Things to Do If Your MacBook Does Not Turn On
Adjust text size:
You turned on your MacBook, MacBook Air or MacBook Pro and nothing happens. You tried everything that you could think of to bring it back to life, but everything failed. What now? Most individuals would just pack it up and leave the people at the Apple Retail Store or an Apple Authorized Service Provider to deal with it.
Other people would just try to find a solution on their own using the powers of the Internet and all the pieces of advice they can get related to their problems. They will try anything they can find about the exact problem their MacBook is experiencing, and some of these people might discover a way to make their MacBook come to life on their own.
While this second approach might prove successful for a small percentage of the total number of individuals going this way, for the rest of them, it might just get their portable Macs into more trouble than the initial issue did in the first place.
Regardless of the category you fit in and your Internet search prowess, according to a short support article published here
, there are a number of safe and Apple-approved procedures you can go through to make sure your MacBook needs that trip. First tip
If your MacBook does not give any signs of life, simply disconnect any peripherals connected to the system (printers, hubs, and even 3rd-party keyboards or mice), and give it another run for the money by trying to turn it on. If it all goes well and your MacBook starts up now, you at least know that the problem was due to a defective device connected to your portable Mac. Second tip
Try unplugging the power adapter from both the electrical outlet and from your MacBook, MacBook Air, or MacBook Pro. Now, make sure the power outlet the MacBook was connected to works by plugging it in any electrical appliance you have nearby. After unplugging the test electrical appliance and verifying that everything is OK with the electrical source, wait a minute or two and just plug the power adapter back into your MacBook and the power outlet.
When you do that, the LEDs on the MacBook’s connector should light up green or amber (depending on your machine’s battery-charge level). If this does not happen, you now know that your battery is drained and that the power adapter is defective. Third tip
Should the portable that is giving you all these troubles be a MacBook or MacBook Pro, you can give it a quick and easy battery-level check. To do this, you have to press the small button on the battery or on the side of your MacBook. Next, you should see the lights that indicate your computer battery's level of charge.
In case you see only a single light blinking, you know that the one responsible for your dead MacBook is the battery, which you now have to recharge by plugging in the power adapter connected to an electrical outlet. Fourth tip
Another possible problem could be a MagSafe port not working correctly. Look for any kind of debris inside it port that might prevent it from connecting the power adapter correctly to your MacBook. On the adapter, take a quick look at the DC connector for any type of debris and carefully check if any of the pins are missing, are bent, or stuck down.
If you come up with results after any of these procedures, go to Apple’s support website to the 'Troubleshooting MagSafe adapters
' article and follow the available instructions on cleaning the adapter yourself. Fifth tip
This is the simplest way to make sure that your MacBook is not just stuck because of an operating-system flaw. All you have to do is press the control key, the command key, and the power button at the same time and hold on pressing them for about three seconds to try to restart the computer. If this works, you now have a functioning MacBook and you know that everything was OK at a physical level. Sixth tip
Out of all the people that have trouble powering up their MacBook’s and end up at the Apple Retail Store to solve their problem, a good percentage are using an adapter that was not designed for their computer, an adapter that is not able to charge their Mac’s battery and that, thus, renders their computer unusable.
If you have changed your MacBook’s power adapter and don’t know which one is compatible with your computer, go to Apple’s support website (http://support.apple.com/kb/HT1565) and find that out
If everything mentioned above has failed, you can try to reset your portable Mac’s SMC. As Apple says in a support article published here
, on MacBook and MacBook Pro systems, you can do this by removing the AC power, taking out the Mac’s battery and then holding down the laptop’s power button for five seconds.
If you own a problematic MacBook Air, press the (left) Shift-Control-Option key combination along with the power button once. Important: you must use the keys on the left side of the MacBook Air keyboard. Eighth tip
Apart from resetting your MacBook’s SMC, Apple has also published a how-to
piece on how you can also reset its PRAM if your Mac experiences problems. First press the power button and then hold down the Command-Option-P-R keys simultaneously, until you hear the startup chime at least one additional time after the initial sound.
If you tried to upgrade your MacBook’s memory before experiencing start-up problems, you have to make sure that the installed memory is compatible with your computer and, if this is so, check if the memory is correctly installed.
If everything is OK with the additional memory and the MacBook still does not want to turn on, remove the new memory and see if it starts up properly without it. If it does, you have found the culprit for all your problems.
If the above procedures don’t work for you and your MacBook is still as dead as before, all that remains for you to do is the inevitable: schedule a service appointment with either an Apple Retail Store
or an Apple Authorized Service Provider
Should you have further tips that might get others out of trouble when their MacBooks are acting up, share your knowledge with us and the readers in the comments.

I thought I would find something different on here but it's pretty much the same as what Apple has on their website.

Very helpful, but what worked for me was putting my MacBook in the freezer for 10-15 minutes to disipate the excessive heat.

One question, if l open the back of my mac book and remove the battery and reset my SMC, will that make my warranty void, is it still under warranty if l open it?!
|Comment #13.1 by: Sergiu Gatlan on 07 Oct 2011, 11:41 GMT|
It depends on the kind of MacBook you have. You can see at http://support.apple.com/kb/ht3964 the exact procedures to follow if you want to reset the SMC safely and without voiding your warranty.

Good tips, but does not contain the tip that worked for me; have memory -only- in the right slot (i.e. remove memory from left slot)
|Comment #17.1 by: Sergiu Gatlan on 29 Nov 2011, 13:37 GMT|
I tried to cover the more common cases. The fact that your MacBook turned on when you removed the memory from the left memory slot might be a sign that that memory bank has serious problems.
You should think of scheduling an appointment with an Apple Authorized Service Provider (before your MacBook's other memory bank goes the way of the dodo too).

I had the same problem and I went to the apple store and the problem was the Magsafe power adapter. They told me that i have to replace it because the one that I have is 65W and I need the 85W MagSafe Power Adapter for 15- and 17-inch MacBook Pro Adapter, since my is 15-inch so I replace it and also the battery was in bad shape too.
|Comment #21 by: SamY on 10 Jan 2012, 16:52 UTC|| reply to this comment|
Great article, but unfortunately none of these worked for me. My MacBook Pro simple will not turn on at all....no response from the power button at all. I am taking it into the Apple Store tonight to have them look at it. I surely hope that it is not the logic board. I got an estimate for a new replacement bd for $699.....YIKES!!!! My unit is 4 yrs old.
|Comment #21.1 by: chuks on 16 Mar 2012, 20:10 GMT|
My Macbook could'nt power on barely a few minutes after the system was properly logged.
|Comment #21.2 by: Murdoc on 21 Mar 2013, 00:18 GMT|
I was told that my power button itself is the problem. The unit is less than 2 years old. I phoned AppleCare and told them about it; they said it was out of warranty and that they could do nothing. Shame. My first MAc was a 512 and never have I had issues like this.

Ok so my macbookpro just decided to turn off and it does not turn on and when i try connecting it, the green light didn't even turn on! So i tried EVERYTHING on this page and it didnt work D: SOMEONE PLEASE HELP ME DDD: !!!
|Comment #23.1 by: Sergiu Gatlan on 19 Mar 2012, 13:41 GMT|
If none of the above worked, all that remains for you to do is the inevitable: schedule a service appointment with either an Apple Retail Store or an Apple Authorized Service Provider (just like I said at the end of the article). It seems that your MacBook Pro is indeed in deeper trouble than you can fix on your own.
|Comment #23.2 by: Jandy on 21 Apr 2012, 13:29 GMT|
I had the same problem with my macbook pro, I brought it to the apple store for service and guess what, they said I need to replace the logic board that costs 3/4 the price of my mac.
|Comment #24 by: JDonRocks on 20 Apr 2012, 01:07 UTC|| reply to this comment|
Battery is fine, power is fine; when pushing the power button on my Macbook Pro the light turns on in the lid switch, the hard drive cycles then nothing. Normally the chimes sound and the screen comes on and the fan kicks off. If I hold L-Shift it does the same but plays the chimes with no other difference.
|Comment #24.1 by: Macattack on 16 May 2012, 09:26 GMT|
Hey mine does exactly the same thing. Everything was working fine last night and I shut down properly and then this morning this happened. I tried out all the tips here but nothing seems to work. I press the power then I here the mechanics working and the year the drive and then just a blank screen with the sleep light on the lid button. Any solutions to this problem? Thanks in advance!
|Comment #24.2 by: Sergiu Gatlan on 16 May 2012, 11:03 GMT|
It seems that your Macbook Pros have a faulty logic board that needs replacement.
Go to an Apple Authorized Service Provider to see exactly what you can do about it and if there is no other solution to your problem

Fifth Tip: I help down the control+command+power button for about 5 seconds gave me a loud bahhhhhhmp noise and shut off....again. Why won't it turn on? :(

Apple has let me down once again....spent over $10k on a power mac and macbook pro, only been 3-4 years now both logic boards and cpu are gone on both of them....unbelievable .....my pc 10years later still going, for less than half the price of my apples.

|Comment #29 by: Rob Wiltshire on 20 Jul 2012, 04:43 UTC|| reply to this comment|
My Macbook was lifeless after the battery went to 0%. I couldn't charge the battery or switch on the Mac. Then I found it started up when I did the following... (very carefully)...
Remove the back...
Learn how to unplug the battery - then reconnect the battery.
Connect the power supply...
Unplug the battery...
Press the Power button.
I'm guessing that the Mac checks the presence of a battery when the power supply is connected but refuses to start up when it detects the battery is at 0%. Unplugging the battery after the power supply is connected stops the Mac detecting the battery is at 0%.
This method is good to power up the Mac and recover files but it will not solve the problem of getting the battery charged.
It worked for me and I hope it works for you.

I had restarted it about 25 times, then I turned it off, closed the laptop, opened it again then started it up, then it worked.

Thank you so much. I'm a college student who needs my MacBook Air for everything academically related, and it died on me when I was studying :O. Luckily, I found this article (what a god-send) and the 5th tip brought my baby (yes. I am very attached to my Mac) back to life and saved me for the exam. Thank you so much!!! :) xx

|Comment #39.1 by: Nini on 06 Dec 2012, 06:49 GMT|
I know this sounds insane and silly but I tried everything in this article.. Nothing helped.. Until I got pretty * off held down the power button and swiped my hand back and forth on the entire keyboard... And it finally turned on! Thank The Lord lol.. Good luck!!
|Comment #39.2 by: keyfreeworld on 16 Dec 2012, 10:36 GMT|
Hi, I've tried all relevant tips, but I'm still only getting the first part of the start-up sound, but then it switches itself off just before the chime should sound... does this give any extra clues?
|Comment #39.3 by: Sergiu Gatlan on 17 Dec 2012, 12:03 GMT|
@keyfreeworld & @Ms.Eyes31: You should schedule a service appointment with either an Apple Retail Store (http://www.apple.com/retail/storelist/) or an Apple Authorized Service Provider (http://support.apple.com/kb/HT1434).
|Comment #39.4 by: Cjasmins on 19 Dec 2012, 19:36 GMT|
My macbook pro had the same problem and the solution that worked was the one said by nini! It can sound insane but it really worked! Thank you!
|Comment #39.5 by: Mrs. E on 26 Dec 2012, 19:40 GMT|
Mine was completely unresponsive... I tried Nini's trick of holding the power botton and swiping all the keys and-- YES! It really did work for me!
|Comment #39.6 by: BF on 18 Mar 2013, 00:59 GMT|
OMG! This actually worked!!
|Comment #40 by: Keyb Damage on 23 Dec 2012, 01:51 UTC|| reply to this comment|
I had a Macbook pro that didn't turn on at all. I was able to turn it on bypassing the power button by jumping two points right near the trackpad connector. Had to remove keyboard ribbon for it to work though. Lookup the exact spot for your particular model.
This will work if your keyboard has been damaged, as the power button is part of it.

hi can anyone know how to repair an apple macbook pro?? a liquid enter inside my macbook pro.. i i try fixed it by not turning on my book for a month..but when i turn it on it wont open anymore..can anyone help me..
|Comment #41.1 by: Keyb Damage on 30 Dec 2012, 16:03 GMT|
Same thing happened to me, the power button is part of the keyboard, so water damage can make it not work. You can try opening the bottom cover and manually 'short' the power button, look it up for your particular model.

|Comment #43.1 by: Sergiu Gatlan on 07 Jan 2013, 15:30 GMT|
From what I can tell out of your description, your Macbook Pro seems to have a faulty logic board that needs replacement.
You should schedule a service appointment with either an Apple Retail Store (http://www.apple.com/retail/storelist/) or an Apple Authorized Service Provider (http://support.apple.com/kb/HT1434) to see exactly what can be done to fix it.

Hi, i tried everything as you instructed but nothing seems to work.
Whenever i push the power button the light turns on and i can hear the disc drive making a sound as if it is booting but it only lasts 2 seconds and then it turns off instantly. When i start it up by holding the power button it lasts up to 5 seconds and it blinks before it dies.
-battery is fully charged
-power cord is working well (tested it with another mbp)
-i use this mbp daily as a desktop computer and i seldom turn it off even at night.
i already tried SMC reset, PRAM reset, i already removed the RAMs -switched and inserted it one by one.
|Comment #46.1 by: Sergiu Gatlan on 11 Feb 2013, 15:09 GMT|
Just like in JayFed's case, I think that your Macbook Pro has a faulty logic board.
