I don't trust HP laptops for their chargers and batteries. We've had three different HP laptops over the past six years and each one has had problems with charging. The input for the chargers regularly came loose and meant the charger would not stay in at most angles.
They regularly had problems with the batteries failing to charge, and the more modern ones have had incredibly poor heat vents which fail to expel heat efficiently, and are very easy to burn yourself on.
I've not really looked at your laptop, and I hope it doesn't have problems and it suits you well, but personally I am put off of HP laptops after multiple bad experiences.
