Solved!

Updated bios but laptop won't boot. Keyboard and screen keep flickering then it turns off

HP Recommended
Hp omen 15-ax248tx
Microsoft Windows 10 (64-bit)

I got a bios update from support assistant which ran successfully to completion but the laptop has not been able to boot since then. Keyboard and screen keeps flickering on and off then the laptop automatically switches itself off and on again. Been like that for hours. Trying restoring previous bios but still no change. Can I get an earlier bios version for the omen 15-ax248tx?

@De_akatsuki Oh! that may need a BIOS recovery, a possible interruption, not deliberate, however, a power failure or a slight disconnection from the internet while downloading the BIOS update, could cause such issues, nevertheless, we have a few steps that should help resolve the issue, once and for all:

 

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.

       NOTE:

    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.
