    Hello guys I really need your support because i tried to modify my bios and flashed it and after that nothing worked anymore...
    My Thinkpad T480 doesnt turn on anymore and there are no lights, fan spinning etc... - so basically dead. The only thing working is when i plug it via AC then it charges.
    I flashed the bios Chip with a lot of other verions provided in this post and nothing helped unfortunalty.
    My Setup is the following:
    Lenovo Thinkpad T480
    Type: 20L6-S29E0C
    S/N: PP-1QC3TB
    Mainboard: i can"t tell you the exact Mainboard because i couldnt find any information about it on itself but i guess its ET480 NM-B501 as usual because i havent seen any other serial number for it.
    I would really appreciate the help because i really despair at this task.
    So if someone could help me and also need some more information i would love to provide them.
    (If its possible to give me an bios with a patched version (advanced menu, overclocking and erasing wwan whitelist) it would be even more perfect but not needed )
    I have no back up bios - because mine was broke and the only thing that matter is that my T480 will work again.
    Best regards and Thanks

    Thank you for your response and for your assistance.
    I attempted to patch the file you provided, but the issue persists.
    The system plays the startup melody followed by a blank screen (no display output).
    When I revert to the original file you shared, the device boots successfully, but the BIOS remains locked.

    Hi, I've been trying to unlock my T480's BIOS for over two weeks now.
    I followed all the instructions, tried AutoPatcher and other BIOS versions, but no luck.
    I found out that if the CRC check is wrong, the laptop plays a beep and shows a black screen. I fixed that issue, but now I'm stuck at a stage where the laptop just shuts down.
    If I restore the original BIOS, it asks for the password again and stays locked. What can I do???

    Type: 20L6-SDR213
    Serial No: PF-14H8HB
    Bios N24ET77W (1.52 )

    Just a question, by unlocking the advanced bios menu you can exceed the temperature limit of the GPU and CPU?
