    HP 17-CB0534SA BIOS MPM/BCU Help please

    Hi All,

    I have an HP 17-CN0534SA laptop which has had a motherboard swap. When looking at the BIOS data for the Serial Number, Product Number etc is all listed as "N/A". I have used BCU to try and update the data however all I receive if Error Code 6 - Access Denied when I attempt to write back ANY values (this includes trying to change the MPM flag). I think the BIOS is locked, but I am not sure how to unlock it?

    Please could any of you help?

    HP Model - 17-CN0534SA
    Product ID - 88Z23EA#ABU
    Serial - 5CG3321XZZ

    BIOS Dump attached

    Many thanks in advance

      Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
      by Wahaz
      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....

      ASUS TP500LA BIOS request/repair/merge?
      by jbonavita
      Hi, my laptop wont boot at all
      With original bios no POST, only LED lights
      With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
      Some issues
      A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
      B- If updated from 500LN version 203 to 300, the battery stops being recognized

      Things I tried

      1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

      [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
      by zenius
      Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

      Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

      Changing BIOS Serial Number After Motherboard Replacement on EliteBook x360 G3
      by Friend33
      Hello,

      I have an EliteBook x360 G3 where I had to replace the motherboard. Everything is working fine and there are no errors during boot. However, I have the issue that the serial number in the BIOS is incorrect. When I run the DMI tool under Windows, I get an error stating that I am not in Unlocked Mode and therefore cannot make any changes. I was able to change the Asset Tag directly in the BIOS. Now I am wondering, can I simply read the BIOS chip, change the serial number with a hex editor, and write it back, or what other options do I have? The old motherboard did not work at...

      [HELP] G712LWS BIOS capsule
      by TraJikar Mac
      I need someone that can capsulate one of the bios files below, and i prefer the older bios version so i can flash it using CH341A tool into the bios chip.
      The manufacturer BIOS files are bigger than the BIOSbackup1.bin files by 256KB and I don't know how to fix or recompile it.

      You can see in this link a conversation between me and other people (Starting at page 10) who tried to help me (thanks to their efforts), but i still couldn't fix it and the laptop is considered as dead until now.

      Also, I uploaded a backup file for the bios that I extracted by using CH341A...
