    Hi guys,

    First let me say, i know this topic has probably come about before. I even remember reading it but not taking much notice of it as it didn't affect me but I've tried searching for it and can't find anything related so here goes:

    My indicator light seems stuck, yesterday it was stuck on 99% (But says charged) and today it has done the same thing but on 97%. The first time i charged it up it said 100% but hasn't hit it again since then.

    Is this some kind of protection mechanism?

    Sorry, but your battery won't get charged unless it drops below 95%!! Perhaps you should consider using your machine without the adaptor for a few hours, it's better for the battery to allow it's electrons to flow.

    Really? I thought keeping it charged into the mains (As i use it pretty much all the time at work) would be better for prolonging the life of the battery.

    Nope. Keeping it always plugged in can make it die out faster. Here's some batter info you might want to read:

    Leaving the battery in the laptop should do nothing to harm the battery. My laptop is hottest when playing a game, and even then, the battery remains cool.

    Removing the battery decreases the performance of the laptop. There is no reason to remove the battery. What will kill a battery is never using it. If you do not use the battery, the cells in it go flat, and give you a crappy run time. I think this is a lot of the "My battery only has 50 cycles, but the health is at 40%. Why can't Apple make a battery that lasts 2 years long?"

    Use the battery at least twice a month. Fully deplete it and recharge it. Enjoy your 'mobile' computer.

    As for it losing a charge while being plugged in... I don't know why, but mine is also doing the same thing. I don't sweat it though. 3% off the runtime is not measurable with the run time of the machine. Might equate to 5 minutes extra.
