I would like to buy a laptop, but with a few conditions:
The screen should be large, display should have good black level, it should have a large battery and a reasonably good design of a good company.
And it should not go over 1350 and I do not want a computer, because then I prefer to ask my dad
In advance: I do not want a Toshiba
Just look at Notebooksbilliger, there are 100 that meet your needs.
If you want to gamble but please take a PC and no laptop. Did not name what you want to do with it.
Buy a used laptop. They are usually much cheaper, but still offer a great performance. For example, I have seen many used for about 800 euro with i7 8700K and GTX 1060. You will not get such a P / L anywhere else.
