Rotate the device 180 degrees so that the bottom of the device is facing you.

A ribbon connects the battery on the rear cover, to the motherboard. Slowly lift the bottom of the rear cover up until you can see the ribbon.

Use a spudger to push the ribbon away from the motherboard and parallel to the motherboard in order to remove the ribbon.

Separate the rear cover by lifting it up away from the main system.

When reassembling the rear cover to the motherboard, reinserting the ribbon cable with a spudger may prove difficult. In this case, gently use your hands to slide the cable end into the slot until they click into place.
