Thank you for your helpbut I don't think it's your file which got problem because I have realised that when I power on the laptop there is no display and after a while it will start blinking 6 white and 3 amber blinks to show bios problem and then start the screen test sequence. So after I tried your patched file I also changed the bios and it did the same and then I put back the original file and still it's doing the same. I have checked if maybe I knocked some resistor and soldering but all looks fine. So I was thinking if you could help make a clean bios file from my bios file and try again. Thanks

I am trying clean me file but it's still doing what I mensioned above, so I believe I might need to reconstruct the bios from exe file but I am unable to do it so I need help to do that from good people of this forum.The laptop is Dell Latitude 3520 Service Tag 1P2YGL3, mainboard 213047-1 Cyborg L15 MB TGL.

Thank you Rex but it's not displaying no fan spin, when I put charger the laptop comes on and after some seconds it goes off if you try to press the power button it does not respond but when I remove charger and put back it does the same again, no display no backlight
