Tried win+shift+ctrl+b, pushing power buttom for 30+ seconds and reconnecting the charge line etc.
It’s weird cuz it doesn’t seem like monitor is completely dead. It just briefly appears and then 0.5sec later, turns to black.
I contacted customer service but god they are slow responding. Got ghosted two times…
When it turns black, is the computer still running? like fans and lights. In that case try connecting it to an external monitor. But first, you can try pressing the windows key, control. shift, and B keys all at the same time, this might reset the monitor connection
When you want to try connecting to an external monitor plug monitor in start computer keep pressing the Fn key and either f5 or f8, cant remember which key it was until you get a display on the external monitor
If you cant get a display on external monitor either its likely a more serious issue. You can unplug it, take it apart, and pull cmos battery for a minute and put it back in. Beyond that, I have no suggestions besides taking it in
