Thank you very much, SMDFlea , for your help.
I read the topic more than once, and after several attempts, I was able to repair the BIOS file and remove the endpoint message.
However, another message appeared ( Manufacture Programming Mode in Unlock mode).
I used a program (BCU BIOS Configuration Utility)and made a copy of the file(config) from another laptop of the same model, and it worked fine.
But the question here is:
The device data label was previously removed.
So how can I obtain laptop data, such as the serial number, model, etc.?
