1000 cycles? How on earth does a 2011 MacBook Pro reach 1000 cycles that fast? Crazy! Must be that 0.000001% of the Apple-owning population that reaches such a number.


I believe that my previous battery (which was not old - about 100 cycles) suddenly died because of the same problem.
And I am far from being alone! Just lookup the "Service Battery" problem in Google: the significant part of complains about dead batteries are related to 2010/2011 MBP models, and these batteries had an acceptable count of cycles.
The whole story makes me think that Apple did not want to take responsibility for broken batteries, to admit their fault,
and that is why they set a very high number of cycles in their note.

So, I am glad that I did not paid extra money to get a new replacement battery from Apple directly
(since this problem was their fault, they do not deserve my hard earned money)
Instead, I got it from eBay top-rated seller plugplayers , $76 with shipping, and luckily it turned out to be genuine.
Was almost two times cheaper than from Apple. However, if we compare with Apple "premium" service,
there were some minor issues:
1) I had to wait the battery for about one month (was using power adapter all the time,
and because there were not battery inside the MBP, it was downclocked automatically,
probably to prevent shutdowns caused by a sudden increases in power consumption)
2) I had to buy a 38-Piece Set from DX, so I could unscrew the nasty triangle screws
(to be fair, that increased the total cost of replacement to $86)
3) I had to do the battery replacement work by myself (was not hard, really)

I wish Apple would release an updated 17" MBP. Don't need retina or DVD drive, though the improved cooling system would be nice. I know it's not going to happen, which is why I'll be hanging on to my 2011 until it dies. :mad:

Same exact thing happened to me... internal SSD not recognized at all :eek:

Did that didn't work. It simply wouldn't find my internal drive.

Had to boot into an external backup drive then try to reboot into my internal one several times before the internal drive was magically recognised again.

Thank heavens for SuperDuper bootable backups.

WTF! I had to connect it via USB then it booted... then installed it back into the machine and it is working fine. WTF Apple, WTF?

OK, just did update on my LATE 2011 model, and now max battery capacity is 6230mAh, which is 90% of original 6900mAh. I use the app coconutBattery, and I did a test on the 6th of Feb, one week ago, and had 94% capacity, or 6459mAh. I don't think I would have dropped 4% in one week. I even ran my machine down to 2% power yesterday and did a full charge last night.

Just curious, I'd like to see someone check capacity just before and after doing this update.

Similar thing happened to me. Scared the bejesus out of me. Fortunately, in my case I simply powered down (holding the power button to force it off) and booted it back up. It recognized my drive without issue and I then re-ran software update and it worked without issue.

FWIW - If anybody wants to find a commonality I'm running an Early 2011 15" MBP with OS X Lion 10.7.5.

Wheeee!
