Remove the back panel carefully.

To remove the back cover, there are 5 plastic snap hooks that must be dislodged with a spudger or plastic pick tool.

Lay the device upside down with hinges away from you. Tilt it at 45 degree angle, leaving hinges down and open the screen slightly. Apply a little pressure on one corner to see where it separates. Then work from side to side to separate the back case from the top case. The back case is a shell with no components in it.
