    Lenovo P52 20M9 BIOS needed

    Hello
    I am in need of a BIOS dump for a Lenovo P52 with Xeon CPU and NVIDIA graphics
    The model Number is 20M9-CTO1WW
    The computer was force shutdown while an X86_64 port of Android was booting, and the machine did not restart after. I suspect firmware corruption as the CPU power rails look okay

    Thanks!

    Excuse me while i do something dangerous


    You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.

    Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

    That should still be under warranty.
    Get Lenovo to fix it. BIOS is not supposed to get corrupt merely by shutting down while it's booting an OS. (if it was performing a BIOS update that's something else though)

      It is out of warranty as of 10/19, sadly

        Ah… Sorry I assumed it came with 3 years base warranty as all Thinkpads in Europe but I guess that's not the case in the USA. Really worth it to have more than 1 year warranty on such a high value product.

              P52-MMX25L25.bin is the main BIOS chip

              P52_W25Q80.bin is the other small flash chip. Was connected upside down at first, so may have been damaged and the dump may be bad.


              Thanks!

                Try this bios, i`m unsure it will work though,can`t find a working bios dump to compare with.

                  Unfortunately no change.

                  I'm starting to suspect the CPU itself has failed as well.

                      Re: Lenovo P52 BIOS needed

                      Another bios for you to try. I copied the ME firmware from the RecoverDisabledPlatform_12.0.35.1427_v2 folder, (downloaded from the second link above) into your bios, there`s no more error messages now from MEAnalyzer .
