I have an EliteBook x360 1030 G3 and after a motherboard replacement, I want to change the serial number and the FeatureByte. None of the known methods work. MPM is locked and cannot be unlocked via EFI.
Therefore, I read out the two chips and adjusted the serial number, FeatureByte, and Born Date using a hex editor. Now the system won't start anymore. I think I did something wrong with the FeatureByte, as there was a message indicating that the file size was changing.
My serial number is: 5CD849BL7Q
FeatureByte:3X476J6S6b7B7H7M7R7W7maBaEapaqauawbVbhcAd6dUdpdq... -
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... -

I have recently purchased a Lenovo ThinkBook Plus Gen4 Twist with Dual Screen. Here are the links for the product information:
ThinkBook Plus Gen 4 (13″ Intel) | 13.3″ & 12″ Dual-Screen 2-in-1 Business Laptop | Lenovo UK
However, somehow the serial number and the product name is no longer showing under the BIOS, Windows 11 or Lenovo Vantage.
Strangely the laptop's under cover does not show any information about the Make, Model, Type or Serial Number (No sign of tampering but no labels etc...). I am not sure what to do.
I do not have access to the original box...06-21-2025, 11:09 AM -
