    hello guys,

    yesterday, my mac suddenly shut down.
    i power up and it run but it shut down immediately.
    i have tried many times and it still doesn't work.
    i plug in the charger, it's work!
    when i plug out the charger, it shut down immediately :(
    i have checked the battery is full

    now, i can use it without charger but it may shut down immediately...

    Sounds like poor contact between the battery and the contacts on the case.

    Try resetting the SMC, the Apple website will tell you how

    Also look in About This Mac > More Info > Power

    Does it say battery installed - Yes?
    Under battery health it should say "normal" & a cycle count. What does yours say?
    What does it say for Full Charge Capacity?

    Almost certainly a bad battery.
    Under battery health it should say "normal" if yours says "Check battery" that's a bad battery.

    You have 1558 cycles, that's a really old, really tired battery. Apple says they will go for 1000 cycles.

    Also your voltage and max capacity are very low. Bad battery.
