I ran into a problem: after 2 hours of inactivity, the laptop screen turns off (or goes into sleep mode, or only the monitor turns off — I can not understand), does not respond to keystrokes. There is a completely black screen with nothing (no “stick” or console, terminal). But the laptop keyboard (power-button and num lock) are highlighted.
This happens with a period of 2-3 days. Sometimes the laptop goes into sleep mode and everything is fine, sometimes - trouble. I also have the second OS, if this is important, - Windows 10.
