    I picked up a black MacBook on eBay recently and it seems it came with a new battery. The battery is not an Apple one and oddly the exposed surface of it is more rubbery than the rest of the MacBook. I didn't expect much and my initial impression was that it lasted a pretty good while, but seemed to discharge while sleeping a little faster than expected.

    Anyway, the problem has become that while it's plugged in the menubar battery info flashes (Not Charging) every once and awhile as if it loses its connection. At first this was infrequent and didn't seem to matter. Now it happens every 7 or 8 seconds and leads to the battery charging fantastically slow. It's at 72% and iStat says it needs another 23 hours to be fully charged (it said 10 hours about 15 minutes ago).

    Any idea what's going on or how to fix it?

    Hmm, it may have been mostly outlet related. I just switched it to the other socket on the same outlet and now I'm up to 75% and it says 1 hour 50 minutes remaining. That still seems like a lot, but at least it's not 23 hours. Was the other plug likely just giving me a sloppy supply?

    No idea why it's doing that... Maybe the charger port is dirty. Try cleaning it with rubbing alcohol. Also, that's what you get for buying off of eBay... You should always ask EVERYTHING before buying from there.

    Oh, sorry, I was typing when you posted in my before post.. Anyways, that could be it, most likely. Or, if it happens in more outlets, it might be a defect in your charger.
