Answer 2

It's a delusion. Russian law does not allow conditions under which you can lose the warranty.
How, excuse me, will you clean your laptop without opening it? And the procedure is mandatory, otherwise, if the cooling system is clogged, you will overheat.

Answer 3

I have never seen factory seals on laptops. Most likely - the seal of the seller.
The usual practice is to go with the laptop to the seller and ask for more memory. He will sell you the memory, install, check and take care of the compatibility of the memory and the preservation of the warranty.
