Where can I find a 15.6" laptop without accounting buttons?

Question

laptops

Hello!
I have been sitting on the samsung r560 for almost 10 years. Has undergone many changes. Of course, the fire works like a fire in its old age, but it began to lose ground, it began to warm up. There was an idea to make a cooling pad, but you will have to carry it with you.
I'm looking for a 15.6" laptop without accounting buttons, light, powerful, easily upgraded. I look around the Russian Federation, but I can't find these two conditions that are important for me together ( 15.6" without accounting buttons ).
I understand, of course, the main thing is the filling, but it’s important for me to transfer the convenience of typing from an old laptop to a new one.
Thanks in advance for your reply.)
