I bought this keyboard off eBay broken just to tear it down for posterity. I found very little that could be repaired on it. But you get to see its guts. This teardown destroys the keyboard!

The plastic is very stiff and there are three sets of two hooks on each side. This one has been deformed on the back right hand side from a heat gun.
There is a 90 mm by 12 mm circuit board intersected by a vertical 53 mm by 7 mm board forming a T shape. The vertical board appears to be the bluetooth antenna.
Part # 820-2181 is printed on the board.
This board also has the Power Indicating LED light. This board fits inside the round casing unit by the power button. The power button, battery connector and keyboard all connect to this board.
The board is held in place with a small Phillips screw.
Ater removing the screw the board can be gently extricated from the tube.
Note the red and black wires. This connector inserts laterally. The wires go to the battery receptor in the middle of the tube.
The screw is in two parts, a phillips screw goes into a post screw. The top screw holds in the board and the post screw holds the On/Off switch in place.
