I need a laptop that works fine. It shouldn't be small, so from a 13 inch diagonal it would be good. Does somebody has any idea
15 inches with sufficient battery - take the cheapest one - is enough.
Such small laptops are quite expensive if they are still reasonably powerful like this one:

I would take an honor Magic Book 14 even if it is a bit too big
I would buy a lease return. Mostly good devices that work for school and study. Just google "refurbished". I've only had good experiences with it.
