Launcher Stopping PC from "Lights-Off" Mode

I know that is not an urgent matter but I taught why not ?

I usually start my updates/ downloads at night and leave it open before I go to sleep. So that they can get downloaded next morning. Slow internet speed.

I noticed that when launcher is open it disables my laptop’s " Lights Off" mode ( you know activated with Function key + F6 where screen turned off and all the lighting of keyboard is disabled ? )

I just activate it and after 40 seconds it gets turned on as if I moved the mouse or pressed a key.

It would be great if that it wouldn’t cause so. I know it is not urgent but it might be something really simple.

Thanks in advance.
