On the plus side, they got it to me very fast. While it mostly works, the HDMI port does not. Also, sleep mode seems to not be fully supported in hardware. The price was high given this. I needed a working laptop for work, so I decided to keep it out of desperation.I already owned a 4K version of this laptop. The motherboard recently died, and Dell no longer supports the unit. I bought this refurbished, HD version of the laptop from this vendor so I would have two nearly identical units. This will ultimately enable me to have one working and one for parts in future. Once the warranty expires, I will probably try to take the 4K screen/GPU out of old laptop and put into this one.
