The other day, I put more ram into 2 12-inch ibooks - my own 1.0 ghz, and my wife's 1.33 ghz (Yes, I know she has the faster machine. It means I'm the next to upgrade). Anyway, this is the first time I had opened them up at all, and I saw something that confused me: I know that ibooks have only one available expansion slot for ram. That's what I saw on mine. But, on my wife's, it looked like there was a second slot lower down, just below where I installed the ram, but missing the clips to hold the ram in place. Is this in fact a second ram expansion slot, or is it just the shape of it that makes it appear to be one, or is it a second slot that is somehow unsupported or unable to be used? My guess is that it's just the shape of the hardware, and it only appears to be a second ram slot, but isn't really. But wouldn't it be sweet if there was in fact another usable slot in the ibook? Does anyone have any insight for me?
