Thank you for confirming NVME support by the 2nd m.2 slot. I also eventually switched to mismatched RAM but in 16+4 configuration and I also observe no issues or performance degradation in games and other software

I have an update. I got my hands on a 16 Gb RAM stick. Installed it in my laptop, so I got 4+16 configuration. Everything works fine. No drops in performance can be observed in daily usage. I was mostly concerned about gaming performance but fps remained the same. I have played Overwatch to test gaming. So it is a solution for this line of laptops. Not ideal but still good.

Thanks Shacruel, I didn't know about that site. It's truly a jungle of different specced laptops out there from all manufacturers. I have spent so much time researching this laptop purchase and still I wasn't sure about all specs. Makes me think about how many customers gets tricked into paying to much for outdated or underspecced computers.

https://psref.lenovo.com/ This site actually has a lot more information about specs of their products than their regular consumer site.

Thank you very much for the review. I have ordered copper colored R5 3500U unit today.
