Won't turn on unless plugged in but shows battery charging?

Earlier this year my battery stopped charging (I used a genuine Apple charger then) and I watched the power dwindle to 0% until it died. So I bought a replacement charger which didn't help (60W). The Genius Bar said the left I/O board wasn't picking up a charge from MagSafe connector so they replaced the board. Three months later it died again so I bought a left I/O board and just replaced it myself.

Sadly it does sound like the battery has died. You could give this free app a try to see what it tells you coconutBattery. While it can't fix your battery it can at least tell you if it has any life left.

"Well I can tell you it's NOT a dead battery.

I have the exact same problem with my old Macbook Core Duo.

I have several old batteries and a couple of new ones, and all cause the same behavior.

1) All batteries will charge

2) Adapter LED goes from orange to green, and the batteries peak at 97-100%

3) Macbook will only turn on when plugged in.

4) If not plugged in to AC, Macbook will spin up the drive, no chime, then spin down.

Of what I can find online, it's either something wrong with the battery connector circuitry, although everything, even coconut battery utility, says everything is within normal limits. Or it's the logic board."

"Try resetting you SMC (system management controller)

hold down the Shift+Control+Option keys and the Power button at the same time

"Confirming similar issue for Asus Zenbook UX32VD (experiencing it since ~2015, so when the laptop was about 3 years old). I first thought it is a dead battery so I bought a replacement - but only after a day or two the new one started behaving like the old one.

It was always the same ... the battery charged to 100% when it still worked and after some time it went right down to 0% if unplugged or stopped at some percentage when plugged in, but didn't charge. When I turned the laptop off and unplugged it I could no longer start it unless plugging it in again and at that point both Windows and Linux told me I am at 100% yet the battery was flat and not charging any more.

Then I found out if I unplug the battery from the computer and let the laptop start without it the next boot with battery plugged in again almost always made the battery really charge to 100% (starting at a low number below 20%). But unfortunately this ""fix"" only lasts a few days at most and then the whole process has to be repeated in order to make the battery work.

So I suspect in my case this has something to do with the laptop itself and it is not a battery issue."
