Ok so I am a little confused. My computer was working great it's a 15" Macbook Pro early 2011. One day it wouldn't turn on, I was freaking out! Then I hooked up my charger and it turned on except it had a X on the battery icon and said Batteries Not Available. Not knowing what that meant I googled it and was told to do a SMC restart... did that hoping it would work. No luck then I was told it was hardware problem. So I ran a test and only thing that came up was error for a battery Now the weird part. I try and look at my battery info and it doesn't even show up. Like nothing. Anyone have any ideas please??
