Had to replace it a few times now. First one the hdmi out would glitch when you closed the lid and the keyboard backlight stopped working after a month. Replacement was stolen from my front door(nobody's fault but lesson learned and I'll use Amazon lockers for expense electronics moving forward), third keyboard backlight didn't work. Hopefully the fourth will just work. Good return policy via Amazon, be sure it fully works before the return window expires. When I called Dell they said it was out of warranty on their side.UPDATE: Fourth computer the left click mouse doesn't work out of the box, returning for a now fifth time..... Hopefully number six will be a winner. I'm really getting tired of getting laptop after laptop that doesn't just work....Update 2: computer overall work's fine. The backlit keyboard went out again after getting the 5th computer I got but since I've had so many issues with all the other ones I received I'm not willing to send it back only to receive another module with different problems that are worse.....
