    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!
    Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

    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.

                              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.

                                      get in touch with lenovo and ask them if they`ll fix it for you,for free,there`s a major problem with the ME firmware updates on these

                                          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 .

                                                          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

                                                              Hello,

                                                              I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
                                                              So I thought it was a Bios problem.
                                                              I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

                                                              Hi everyone,

                                                              My Lenovo Legion Y540 (i7-9750H, RTX 2060) bricked after I downgraded from BHCN44WW to BHCN21WW.
                                                              Laptop stopped booting entirely.

                                                              I used a CH341A programmer to dump the corrupted 16MB BIOS.
                                                              i then attempted the following:
                                                              1. Downloaded stock BIOS BHCN39WW from Lenovo
                                                              2. Trimmed it to 16MB
                                                              3. Extracted the BIOS region from the corrupted dump
                                                              4. Extracted the BIOS region from the stock 39WW
                                                              5. Replaced the corrupted BIOS region with the stock one (within hxd , opened the corrupted dump and replaced its region by the stock)
                                                              6. Injected back my LDGB / DMI

                                                              I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.

                                                              History:

It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.

                                                              I searched for this error online and discovered...

                                                              Hello everyone,

                                                              I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

                                                              This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

                                                              I have opened the laptop and identified the main BIOS chip...
