so when i ran a scan on dell support assistant when it was scanning for new driver versions it showed an optional bios driver update so i clicked install and a few seconds in a weird slow drill sound played inside the laptop it sounded like a motor or something which for some reason made me turn the laptop off (i hope it hasn't corrupted the bios now) because of the sound, is it normal? why does it make that sound when i do that
