Hi ahamedashiq,
Welcome to the HP Support 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 that your Mini is not starting for you. You mentioned the wireless was flashing but what about the Num or Caps Lock keys? If they are flashing, how many times do they flash? When a notebook won't turn on there are only a couple of options we can try in the forums and removing the battery was one of them.
Thank you,
