It only manages expansion cards we don't have backups and doesn't need to program it, laptop right now or not?

This laptop entered without turning on due to bad update of bios , erased that u12 by mistake and programmed the new winbond128 the equipment turns on the fan and turns off and continues like this all the time without image

Hi How are you, When I flashed the BIOS with Clear Me.Bin on the 480s 20L8 Models the fans started going on again but still no POST, Will turn off but it is at least showing some signs of life. Any Ideas? Do you need the motherboard serial # ? Please let me know thank you so much!
