Lenovo Machine Type Model (Type 200)

Source: reverse engineered from the dumps of the data corpus.

Tells the brand of a consumer or small business laptop of Lenovo, e.g. an IdeaPad, a Yoga, a Legion, a V series one or a ThinkBook, IdeaPad for all of them, and its full machine type model, e.g. 20VE00U9RU, of which the system information (type 1) holds only the machine type, e.g. 20VE. The structures are 16 bytes long. ThinkPads carry structures of 7 bytes at the same type, which refer to three strings and whose meaning is not known, and which are left undecoded.
