Hi all,

I have a great MacBook Air mid 2013. Worked perfectly until today, battery worked very well.
But few hours ago, every time I unplug the power cable, my mac shut down within 10-20 sec. I tried to reset the SMC system but nothing changed.
As it appears in the System Information, the battery is in "Normal" shape (see screenshot attached)

How can I tell if I should replace the battery? Can anyone help?

Thanks,
Michal
