Hey everyone... like so many of you, I too have been having the 'typical' battery problem that so many have reported with iBooks. if you can view the image I've attempted to attach, you'll see my xbattery curve. Click Here The first problem was it wouldn't charge at all, so I performed the open firmware (Cmd-Opt-o-f) commands reset-nvram and reset-all, and that got me charging again. it was after this that I began running the xbattery app. So, as you can see, it would charge from 0% to around 25%, then immediately jump to 100%, as many are experiencing. Discharging, the reverse, from 100% to around 75% in an hour or so, then jumping to sleep and 0%. multiple cycles seemed to make the problem worse, rather than better, when I wondered..."what if the battery isn't actually dead, the iBook just thinks it is, and chooses to go to sleep because of it?" so, with the power plugged in for a few seconds, I revived osx, and immediately unplugged it again (with the battery still at 0%). as long as i kept the mouse moving around the screen constantly, it stays awake for a while longer. if you stop the mouse movement, or try to open an app, it goes back to sleep. after repeating this again and again, it became apparent that there was still a significant charge left in the battery, even though it reported 0%. Next step, I removed the battery, and connected to an ohmmeter to test voltage. I was still reading 11+ volts DC from the battery, so I found a halogen licht bulb, and quick-and-dirty wired it to the left-most and right-most connectors on the battery. I have no idea which of the 6 connectors on the battery were which, so I just guessed and tried 2...it's from these I was reading the 11+ VDC. so, I connected up the halogen, and it lighted. I know this is a fairly high-drain bulb, but I have no idea what the specs are, but I connected it, and it's still lit after 2+ hours now. I'm wondering...if there's this much charge still left in the battery, will depleting it completely, as evidenced by the bulb eventually going out, allow me to charge "completely" from "true 0%"? We shall see. It is my hope that unlike resetting the nvram, pram, or else which has seemed to have little effect, that this may do something? it can't get much worse than where I was before I started all of this, so we'll see. Any thoughts?
