hard reset is first which you hve done, next is...
Turn off the notebook.
Plug the notebook into a power source using the power adapter.
With the notebook off, press and hold the Windows logo key and the B key at the same time (WinKey +B).
NB: On some notebook models, it might be necessary to press and hold the Windows logo key and the V key (WinKey +V).
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).
