Hi I was hoping someone would help me with this. I just rebuilt my Ibook clamshell battery and it works in open firmware perfectly fine, I am reading 14ish Volts across the the whole battery (each cell is 3.5ish). However the second I unplug the battery while in OSX it dies immediately. I have tested continuity with my solder joints my spot wells are iffy but they seem to work as i am reading 14V. Any help or insight is greatly appreciated.
