Had the same problem with my MacBook Pro 13" (Late 2011), switching adapters didn't work, SMC reset didn't work and I was just about to quit trying and take it to the shop when out of frustration I've unplugged the battery connector and plugged it right back in and that FIXED IT!!

(note: do not remove the battery since that will void the warranty, just remove the connector)

THANKS dbartul it helped me a lot!

I plugged my iPhone 5S into my MacBook Pro a few minutes ago and it blacked out. Saw my Magsafe adapter was blinking amber, the Google brought me here. This saved me from losing it when my MacBook would not power on. Disconnected and reconnected battery cable and it fired right up. Thank you dbartul!

"Is it possible that the MagSafe DC-In Board adapter is damaged or not working properly?"

Yes this can happen but it's rare usually it's the battery itself. Did you try a start w/o the battery connected?

there's a little cable going from the battery to the connector on the motherboard (low right corner), you just have to unplug it and plug it right back in.

Thanks so much!! reset battery connector and it worked!! saved me a half day trip tomorrow to Apple store. Lifesaver! Thanks!!!!

I Had this exact issue and fixed it. I let my battery completely drain over 24hours (not plugged in to charger). after the 24+ hours plugged it back in and boom sorted

Hi sharon681,

It would help us to know the year made and the size of your machine.

Go look on the bottom of your machine, pull the serial number and run it here:

You'll have to go in again and unplug the battery. This time leave it unplugged ( You might have to cover the plug with tape. These plugs have a tendency to replug themselves when you flip them upright. I use Scotch Blue painters tape or the equivalent.) Using just the the power adapter, try to start it again.

A defective battery or power adapter can cause this symptom. So use another power adapter and see if that works. What's the wattage rating on the power adapter? ( Written on it.)

NO! unplug battery conector and plug back in again, no need to remove the battery. Just thought I would clarify, dont want someone taking out there battery for no reason

Thanks @dbartul! Your trick worked for me as well. Same issue with my MBP and unplugging the battery from the board did the trick!

THANK YOU SO MUCH!!!!!!! You just peel the battery connector up then press it down till it clicks and VIOLA!!!!! Thank you thank you!!

Remove charger from your MacBook Pro, remove the 10 screws from the bottom, take off the back, unplug the connector ( I posted a pic of it), plug it back in again, put the back on and turn your MacBook Pro on it should work

@dannykool, you might try doing it again but wait a few minutes before reconnecting. Here's from an earlier post of mine:

...."Not remembering which cable I was testing when it went dead, I started testing them again. When I got to the bad cable, my Mac instantly went dead! So I did the battery disconnect. This time it didn't seem to work. Oh cr#p!. Tried again. No go. I disconnected the battery a 3rd time and, thinking maybe I'd forgotten a step I got on my other computer to review but didn't find anything. Went back, re-connected the battery and immediately connected the charger. Success!! I'm not sure if it was the extra time the battery was disconnected or the fact that the charger was connected immediately (or maybe some other factor), but the bottom line is don't give up if it doesn't work the first time.

Also, as I found out the first time, the clock gets reset to some time in 2000. Depending on what programs are going to restart (Safari being a prime example) on startup, many will not be happy with this! So the second time I logged into the Guest account and reset the clock before logging into my regular account....."

Hope this helps!

Unplugging the connector worked for me as well. I had to do it twice. It didn't work the first time so on the second attempt I waited about 30 seconds instead of plugging immediately back in. Thanks for the fix.

Anna,

For me also, it was plugging in a non-apple approved iPhone cable that crashed the battery. I didn't realize that that was the cause and so I did it again and crashed it again. My post about it is a few pages back. The second time it seemed not to work but it turned out that you need to wait a minute or so befor plugging the battery back in. If you are timid about opening your computer, macsales.com and ifixit.com have video tutorials.
