                              Hello. I have a very strange problem with the bios file. After deleting it and trying to enter the same file again, the laptop does not start and remains at 5v. I tried with another bios chip XMC from another laptop and I get 19v but now the display changes colors. then I tried to read the same XMc chip to erase and load the same file, but now with the same file I get 5v. please help
