with Key Management but with Launch CSM and Secure Boot Control.

    The FIX: Disable "Launch CSM" in "Boot" and enable "Secure Boot Control" in "Security>Secure Boot menu". F10 to Save & Exit.


    Lots of try and error to change those settings with no screen but it is doable with enough information.

    The headache is in the "Boot" menu settings, if "Launch CSM" is enabled then it's the first option in the "Boot" menu. If "Launch CSM" is disabled then it's the second option after "Fast Boot".

    Attached jpeg of how the settings look.

    Thank you all for the help.
