Mac Book: Battery not Charging

Okay... Last night I was working on my Macbook for quite late when suddenly I couldn't continue and was so sleepy that couldn't save my work and shutdown my Macbook. So with sleepy head and almost closed eyes I put my Macbook on "Sleep" mode and went to my bed. After three-four hours when I woke up in the morning I again opened up my Mac and continued my work. Only 15minutes would have passed that my Mac got suddenly turned off. I tried to pressed buttons on keyboard and tried to wake it but no use. It was pretty shocking for me because it never happened before. Battery was almost full and Charger was plugged in. I restarted the Macbook, it got turned on but now the Green LED of my Magcharger had been tuned off. And there was X sign on my Macbook battery. The status was battery not charging. I went to the system info and checked the power. And it was something like this :

In confusion I couldn't think of anything so just "Restarted" my Mac, but nothig changed. Shutdown: didn't work. Put it to Sleep mode and then woke it again, still nothing worked. I unplugged the Magcharger still nothing happened. But luckily my mac didn't shutdown after removing the charger. So it gave me little relief. So I thought of Resetting "System Management Control" (SMC).

In some situations you might need to reset your computer's System Management Controller (SMC). Below is the method given to reset SMC on most modern Intel based Macs, which do not have removable batteries. 

Before doing SMC on Macbook pro make sure you have already tried all the above mentioned procedures. 

How to Perform SMC on Mac?

Here you can find the steps to reset the SMC on macbook pro:

Yess, Now when I turned on the Macbook my battery was up and working again :D
