IMO, This Envy 17 was the best build quality of them all and since then I guess they did move into making it into the dv7 family, when I saw the launch and release of the Omen family I knew that was EOL for quality Envy's. I followed the manual and took the laptop down to the cpu fan I completely forgot to take pics or make a video until the end but here are two mid way in closure. I have been looking at the new service and repair manuals from the new ones and to the best of my knowledge all you have is space for one sata hdd and one msata or m2m slot for a ssd chip. Find service manual and scroll through it. What are the exact model number and product of that line. From the cpu you have me when i look it up on cpu-info's website it tells me those new ones are soldered onto the board... HP and me have a funny relationship I call and know more about my laptop than the reps and sometimes they take offense to it and try to screw me. Anyway the features on this laptop now are long gone but the new chips 5th gen i7- and Nvidia cards are better at heat and energy consumption and the graphics have way more memory. I feel in love with this beats audio spin wheel and really good sound from this series. People to this day are blown away from the speakers. I will research the new ones and see what laptops will be out in 4 months when my care pack ends.
