Update 11/6/19;  PC still going strong, removed the bottom cover and noticed the entire PC looked new, all parts looked new and professionally installed. FYI, this device comes with 4 slots for RAM, (2 under keyboard and 2 behind the bottom plate) After reviewing YouTube videos on disassembly to upgrade RAM, you would notice that there's more of an issue to replace RAM under the keyboard). KUDO's to this seller shipping this device with installed RAM under the keyboard leaving open and easy to install RAM under the bottom plate for the buyer and enabling future upgrades easier and less stressful. 2 years 3/6/2022 later have updated to W11 because it's compatible and everything from backlit keyboard, camera, microphone, wifi and everything else including all ports still working!!!!11/18/2023 decided against W11 so re-installed W10 and later PC became NON W11 compatible but no biggy!
