It can be a hard task, I work for HP and do a few of them each week. The best advice i can give you is to be very careful of the plastics and the ribbon cables. Also it may be worth it for you to pick up a small plastic organizer and label it so you do not loose track of the screws. If you get me the product number, i may be able to get you a copy of the HP install manual that will guide you through the process. If you need anything else let me know.
