Contrary to HP technology, you can add 8 GB on a HP 15f-039wm with a screen size of 15.6 inches and no touch window. The problem is that the screws above the memory module contact screws with clips C" They just loosen and then hold. To remove the cover you have to use something like a very thin knife blade on the corners and pry open the cover, while placing other items to hold the side open.The cover has tabs so you have to go around the square and pry open each side, long side and short side.Just be careful not to break the cover as it is plastic Removing the rest is fairly easy Replace the 4GB memory module with the 8GB memory module from Kingston Identify the 8GB Kingston - KVR16LS11/8 and the GB PC3L 12800 CL11 204-pin SODIMM module, insert and close, but don't forget to remove the C-rings on the two screw tach to make it easier to remove the nest if it's an i got Malchine downloaded and it registered 8 gigs and that's it. Overall very good deal, knowledgeable seller, fast safe delivery. I will refer to them again for my memory needs.
