Hi @Vane280,

 

Welcome to the HP Support Community.

 

I understand that you are facing issues with the black screen. I'd like to help!


I would like a few more details:


Are there any LED lights blinking?
Does the computer make any beeps or light blinks during startup?


Meanwhile, you reply that, 

 

Request you to follow the below troubleshooting steps 

 

Completely resetting the computer can resolve many issues that cause a blank screen. Follow these steps to perform a hard reset:

Turn off the computer.

Disconnect all peripheral devices and remove all USB devices and media cards.

Disconnect the AC power adapter.

Press and hold the power button for at least 15 seconds.

Reconnect the AC power adapter.

Turn on the computer.

If the blank screen issue is resolved, you are done.

If the screen is still blank, with no power or lights then it can be a hardware issue.

Hope this helps! Keep me posted.
