Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I see you are having an issue getting your Pavilion to boot up. When you try does the Num or Caps Lock key flash? If so how many times? You can try doing a Hard Reset to see if that helps.
Thank you,
