Lenovo V15 i3-1005G1/8GB/256/Win10 screen wakes up on its own


Mar 16, 2017
Hello. My laptop is

Lenovo V15 i3-1005G1/8GB/256/Win10.

I have installed Windows 10. Also power settings: Screen goes to sleep after 10 minutes of inactivity. And yes its working.
Yesterday after 10 minutes screen goes off, i dont touch mouse anything. And in some moment he wakes up on its own,itself. Why? Maybe it was mouse itself or it happens? Thanks

On background i had Google Chrome opened with 2 sites only.

ps:For 99% it was laptop. I have paranoid about my main pc that maybe it was screen from my main pc.
