I got this laptop about 2 months ago. It has been working flawlessly so far.
I was using it yesterday without problems and I was also using it for music earlier then suddenly the laptop started repeatedly restarting while it was around 10% power and I turned it off.
A little later, I turned on the laptop and the Windows 10 login screen was only displayed in red, green and blue. It was alternating between the normals colors and RGB.
I decided to connect it to my TV with HDMI, to identify the problem. I discovered that the flickering stopped as soon as I plugged in the HDMI cable (the TV still being turned off)
I was already wondering if one of the graphics cards were already broken and if I have warranty.
I tried going to device manager and found an update for the Intel integrated card and installed it. Afterwards, I unplugged the HDMI cable and the flickering had stopped.

When I started writing, I had not found the current solution yet.
Do you think I've solved the problem or will it come back again later? Should I call in and ask for a new model?

I am kind of worried, as I took a while to save up the money for this laptop. I am taking good care of it and expect it to at least last a couple of years.
