Things to Do If Your MacBook Does Not Turn On

thank u, the fifth tip worked for me

yes the 5th worked for me lifesaver thought it was logic board,
this has made my night
CHEERS

Thanks a lot. I was panicking and this 5 trick worked. Oh god saved £35 phone help.

None worked. :(

The eighth tip worked for me. THANK YOU!!

This story was a huge help and well written. I read it from my cell phone and found the magic keystrokes that rescued my system before an important meeting. (It was step 8, incidentally.)

Thank you and I'm glad that it helped :).

None of these tips worked for me. Finally, I removed and re-fitted the battery and it worked.

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.

Thanks man, I try everything, in the end I try freezer and work it! :D

Hi, if it is 5th tip that helped, what is the cause for the problem? I have had this problem for the 2nd time in 4 days. It doesnt happen all the time, but I am wondering how I can fix it for good.

my macbook , first starting changing from a normal display at startup to a kind of safe-mode resolution and after a day of that, it wouldn't boot up., nothing from the power button. My power adapter stays green, but the power button doesn't work. What the hell is going on

Thanks a bunch. The fith tip was very useful XD

well written amazing post thanks alot!!

This Article solved my problem. Thank you so much!

I was about to throw away my Macbook until I tried 5th tip and my Macbook came back to life! Thank you!

It was so frustrating not having the laptop work as wanted.....great help here. Thank you very much. Tip nr 7 did work for me!!

5th tip worked perfect for me thanks

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?!

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.

this i my third time this has happened with almost new macbook air - what a load of crap; unbelievable - never happened with toshibas

good good good good good

You are the one dude..you save my time and money with your tips. thanks a lot.

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)

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).

Very useful. Able to turn on my MacBook Air after simultaneously pressing the control, command and power keys for 3 seconds. Thanks a lot! Taipei, Dec. 1, 2011

#8 helped

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.

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.

My Macbook could'nt power on barely a few minutes after the system was properly logged.

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.

This is great my computer works now!

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: !!!

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.

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.

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.

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!

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.

Thank you tip 5 work! You saved my life - big presentation due in a few hours. Ann

Thank you!! Saved my day

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.

Excellent help. Thanks. Peripherals were the issue.

Fifth tip helped me, thank you soo muchh!!

Thanks the fifth tip worked like a dream

None of these tips worked. Going to Apple.:(

love you !!! tip 5 worked for me

Saved my * ! Thanks!

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

Thank you. It worked!

My mac book pro indicate that the battery is fully charged and it still will not come on can anyone help me...???

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!!

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?

@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).

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!

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!

OMG! This actually worked!!

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..

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.

I'm not sure what to do I was on my MacBook Pro it was quite hot it randomly shut off I went to feel the charger it was normal my MacBook Pro was normal as well I tried turning it on and it wouldn't turn on I plugged my charger in and the small white light that faces towards you continuously was blinking it didn't make any noise the colour of the charger was amber and the whole time I was on my MacBook Pro it was charging I don't know what happened please help soon

My MacBook Pro will not turn on it shut down on me randomly while I was on the Internet and thn it would not turn back on I plug my charger in and the white light at the front continues to flash and in flash like its trying to turn on but it can't I really need this MacBook please anyone HELLLLLPPPP

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.

The fifth worked great- Thank You

Thank you very much, the fifith one worked for me as well. Thank you again.

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.

Please help!!!

Just like in JayFed's case, I think that your Macbook Pro has a faulty logic board.

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.

I plugged in my Galaxy note 2 to charge it (usb) and there was a crack from my macbook pro 17" and it died dead capoot, oh sh_t I said, anyway after searching for a solution I came across this website, I tried everything and last resort unplugged the battery for a couple of minutes, plugged it back in and pressed the power button and it burst into life and all is back working again, so thanks very much to the person for writing this.

I tried all the above tips,but still its doesn't wanna on

Thanks so much! I WAS FREAKING OUT lol but the 5th one helped me out. I just downloaded Mountain lion yesterday and I'm guessing that's why. Thanks again!

my macbook wont charge ,it led wont light on orange or green and wont power on what do i do ?

What if the power's drained. What do you do then.

Thank you for the 5th tip - it worked for me :)

A magical list of what one should do in such a situation! Amazing!

The 5th tip worked-on the second try. This is a recurring problem. I have tried Tip #8 before but it seems not to work. Any thoughts? Thanks very much for the tip list!
