Hoping the likes of Bunnspecial, Hrududu or anyone else familar with complete strip of the G4 Cube can assist me here. I'm currently disassembling a G4 Cube and am trying to remove the logic board. For ref as a guide I'm using the Apple Service Source doc dated 2002 - found after internet search. Ref pages 65 thro 72. Have removed all the obvious screws detailed P65-67, and yet to prise up between the heat spreader & heatsink, so not suprisingly the board doesn't yet budge. What's puzzling me is, there is no mention of removing the 2 corner pillar bolts (shown below) which surely is a requisite before the board can be removed. Or am I missing something all to obvious? I'm no newcomer to messing with Cubes, having changed optical drives, HD's etc, but never dug as deep as the logic board, which I wish to remove, inspect, & repaste the processor. I find it hard to believe that Apple would have overlooked a disassembly step in their procedure, or is it me simply not seeing the wood for the trees? Also an aside, I suspect I may have a problem with the DC to DC board. Is this known to be a common cause of failure on the Cube?
