iBook won't power on after attempted PMU reset
Hi there. I recently purchased a used iBook G3 (700mhz/20gb HD). It was working fine for a week, and then all of a sudden, it died and no longer wants to power on.
This is the sequence of events.
It was having some battery issues -- the battery would show 30% or better charge, but it would go to sleep, as though it had no charge. Upon plugging it into the AC cord, it would then show 0% charge (until it fully charged, of course)
I attempted to reset the PMU by powering off, disconnecting AC, and pressing the CTRL-OPTION-SHIFT-PWR combination. Nothing happened, that is, no tone, or change in light on the power cord.
From that point, the iBook would no longer power on at all. I tried with both the battery in, the AC cord connected with the battery, and the AC cord alone with no battery, and still no luck.
I tried attempting to reset the PMU again, with the aforementioned multiple formations.
I don't think it's the DC board, as the power cord continues to shine green whenever it's plugged in.
I don't think it's the battery, in spite of the battery charge level issues, it still shows a full charge when pressing the level button. Also, it still won't power up even with the battery removed and only the AC cord connected.
I'm not sure, but I don't think it's the logic board, as it didn't exhibit the flickering screen issue associated with the logic board.
The RAM and Airport card are seated properly, and I tried powering on with them both removed, and still no luck.
It was running Tiger 10.4.11
Any idea what happened here?
