@LAPTOPADDICTNZ HP has a few parts tested and approved to work on the device, and lucky for you, the model you've selected has upgradeable options, here's what you need to know:

You may order the replacement parts on the HP Parts Store, however,if you couldn't find it on the HP Parts Store, you may want to get it locally at the online store such as Amazon or eBay, etc...as the part numbers are universal.
