Actually Lenovo is the weird one here, all other vendors store the laptop model-name in PRODUCT_NAME rather then in PRODUCT_VERSION. For motherboards the motherboard modelnr is typically stored in BOARD_NAME and what is in PRODUCT_NAME varies. E.g. my MSI B550M PRO-VDH desktop motherboard has: DMI_BOARD_NAME "B550M PRO-VDH WIFI (MS-7C95)" DMI_PRODUCT_NAME "MS-7C95" So you may want to reword the commit message a bit.
