Won't start up; charger blinking orange

Came home from work and went to turn on my late-2011 MacBook Pro. It won't start up. Nothing happens (no tone, no motor noise, nothing). When plugged in (MagSafe power charger that came with the unit) the charger unit blinks orange. Tried the charger on my other computer - works just fine. Tried 2 other MagSafe power chargers (from other Macs I own/have owned) and all act the same way with this computer, but work just fine with another Mac.


Anyone have any idea what's going on? I have owned Macs since 1988 (over the years I've owned a Macintosh II, Macintosh Performa, Power Mac, Power Book, and another MacBook Pro before this one). I've never had a problem like this one before...HELP!


[A side note: There have been NO spills, no tumbles, no falls, nothing to prompt any sort of issues....This was a completely RANDOM "dead" laptop!]

MacBook Pro (13-inch Late 2011)

It could just be your system management controller. Try resetting it using the following procedure:

Resetting the System Management Controller (SMC)

Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).

  1. Shut down the computer.
  2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
  3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
  4. Release all the keys and the power button at the same time.
  5. Press the power button to turn on the computer.
    Note
    : The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

If that doesn't give any love it may actually be a battery problem. The part may just have been defective. Manufacturig isn't perfect, especially when you introduce things like Humans and Fridays. 🙂 That is why we have warranties.


Hopefully the SMC reset helps!

I don't know how many like you would get for this quick fix. It happened to me today...my laptop was fully charged and my wife moved to the next room and screen went blank. For me it was blinking green instead of blinking orange. I am assuming blinking orange for battery that is depleted whereas blinking green is for battery that is changed but not supplying power to the motherboard.


In parallel i called up apple store & they gave me an appointment tomorrow @ 4.00 PM whereas I have an international flight to catch the next day. They would have definitely charged a lot of money for this asking to replace parts. You saved my time....thanks a Ton!

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 also had the issue (Macbook powered down and power cable light blinking orange) happen when plugging in a 3rd party lightning cable for my iPhone 5s while my Macbook Pro was asleep. I heard it instantly power down (whirring slowing from fans).


However, dbartul's fix worked exactly as so many others said. It is tremendously easy compared to other fixes and upgrades I've done (one was replacing the bulb in a Macbook screen...not recommended). First time I opened this MacBook Pro of mine.


When I rebooted and started iTunes again, I plugged the same 3rd party cable and it didn't have the same effect. I'm wondering if its only when the MacBook Pro is asleep or maybe the connector is just fidgety and will randomly cause problems (as others have described). The issue is definitely related to plugging into the USB but I'm not sure its just a 3rd party cable that would do it. It seems there is a safety breaker that trips the system when it tries to manage the power supply to the USB.


My advice would be to only use 3rd party cables for charging and use the original Apple cable to connect to the MacBook. Unless someone has other advice or evidence that its only when the Macbook is asleep?

I have a solution! Three weeks ago I purchased a replacement charger from Apple and it just began the blinking "green and amber" after working like a charm for the first 3 weeks. I disconnected the "cord extender" and reinstalled the plug on the Charger....plugged it back into to the wall and it WORKED! I just will not be using the "cord extender".....

I have the exact problem! Last night, I plugged in a USB Camera, My mac showed a kernel panic (first time ever) It wouldn't restart. I tried plugging it in and fixing it this morning, But the charger started faintly blinking green and orange, something I've never seen before. I don't want to take it apart. Please Help!!! I'm so worried, I hold the power button, Nothing!!! Not even the little white light on the side! I'm so worried! If I really need, I'll take it apart, I'll do almost anything to bring it back to life!! HELP!!

Oh my GOD! Thank you thank you soooo much! I am a teenager so as teenagers do my Macbook Pro 2009 got taken away except it was accidentally left untouched for over a year! I got it back and it would not turn on and I was panicking and I saw this yesterday but was too nervous to open the back but tonight I got bored and nervously tried it. It worked the second time when I took someone's comment on leaving it disconnected for about a minute. Thank you SOOOO MUCH!

Thank you so so so much for this info. It totally worked for me.


Abit of info... My MacBook crashed when I plugged in my iPhone to back it up. I do suspect the USB cable may either be faulty or a counterfeit cable 😟


the screwdrivers needed are for sale at Screwfix in a fab forged steel kit for £9.99. It's the Phillips PH000 head that worked for the screw heads used.
