On my screen appeared a thin black horizontal line (near the top of laptop screen). As I can see, it's not even one pixel wide and not noticeable at some angles. It's not software problem because I see it in both windows and linux as well as boot manager. What can it be, and can it be fixed?

Hello @alexanderche
Sorry to hear that you are having problems ... I would like to help you.
(1) Double check with external monitor connected via vga/hdmi cable.
Do you have the same error pattern on external monitor ?
- Power off external monitor
- Connect vga/hdmi cable
- Power on external monitor
- Power on notebook
(2) Please report your results

Well, I can't really test this cause I don't have any external monitor, but I'm quite sure that this is the laptop's monitor problem cause it is reproduced in windows/linux/bios/boot manager. I'll try to find a monitor to test and give further info later.
