Won't start up; charger blinking orange

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!

Cheers dbartul, saved me a trip to the apple store.

Wow, Super thank you dbartul! You save us from going to Power Mac Center. I thought my charger is broken. Tried what did you said and voila, Im using my macbook again right now 🙂 Charging fine also. Thank you so much and Godbless!

dbartul; still saving the day over a year and a half later!!

This happened to me also. I'm going to summarize what I saw elsewhere and what worked for me, for the benefit of humanity.

The symptoms I saw were that my macbook pro completely shut off. Importantly, this happened suddenly as I disconnected my iPhone while updating to iOS 8.0.2, but I was using a third-party USB cord. The laptop's power button no longer yielded any response at all. When I plugged in the power cord, the LED was extremely faint and blinking between green-ish and orange-ish. I could even hear a little actuator clicking inside the power cord when the LED switched color.

A lot of people suggested that simply leaving your macbook pro unplugged for 30 hours would drain the battery. Then upon trying again, the thing would work. I tried this and it did not work for me.

Then I found several other people saying that the same symptoms occurred after they had plugged in their iPhone via third party USB cable. The fix from this crowd did work: open up the bottom of your macbook pro and disconnect the battery from the logic board for ~15 minutes. There's only one connector (a ribbon plug fed into with a row of little black wires) between the big black battery and anything else, so this shouldn't be too tough to find.

Anyway, this worked for me and I hope it works for you!

I Cant Thank you enough dbartul!!!

make a long story short i plugged a third party iphone usb cord while the computer was in sleeping mode, found out i made a big mistake!

computer went black out shut down completely would not respond and the power button not working, no reset is working and the button on the side to check the battery was not even showing one light like usual.

i googled about megasafe blinking orange light came to this threat and found the solution witch worked perfectly, just unplug, replug and walla MAGIC!!

thank you guys!

Yep, unplug the battery connector and it works, here is a like to iFix it if you don't know where the battery connector is, I had the same issue with my 13 inch Macbook Pro Unibody Mid 2012, thanks for that tip dbartul.

here is the link for ifix it if anyone needs it. www.ifixit.com they have a tutorial on how to disconnect the power cable. very easy to do.

thanks dbartul! Worked for me!! Turns out it was because I used a cheap USB cable to charge my iphone. Now I'm never gonna use that cable again!

Worked a charm, many thanks

Hi folks,

I need your help,

Here is my issue : One day my MBP was telling me to replace my battery " Replace your battery soon " and off course I did not replace it.

Now my MBP isn't booting and when I plug the charger in, the charger light is blinking sometimes orange sometimes green.

I noticed on the left edge, all the lights indicating the battery life ( 8 smalls lights ) are blinking green. As soon as I press and hold the power button, these 8 lights stop blinking and start back when I release the power button.

I tried several times the fix you all did and nothing seems to help.

Do I need a new battery in order to use my laptop back or Should I be able to use my MBP with dead battery using the charger only ?

Thank you for your time.

I just came here because for the past 4 hours I have had a flashing yellow light on my charger.

Turns out I haven't pushed it all the way into the plug! It's solid Orange now!

Thanks dbartul, that worked for me too! 🙂
