Before we go any further, it is important that you know that Intel does not support integration which is when the original wireless adapter is replaced by another one. Please check this link for further information on this matter: Regulatory Information Regarding Hardware Installation or Upgrade
With that being said, our first recommendation in this particular situation is to contact HP* in order to find out if they have any drivers specifically designed for this adapter. You must consider that this adapter may not be fully compatible with your system and only HP* can tell you which adapter is right for your system.
