If I tell any motorcar's Main dealer the VIN number of my car, they can almost immediately tell where it was built, the exact model, what engine & transmission it has & many other details. When I tell a computer manufacturer such as Acer my Laptop's Model & Serial No. they don't appear to know very much e.g. they offer me several graphics drivers, several sound drivers, further choices of camera drivers etc. etc. all supposedly for the same Operating System. If the manufacturer of the laptop cannot be more specific, then how is the innocent owner supposed to decide which drivers to download & use?
