    Guys, i think the battery of my macbook 5.1 unibody is giving some problem.

    Few months back, when i wanted to use the macbook without the magsafe, the battery status shows 99% at the time when i disconnected it from the power point and apparently, i just use it for like 20 minutes or so and it just shut down by itself for no reason. I wasn't unable to power it on immediately but was able to do so after i reconnect it back to the power point with magsafe on and it shows me 78% batt life...

    Initially i was thinking if it was just one off incident, but no, my subsequent attempt to use it without magsafe resulted in the same shut down to occur.

    Just now, i've encounter it yet again, so before i posted, i have already read through all available forums, performed battery calibration, resetting the SMC and etc.

    I followed the instruction here, and the battery condition show "CHECK BATTERY" via system profiler

    Anyway some info of my macbook:

    On the fence
    You do need a new battery, however, since you are under 80% capacity and under 300 cycles, apple will replace it for free for you.

    is it applicable to all apple store worldwide? im residing in Asia, specifically Singapore. I did ask on some local forum, and most answer was, since you;re out of warranty, you're out of luck...

    If you're out of warranty and don't have AppleCare, Apple isn't obligated to replace your battery. However, many Apple reps have been known to make exceptions to keep customers happy. It doesn't hurt to ask.

    This should answer most, if not all, of your battery questions:
