I think I got all the main specs in the title. It is currently running Windows 10. For IO it has 3x USB 3.0 type A, 1x Thunderbolt 3, 1x HDMI, 1x Mini DP, Ethernet, SD card slot and headset jacks. Keyboard is backlit and has 4 customizable lighting zones and feels amazing. This is a very good laptop. It is easily upgradeable and I have even added an extra 16GB of RAM from the base model and the storage is easily accessible as well to upgrade if needed. It is a very fast computer and easily keeps up in all modern games that I have played. I used it for my computer science degree and had no problems with working on it as well so it makes a great work/play combo. Only issue I have noticed is it gets pretty hot when gaming. I am including my laptop cooler that I used for this reason at no extra charge since I no longer will have a use for it. I am also including the travel bag I used as well for the same reason. Feel free to reach out if you have any other questions about it. I have kept very good care of this machine treating it like my baby. You'll be hard pressed to find any markings of wear and tear and certainly none affecting the machine's use. I think you'll be very satisfied with this laptop.
