Hi i have a dell inspiron 5559, my laptop was working fine until i took the cmos battery and replaced it again. I had an issue with my AC charger being unrecognized so i wanted to turn off the warning, but i had an administrator password set, which i dont know, that’s why i decided to reset the cmos to remove the password.
But know when i try to turn on the laptop nothing starts at all except the fans keep running very fast, completely black screen (dosen’t turn on), no keyboard lights, and the Battery indicator goes white and orange. Could this be that the bios is corrupted even though i reset it, or the whole motherboard is dead? If it’s bios failure how can i reinstall it? please help, i need an advice.
