    Have you checked the magnet has not moved in the display housing?

    Yep, yesterday dismounted laptop screen bezel.Magnet on place and it unable to move( cant move it with screwdriver, magnet on place )
    1. Can it be that the magnet too weak?
    2. ALL SOFTWARE IS UP TO DATE, CLEAN WINDOWS ETC.
    3.This is floating bug, sometimes it appears, somtimes no.
    4. If screen don't start, i will wave with magnet over sensor area. And on 5th or 6th wave screen must start.
    5.This hint don't help if i will try close and open lid cover several times.

    Just disconnect the lid sensor, and see if your screen comes back.

    I don't think a lid sensor is essential to a gaming laptop like this, save for preventing the unit from turning on in one's bag.

    firstly, I don’t carry it in my bag, and the laptop is on the table, and I close it at night, but sometimes opening the lid does not light up the screen. Unplugging something on a new laptop is at least silly.

    Of you have a decent magnet you could use that to test the sensor.

    Is this with sleep disabled and testing just the sensor is the machine going to sleep and refusing to wake?

    Any hibernation or sleep mode are manually disabled.After this bug happens, I open the lid, the screen does not light up and the system works.if I connect the teamviewer I will control the system. When i press reboot, the screen will turn on after it reboots

    Any smaller magnet you can fit in and stick down would work.

    It's placed where it won't cause issues, anything (not silly super strong) will do.

    Basically without hard drives and given the placement of the magenet it's much of a muchness on the chance of causing issues.
