My Macbook Pro Retina shuts down when not connected to the charger.

My macbook pro retina (10,2) shuts down whenever I try to work without it being connected to the charger. It has a full batteri but whenever I unplug it, it shuts down efter 5 min - Completely shuts down.

I have tried to reset the SMC.

This is info from my MBP:

Boot ROM-version: MBP102.0106.B07

SMC-version (system): 2.6f59

I have tried to check the my energy saving preferences but nothing helps.

I have recently downloaded the yosemite update. Dont know if this could be a reason.

How do I fix this?
