My TiBook is running at 667MHz instead of 1GHz because it has no battery installed. I'm capable of building a battery from individual cells but don't have the dead battery anymore, so don't know the pinout and don't have the pcb. An iBook battery pack that I have is 3s2p, the TiBook needs to be 4s2p so I don't expect I could use its pcb. Does anybody have the battery connection details, full schematic, or any info on how to activate the "battery present and correct" circuitry? I like the TiBook, running openBSD ok, but crippled by the lack of a battery and I don't really want to throw money at it.
