Won't start up; charger blinking orange

The solution that worked for me was leaving it unplugged overnight.

I Have tried everything.. Read and searching for help to awake my mbp.. This is the one that so helP.. Thank you thank you thank you.! I dont have to send my mbp to the shop for repair.. I do it myself and it's already back.. dbartul you're owesome. Love you.!

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 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

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!!

It will make it easier to help you w/ your problem to know know more information about your computer; size, exact year built, RAM installed and OS you're running. Any history prior to your incident would also be helpful.

If the battery is removable you could try:

Try a hard reset. Disconnect the battery (open the bottom and pull the connector off. Use your fingernails.) and power adapter. Press the power button for 1 minute. Let the computer sit for 5 minutes, Reconnect and try to start up.

No? - Go through the same procedure and try to start without the battery connected.

The addendum to this would be to try a known good battery.

This would be for a "no start" scenario but basically it's the SMC reset w/ a battery you can remove.

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!

Had the same problem and was really worried. Thanks to dbartul it works again!

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.

I just logged in to say thanks to dbartul!!

My daughter's mid 2012 13 "MBP started this behavior yesterday. I tried resetting SMC, etc. and nothing. I made a genius bar appt. but continued searching and came across this post, worked like a charm!! Saved me a trip to Apple Store, I am SO grateful!

Just why its not working with me i started to lose hope please help me guys

This post was a saviour. I thought my mbp was a goner but the helpful replies saved all the time, effort and energy of having to go down to the store just to get it checked. Thank you.

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