Hi all, I just got a refurb 12" 1.33GHz iBook about three days ago. I'm seeing some weird behavior when I plug it in for charging. It happened while I was calibrating the battery and again now with the battery at about 40%. When I first plug it in, the charging light glows green. When I close the lid, the charging light stays green. Also, the sleep light goes out completely. Every ten seconds or so, the sleep light turns on and cycles through one bright/dim cycle, the charging light flashes amber then green again, there is a clicking noise and the battery indicator light on the bottom of the ibook flashes. When I open the lid again, the screen goes on but it then goes out and into proper sleep mode with the sleep light working normally, and the charging light goes amber. I have to hit the enter key to wake it from sleep at this point. If I close the lid the cycle repeats. I did calibrate the battery and I tried resetting the PMU. Sleep works fine when it's not plugged in. Does anyone have any idea about this? Thanks!
