Black screen while watching video

[YE58]

I've juste seted up my new HP laptop.  While watching video clip from youtube, and pushing the laptop's screen forward, it becomes dark. 

Any idea how can I fix it ?

Thanks

Hi, YE58;

There are a couple of possibilities here.

1) If the issue happens when moving the screen forward and backward, it could be caused by a loose video cable.

2) If the issue happens with the laptop display, but not an external monitor connected to your laptop, it could be the screen at issue.

3) If an external monitor also blanks out, it could be your graphics driver is crashing. If that's the case, you may want to update your PC using HP Support Assistant to ensure your BIOS and graphics drivers are up to date. You can also attempt to perform a hard reset by turning off your laptop, disconnecting everything from your laptop including docks, external monitors, power adapters, and anything else, and holding the power button for 30 seconds. Use a timer to ensure accurate timing. 

Let me know if you have follow-up information that can help determine possible causes.
