    Check Your Cycle Count

    I did the Calibration routine, and after the machine went to sleep I was unsure if I actually shut it down. I held the power button for some ten seconds or so. In any event the recalibration had no effect on the service warning alert. Found this article very helpful! Getting a new charger did it for me! Essentially, you just have to shut down the computer again once more. I followed the steps exactly, and when my computer turned back on it still had the warning.

And thank you, my macbook pro from , started showing service battery out of blue and the cycle count was only and I tried SMC reset and it still did not work. I tried the second option of draining and recalibrating the battery, it still did not work. I even switched off, after it slept by itself. And waited for 6 hours, before plugging and rebooting. But the apple service advisor also suggested to go to repair and with 2 deadlines approaching and no other way to work on computer, it would not have been possible.

I had an authorized apple dealer replace my battery within the last 3 years and I have the Service Battery warning. I have noticed that my battery drains very fast, so I am constantly having to leave it charged or plugged in. If I try the recalibration, like you, I am hoping that it will help to solve the the problem of it not draining so quickly, regardless if the warning goes away.
