Hi everyone,
I posted about this awhile back but didn't get any comments. My Pis has recently developed a charging problem -- will not charge either of two batteries. (I don't have a third spare battery to check it with, but it seems unlikely that both batteries went bad at the same time-- both had been fine.) The progress indicator shows that the battery is plugged in-- gives the "outlet" symbol but doesn't change to the "lightning bolt" symbol. I tried all the usual voodoo -- PMU reset, PRAM zap, NVRAM reset, programmer's reset -- all to no avail.
So I figured it had to be a hardware problem. I bought and replaced the power/PMU board, assuming that that's what it was likely to be. In replacing the board, I did see that there was some corrosion around some of the contacts which go to one of the batteries. "Aha!" I thought... that's what it had to be.
However, after replacing the board, I still can't charge a battery. Anyone know what else, if anything, there is to try? I'm beginning to wonder if it isn't possible I have two bad batteries that happened to go bad at exactly the same time (as unlikely as that seems) or that there is some sort of software, rather than hardware, problem...
