    So a while back I posted this thread:

    Well now the problem arises again...only I noticed it is not charging at below I know it's normal that it doesn't have be be charged at 93% or so. But below 80% it should charge right? Crap. All it shows is the "green light" unless I'm wrong, someone please correct me. Perhaps I should just give it time and see it recharges back while I'm away? I've already drained the battery and recharged and it charge back like normal (if I had calibrated it right)... that was like a week ago I did that though. Should I be alarmed?

    Have you calibrated it following the guide?

    PowerBook G4 (15-inch Double-Layer SD), MacBook (all models), and MacBook Pro (all models)

    The battery calibration for the PowerBook G4 (15-inch Double-Layer SD) and any model of MacBook or MacBook Pro has been updated because of a new battery released with this computer. With these computers, follow these steps to calibrate your battery:

    Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
    Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
    Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.
    At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.
    Turn off the computer or allow it to sleep for five hours or more.
    Connect the power adapter and leave it connected until the battery is fully charged again.

    I woke up and it's still "not charging". Hm, I did do that a week ago...however is it important to let it sleep for 5 hours? I guess I shall retry and let it sleep more...if I can get it to fully recharge again. The thing is I haven't touched the computer at three days (maybe that's why the low charge?) when I woke it up it was at 82% and not charging...I thought it automatically recharges itself when it gets to a certain point. I unplugged the magsafe and let it drop to 79% and plugged it back in and it still sits. Perhaps I'm just getting worried for nothing...I don't know.
