How to check a laptop for a used return in dns?

Question

Windows

I want to buy a beech in dns
How to check that it is not a return and used?

Answer 1

Don't give a damn? Well, they will give a guarantee
And so - only factory sealed packaging

Answer 2

Previously, they looked at the presence of seals and traces of opening, and of course the packaging. If the box is taped with a DNS label, then this also says something (unless it is DNS). Also, if without an OS, then, naturally, no axis should be on it. Pay attention to the presence of fingerprints on the surface.

Answer 3

Lord, what questions.
You look at the outside.
You look at the disposal of the battery
in programs like AIDA, there is information about the date of the last installation of WIN.
