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.
