    Hi
    I brought a replacement motherboard for my HP EliteDesk 800 G1 USDT from eBay can someone tell me how to change the serial number in the BIOS to match the old one (original serial number: CZC33038TC)?

    I have attached a copy BIOS copied using a CH341A programmer

    Many thanks

    John

    Hi

    I tried the modified bios this morning unfortunately it didn't work and kept the original serial number from the new motherboard. Anything else we can try?

    Thanks again for your help

    I have a Elite x2 1012 G1 and I can access the os and I am the admin but I can’t update bios because there is a person there? I just need to access it so I can update with newest bios. What do I need to do? Change Bios? Or remove pw? And what file and program do I need to accomplish this? Thanks in advance.

    Sounds complicated. I need an eeprom reader? I will see what I can do. I was hoping there was easier way to remove password. If I dont get into BIOS then I just cant update it right? Do I need to get into it if I have full access to everything else on the laptop? I am the admin already. What about a fresh install of the OS? would that change anything? Thanks

    if you have password in bios the only way to unlock it is to upload main bios backup here

    Ok, so I will need to pull the chip in the bios and read it by eeprom reader and make backup to upload here?
