I will be more than glad to assist you with your matter.
Before I can provide you further assistance, I would like to recommend you to install at first the manufacturer (OEM, HP in your case).
This is due to your manufacturer, provides you with the original drivers that are tested to be compatible with all the components of your laptop, Our generic (Intel) drivers, will work well too, but they may not include some features provided by HP.
