Questions about ASUS ZenBook 15 UX533FD-A8079T

According to my informations, it uses one of those square shaped adapters, like this one: ASUS AC Adapter (90W) Dimensions: 89 x 89 x 32 mm I don't know the exact weight. But it should be closer to 200g than 500g.

The official warranty still applies but this is a product that has at least been opened and perhaps displayed in a showroom. So it is already used. After that it is still a "new" product.

Screen top so far. It was probably a serial error...
