    I reverted back to the 850 g3 bios bin before attempting the BCU and it is stated I can't change the model because it is Read-only of which i still tried anyways with no luck . Right now, I am stuck. If i can get a working BIOS for 840 g3, it will be useful. One i have that works shows up as ZBook 14 G3.

    I bought a replacement motherboard which happens to be for HP Elitebook 850 g3 and i want to use it to replace a faulty HP Elitebook 840 g3 motherboard. I have attempted to transfer the model name and serial number from the faulty 840 g3 motherboard to the 850 g3 motherboard but it turned out unsuccessful. I tried using my knowledge of changing Apple SSN, HWC and Checksum on it and I was able to input the correct serial number and model name but wasn't able to rectify the checksum error. After putting the BIOS Chips back on the motherboard and powering on, it displayed CMOS reset page upon first boot and after pressing 'ENTER' key to restart, it didn't display again and started fan spinning.

    I will be glad if anyone here can assist me in sorting it out or direct me on how to fix the checksum for it.

    I have attached the original untouched BIOS bin for the 850 g3 and the modded BIOS [16mb and 8mb] as well. I have also attached the error i got from using ME Analyzer too

    Model: HP Elitebook 840 g3

    Board No: 6050A2892401-MB-A01

    Thanks.

    I need a BIOS dump for the Samsung S49CG934SU monitor
    by Habble7
    The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

    Suspected Cause:
    I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

    Troubleshooting Attempts:

    MSI PRO B660M-G DDR4 - real bios dump from board needed (no stock bios)
    by DynaxSC
    Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).

    I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...

    Elitebook 850 G5 BIOS bricked
    by Guest
    Hello,

    I have an EliteBook 850 G5. After a Windows update, including a BIOS update, the notebook turns on, but the screen remains black, and the fans spin at high speed—nothing else happens.

    I assume the BIOS update failed, so I searched for the BIOS chip.

    I found a Winbond chip located between the RAM and the hard drive, which has a size of 32 MB.

    However, the BIOS update available on HP's website is only 17 MB in size. I used the update version that was previously installed when the notebook was still working.

    Can the corrupted...

    This laptop is the same laptop I was working on in this thread and I wasn't sure if I should post a new topic or post in that thread because I already solved the issue that thread was discussing and this is a completely different issue although it is dealing with the same laptop. I decided to make a new thread since it's a new issue, but please move if I made a mistake.
