I have a T490 TYPE : 20N3 device. There is a problem with the fan working quickly, but there is nothing on the screen. The laptop does not work. Is there any help in cleaning my bios? Thank you.

Strange is that light current consumption 25ma and fan spinning occur with original bios only, all other bios from internet and self-compiled following not more than 4ma current consumption and fan without spin.

What does a spinning fan do, it doesn't help you get a picture.
