Hi Everyone
I have noticed that my Acer Aspire E5-521 shuts ff when it reaches 40% battery power. 
When i plug in the ac adapter - it shows me that it is charging from 7% battery power
That's weird - how come from 40% to 7% 
Does anyone know what's going on and how i can fix the problem

Thanks
Gabe
