Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community! I came across your post and wanted to assist you. I understand you are having issues booting your  HP Notebook - 15s-Fq0012na. Don't worry we'll work together to find a solution for you.


To provide you with an accurate solution, I'll need a few more details:

Have you recently made any software or hardware changes on the PC before the issue started?

Did this happen after a power surge or power outage?


In the meantime, let's try these steps here:


Perform a Hard reset on the PC: 

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

  1. Turn off the computer.

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

  3. Disconnect the AC power adapter.

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

  5. Reconnect the AC power adapter.

  6. Turn on the computer.

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

    If the screen is still blank, continue with the next step to listen for computer beeps and look at the lights.

Attempt a BIOS recovery >  HP Notebook - 15s-Fq0012na


If the above steps work and the display turns on: Perform a hardware test to be on a safer side.
