I’m not sure if anyone else has raised this with you but Lenovo choose to store their machine model number in a different WMI location to that of Dell and other OEMs. Because of this when you look at Console Tools -> System Information on a Lenovo machine you see a meaningless (to us at least!) string. Would you be able to introduce some logic into your application that first checks if it is a Lenovo machine and if so checks Win32_ComputerSystemProduct instead of the usual Win32_ComputerSystem. That would be extremely handy.
