I listed all the details about this laptop in the pictures I provided above. I bought it in late September last year and used it for like three months, then a problem errored, more especially the laptop will go black screen whenever I start it. And ONLY the screen will be black, everything else on this laptop is working completely fine. The keyboard will growl when you use it and sound perfect. The guy who tried to help me repair it said it was because the wires that connect to my screen and CPU were not done right at the beginning, therefore damaging my D drive after several times Forced shutdown. Fortunately, Lenovo has finished the repair for me and now it's working perfectly fine. I have deleted everything I downloaded on this laptop, but I suggest you do another deep cleaning just in case. All in all, it is a great gaming laptop.
