Chosen Solution
I have two of these laptops, one is used simply to charge the battery but doesn’t work otherwise, and the other is fully functional, save it will not charge the battery. When plugged in the battery does not deplete, but simply won’t charge. Doing some research I have reset the PMU and checked the PRAM to see if that battery was dead, but it appears to be fine according to the guide on the mac website. It appears also that the PMU which I am guessing is responsible for charging (?) is part of the motherboard and not substitutable from one machine to the other. I know very little about computers however, and I wonder if anyone with a more comprehensive understanding of how these machines work might offer any help or opinion as to whether this problem is feasibly operable or whether I should just continue as I have been and be glad that I have another PB to use as a charging unit - allowing me a semi-portable machine. Thanks in advance, Martin
Could be your charger, or DC-in board. System Profiler->Power will tell you if the computer detects the charger, and if it’s charging the battery. It will also give you the battery status (number of cycles and if it’s circuitry is reporting problems). If this Answer is helpful please remember to return and mark it Accepted.
Try downloading and running Coconut battery and let us know your results. You stated “When plugged in the battery does not deplete, but simply won’t charge.” Do you mean the machine will not even draw power from the battery? http://www.coconut-flavour.com/
My battery is 0 percent .its not charging. Battery condition is showing good. Mac laptop goes off when unplugged.
