Strange behavior of brand new Yoga C930 screen

2019-03-15, 2:32 AM

Hi, tried out a brand new Yoga C930 with 4K screen the first time yesterday. I came across three issues:

 

1. When I took it out from a computer bag, I flipped it to tablet mode. Wallpaper showed up but the Windows login prompt did not. I had to flip the LCD to turn the laptop into laptop mode. Then, the login prompt showd up. What is wrong?

 

2. After I logged on, some area of the screen were not responsible. For example, I touched the Windows icon at the bottom left but nothing happened. Similary, the computer did not respond when I touched the middle of "Type here to search". Is the touch screen defective?

 

3. I connected the laptop to a projector at school, even I chose mirror mode, nothing happened on the projector. I went to a different room hours later. Again, connected to the projector via Anker's usb-c to HDMI adapter. It did not work but after a while, my laptop screen showed up on the projected screen.

 

Is my new laptop defective?
