First of all: I have done all those PMU resetting stuff. The problem is that my iBook (1GHz, 768MB RAM, Tiger 10.4.3) keeps shutting off when I run it on battery. While plugged in there doesn't seem to be a problem. Here's what I've found out:
I've done all that PMU resetting, PRAM resetting, etc. Doesn't work. Any ideas as to what this could be? Bad battery? Any suggestions are most welcome
One more thing: I've run the hardware test, and it doesn't come up with anything at all.
Coconut Battery shows that my battery should hold a charge as well. Max charge is still at 3500mAh, 18 months and 750 cycles after I got the iBook.
- This seems to happen only when I run the iBook from the battery
- There is no pattern as to when it will happen: It might be fully charged, at 70%, 50%, etc.
- There are no warnings: The iBook just dies
- To restart it I have to plug in the charger, I can't start it from the battery after one of these sudden deaths
- If I press the battery indicator after a crash, it doesn't show any charge - no green lights
- When I restart the machine the battery indicator will work, and it show's a charge in Tiger as well
