BIOS update caused monitor to go black

HP 15-bs234wm
Microsoft Windows 10 (64-bit)

Hi there,

I was promoted to upgrade my BIOS by HP Assist. and everything seemed to have went well until after the hp logo screen. The screen was completely blank. I tried to search for the solution on my own  and tried resetting my laptop and restoring the BIOS to default, still have a black screen. I noticed that everything else seemed to be running so I decided to plug my laptop into my television via HDMI port and it seems that the laptop display is the only thing that isn't working properly. Any solutions or suggestions? I'm in the process of downloading my graphic driver again to see if that could fix the problem. Any help will be greatly appreciated. Thanks.

BIOS update caused monitor to go black

@Karakana Greetings from the HP Community!

when updates are interrupted or installed incorrectly is when such issues arise, nevertheless once the restore is done, the issue should be resolved, with that said, please ensure you follow all the below steps to resolve this issue completely:


Click here to perform a hard reset on your device

If the issue persists, after the above steps, try the below:

  1. Turn off the notebook.

  2. Plug the notebook into a power source using the power adapter.

  3. With the notebook off, press and hold the Windows logo key  and the B key at the same time.


    On some notebook models, it might be necessary to press and hold the Windows logo key  and the V key.

  4. While pressing those keys, press and hold the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows logo key  and the B or V key until the HP BIOS update screen displays or you hear a beeping sound (usually 8 beeps).

    The HP BIOS Update screen displays, and the BIOS update begins automatically. This might take several minutes, and you might hear additional beeping sounds.

    • If the HP BIOS Update screen does not display, repeat the previous steps. If the issue persists after repeating the steps, skip to the next step to Download a replacement BIOS file.

    • If the Power light turns off, the notebook has turned off because the Power button was held too long. Repeat the previous steps, making sure to hold the Power button for 2 to 3 seconds only.


(By the end of this article all the issues should be resolved)
