Immediately a week after the warranty expired the HDMI port was no longer working properly. The display will flicker constantly with a lot of artifacts and it is basically unusable. At first I thought it might've been caused by something else but changing to a different adapter fixes the problem.

Product arrived with the Ethernet port not functioning. Cable plugs in and lights up, but laptop cannot see Ethernet. Contacted support, and they wouldn't assist. Also, product does not include charging adapter as the title suggests. Product page needs to be clearer about what is included in the box.
