Do not damage the ribbon tab (pictured). It is vital to the device.

Push the ribbon tab (sticking out below the main screen) backward through the square hole to remove the main board of the device.

Once the wiring is removed from the front panel, release the hinge at the bottom of the device. To do so, gently pry underneath the clip (pictured) with a plastic opening tool. The clip will pop up, and the motherboard can be completely removed.
