    1. Remove one screw on the bottom case, and then the optical drive can be removed. If you want to replace the hard drive, you should disassemble the whole laptop.

  1. It’s one of the crappiest assemblies I have ever seen.

    I tried to remove the small RAM cover, but I couldn’t do it. It was held in place by 2 screws. I unscrewed those, and then I tried to force the cover open using a plastic card, which is my usual method if I need a bit of leverage because it avoids damaging the plastic.

    No movement, NADA. The thing is stuck there. Is there anything keeping the cover in place except the 2 screws on it?

    I also tried the card on the panel edges, but nothing happened. Maybe I will try again.

    But god, such a complicated and crappy design.

  2. I wanted to replace the hard drive, but after successfully removing the keyboard, I am clueless about how to remove the palm rest/cover. “Pry open”? It seems impossible without breaking something.

    1. Among many websites, there is one that shows how to do it. I cannot remember which one it is.
      Start at the front and work to the sides. It’s a pity that I’m providing this information after two years. HP should be able to provide a sane website.
