Good morning, gentlemen, I hope you can help me with my laptop, I told you that I saved it about 2 years ago because it wouldn't turn on, now I have a ch341a programmer, I made a backup of the bios, I flashed an original downloaded from lenovo and it started, but it turned off after a few minutes, I entered the bios configuration and the brand, model, serial number, windows serial number, etc. did not appear, I request your help, I did everything I found in the forum but I could not solve it, also now it won't start again, it turns on but the fan does not turn, I will share all the information...
