    Microsoft 15" Multi-Touch Surface Book 3 not turning ON

    Hello guys I have Microsoft 15" Multi-Touch Surface Book 3, it not turning ON, when I press the power button keyboard backlight flashes and goes away.

    I opened the machine, I did physical inspection, I have 3.3v on the board, I haven't checked for the other power rails since I don't have the schematic and board view, the board is different from laptops that we know, there is cpu and some other relevant chips but guys too this is challenging

    I have a feeling that the bios is corrupted but again I don't the bios files to flash the bios chip

    please advice
