The key indicator to look for is 'current capacity', because that's what your battery has left of the original capacity (assuming the battery is not simply dead or defective).

If it is the logic board I am tempted just to sell it AS-IS. If anyone has this happen to them, I want to know what I have to replace before I go out and buy a new battery, charger, etc. I suspect this could have damaged something. As a result, I don't believe the grounding wires were making contact. I strongly suspect it is the charger and I'm anxiously waiting for a friend to get back from vacation to lend me his.Ī bit of history, before the this happened, my original Apple official charger had a stress break at the T-connector. I have reseated the battery, SMC reset, warmed the charger, and ran Apple diagnostics with no faults. I have tried everything under the sun to get it to charge again. The LED will not turn on and the battery will not charge, however the Macbook otherwise functions as normal. Exercise them periodically by unpluging the charger, run them down a ways, maybe half or so, and recharge.I am using a third party power adapter I bought off of ebay to charge my Macbook Air. I would not worry about that battery unless you are having problems you have not noted.Īs a final note: batteries are consumable items, eventually they need to be replaced just like in a flashlight or automobile. Not something to worry about, especially since the condition is rated as Normal. Voltage is ok at 11.8 volts, again noting the model and age, more typical is 12 volts, but that does vary with load and services you have running. So when the predicted life is 1,000 cycles that is a norm and not an individual guarantee. Keep in mind that cycle life is a statistical thing, the predicted life is the peak of a normal, or Gaussian, distribution. Apple has increased the ratings for the newer batteries to 1,000 cycles, while many of the older model machines had ratings in the 300-500 cycle range.

Your cycle count should be ok, again with the same comments just made.

The older machines and others noted are fine below 5000 mAh. Current MBP batteries are usually in the 6000-7000 mAh range.

What machine do you have and vintage? Reason I ask is the capacity is low for a MacBook Pro of current vintage, but would be fine for an older model or MacBook Air or MacBook. I don't know if the Macbook will discharge the battery completely every so often by itself, or if the battery is just failing and that's why it went from 100% to 4% in just under two hours while idle.Īny help or advice on this matter would be greatly appreciated. Is this an indication of a failing battery? Ever since I noticed this, the charging time indicated has held steady at ~1:13 (that's been about a half an hour now). In fact, I've run my Macbook MUCH more intensely for much longer periods of time when running Final Cut and Adobe After Effects and NEVER seen this issue before. I understand that during intense processses the Macbook will draw from the battery AND the power adapter - But my Macbook was simply idling! I can't fathom that a webbrowser and Preview would require THAT much draw for power. The power source was still displayed as the power adapter.

The power adapter light was now orange, and the indicator showed that the battery was only 4% charged. What was unusual was when I returned to my machine after 2 hours of idling (with the display asleep) to find that my battery had been almost completely drained. This is nothing out of the oridinary, and I do it all the time usually.

When Ieft, I put the display to sleep - In the background the machine was still running a webbrowser (reading an all-text page) and preview (a PDF was open). I then stood up and did some work for roughly 2 hours away from the laptop. I h ave a 15' macbook I purchased in December of 2010, and it's currently running OS X 10.6.8, if that makes a difference.Īnyhow, when I started up my Macbook and set to work, the battery was fully charged (indicator read that it was fully charge, and that the power source was the power adapter). I typically leave it plugged in while not moving around, and today was no exception. This morning I set to work on my laptop as usual.
