Hello Serg008! On the advice of "zhenyashot" I decided to contact you. I have a Lenovo B570e and after what firmware BIOS mods the serial has changed, I find it difficult to say. Please help me fix the serial. Here are the files used by "drive.google.com/drive/folders/1b21qXig7pnGTnQgyA4lflES74NHkgdyY?usp=sharing". There is a file there. My serial in the photo. Thank you very much in advance! All three files are interesting.
