Hi,

Follow these steps to recover an earlier version of the BIOS on your notebook:

1. Turn off the computer.
2. Plug the notebook into a power source using the power adapter.
3. With the computer off, press and hold the Windows logo key and the B key at the same time.

    note:

   On newer notebook models, it might be necessary to press and hold the Windows logo key and the V key instead of the B key.

4. Still pressing those keys, press and hold down the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows and B (or V) keys until the BIOS update screen is displayed or until you hear a beeping sound (usually 8 beeps).
   The power LED light remains illuminated and the screen remains blank for about 40 seconds before anything appears on the display. You might also hear beeping sounds. Eventually, an HP BIOS Update screen displays and the BIOS update begins automatically.
