While Still on the back, look for a plastic cover that says "HP 3D DriveGuard." (AKA. the longest cover)

Unscrew it, there are 3 Philips screws on it.

Personally, I do not have a drive in it right now, but you will need a 1.8-inch drive to fit it into the laptop. Plug the SATA Drive into the connector.

For the ram pull the two gray things a bit and then take out or put in the ram at an angle.
