    I've got a 2010 MacBook Pro, (13" 2.4 Ghz C2D), running Snow Leopard, and I just noticed that when taking unplugging it and using it around the house, the battery manubar doesn't change. It still shows it as being plugged in, and when I click on it, it says: "Battery if Charged; Battery Source: Power Adapter"

    This is very strange, since I've now been using it for over four hours unplugged... I'd love to think that Apple figured out a miniature perpetual motion generator for its laptops, but somehow I think that's not the case. Any ideas?

    Restart your Mac.

    Then reset the SMC and PRAM/NVRAM:
