At least this part is easy. Simply push both tabs outwards, away from the center of the laptop, let go, and push/pull the battery out.

Annoyingly, in many newer laptops, screws are hidden under the rubber feet. This is one of them. Only the circled rubber feet have screws under them, the fourth one does not. Pry them off.

Remove the single screw from the memory door, and pry the door up.

Remove the single screw under the memory door.

With the laptop's battery area facing away from you, pull the bottom cover towards you. It will slide towards you.

Pull upwards on the caddy's tab.

Pull the connector away from the caddy, and set the hard drive aside.

Use a guitar pick to separate the base from the palmrest.

Remove the four heatsink screws surrounding the CPU socket. This is necessary as the heatsink blocks the hinges from being removed.

Remove all of the shown connectors. Remove the motherboard screw hidden by the video cable. You'll have to break out the Philips #0 bit for this, if you haven't already.
