From the Club 100 support files (www.club100.org)... SPLITTING THE MODEL 100 CASE (The 102 and 200 split the same way) There is a trick to splitting the Model 100 case: The two halves of the case are held together by plastic notches in the middle of the edges. After removing the case screws you simply have to know where to push in on the case edges to split the case. Turn the Model 100 upside down, remove the screws at the four corners. Turn it right side up, like you are going to use it. Grab the left hand edge and rock it up onto its right hand edge. The bottom will be facing your left and the top to your right. Using your left hand, push down on the middle of the top edge of the bottom half and the same on the front edge facing you ... again, pushing in on the bottom half, only. With your right hand, pull the top half away from the bottom. The unit will split like a clam shell and lay open, easily. And don't pinch the keyboard wires putting the case back together. --
