Battery good, but will not charge.
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,
Ist dies eine gute Frage?
