Empty Battery : MBP goes off instead of hibernate

[tiesto141141]

Hello !

I encounter a big issue with my macbook pro 2010 since 3 months, when the battery become empty, instead of going to sleep-hibernate, my MBP completely goes off, i don't understand why, i'm using Mac OS X Lion and i never used an app like Smart sleep,

Here is my coconut battery report :

Could this problem come from the battery that needs to be changed ?

thanks a lot

You must be the only person with a MBP 2012. Do you work for Apple?
