Both type-C ports stopped working with video after 11 months. A 2nd monitor connected to a type-C/thunderbolt port showed "no signal" error on screen. Port provided power, but not video signal.
I returner laptop to seller for repair. They returned it to me with a video of them testing it (showing it working). However, the C ports still did not work for me, even with 4 different new thunderbolt 3 cables. Seller said no to my second request for repair.
