Lithium Battery 3.7V 800MAH
· Remove 4 screws that hold board to cover
· Please note that upon removal of glued battery we discovered a third microchip – for a total of 3
· PROBLEM – even though all screws have been removed the board is still attached too cover; upon examination we discover a ribbon cable.
· SUCCESSFULLY Resolved – Ribbon cable removed
· Board now detached from back case, front cover

Results:
TEST WAS SUCCESSFUL REASSEBLED GAME WORKS AS WELL AS IT DID WHEN WE STARTED. Case reassembled and turned on again.
Discussion: With the proper tools and a little guidance we were able to successfully achieve our objective. I can see how for those who lack experience disassembling equipment like this how this serves as a confidence booster.
