MacBook Pro suddenly doesn't turn on.

My MBP suddenly stopped working.
It was sleeping and when I decided to use it, it doesn't turn on at all.
The charger's LED indicator doesn't work either, or any of the lights in the computer.
I don't know if a SMC reset can help fix it? Help..?

Macbook pro 13 doesn't turn on

I have a macbook pro 13, 2 weeks old. I was working with it while plugged in to the power cord then I turned it off and kept the battery charging. After the battery was almost fully charged I unplugged it and when I tried to turn it on I see the power light blinking but nothing comes on. Can anybody tell me what could be the problem?

Troubleshooting a MacBook, MacBook Air or MacBook Pro that won't turn on

My macbook pro suddenly freezes; screen turns off and computer freezes. Have to hard restart. Error message appears upon restart, saying something about kernel, etc. Can anyone please help on this issue?

For the past month or more I've encountered what I consider to be quite a serios problem with my Macbook pro. The laptop suddenly freezes without warning, the screen turns black, while the hard drive apparently stals and the system no longer responds. The only way to resolve this issues is to restart the computer via a hard reset. After restarting, an error message box shows up asking me to report the error, which I've already done on numerous occassions. The problem occurs at a frequency of 1 every 2-3 days, sometimes more often than that. The error message that comes up is very complicated but contains some key words amongst which includes "kernel." This makes me believe that it's an issue with the video card, and was wondering how I can remediate this problem so as to get the normal function of my laptop back. If anyone can be of any help, I would greatly appreciate it.

Macbook Pro Screen doesn't turn on?

So, I have a late 2011 Macbook Pro 15". About two weeks ago, my macbook screen just stopped working. I shut it down, and since then it's been practically "dead". The display doesn't turn on, the logo on the back is off; Essentially, the whole display of the mac doesn't get powered on. However, the startup noise is still there when I turn it on. I've been using it in a monitor as of now and it works fine with the monitor. This is the thing though, the screen is perfectly fine!! About a week ago in the morning when I turned it on, the display turned on. the screen had been white, and the apple logo popped up, it looked completely fine. Sadly I had to go to school and when I came back, no matter how many times I restarted it or did anything to it, the screen would just not turn on. Yesterday, I was showing my friend and restarted it, turned it on, then nothing. Tried it again while doing random keyboard strokes and the display turns on. Excitement in my eyes, it actually restarts and for the first time in two weeks I was to see my desktop and see my mouse moving around, all the icons, everything! The display and everything on it was working perfectly normal, no noise, no distortion, no odd colour, no issues on the display at all. My friend boots it to windows and the display stops working and again since then it hasn't worked. It's alive and perfectly normal in there, but I just don't know how to give it what it needs to bring it back that way.
Does anyone know anything to help me on this? It's quite frustrating when you see it work, then shut off. I can't use it at school to do my work anymore and it's such a nuisance.

You have a hardware problem. More than likely it is the cable that goes from the logic board to the display. It sounds like an internmitent short. Works sometimes not at other times.
The only way to fix a hardware problem is to replace the faulty piece of hardware and the only people that do that is either an Apple store or an Apple authorized repair center. That is unless you can diagnose the actual failed hardware part, find one from an Aftermarket Mac parts seller and replace the part yourself.

MacBook Pro 2013 doesn't turn on fully

Hey, sorry for the quick and crappy question (I have to go for a road trip in a few hours and need my computer), but my MacBook Pro doesn't fully turn on. I have a YouTube video of what it does. It does what's in the video, turns off, and then repeats when I power it back on.
http://youtu.be/a7idERS3kHU there's the video. All and any help would be appreciated.

Hmm, that's not good. There's a post like yours where they needed to boot off a different drive and we're then able to fix it. https://discussions.apple.com/thread/3487997
You can boot off another drive or mac and repair your MBP drive from there. This could be done by hooking it up to another mac in target disk mode or by creating a install USB stick.
Or if you had a backup you could erase and restore.
Or finally, if none above are possible then it might be easier to take it in to the apple store.

Macbook pro retina doesn't turn on for a day or two

Macbook Pro Retina 13-inch Late 2012
2.5GHz Intel Core i5
OS X Yosemite (10.10.2)
So this is a weird one... I recently purchased a used Macbook Pro Retina and the previous owner had upgraded the hard drive for a bigger size. My macbook worked great for a few days but then one night I closed it and the next day when I opened it, it would not turn on. I tried rebooting the battery (SHIFT+CONTROL+OPTION and POWER) then hitting power but NOTHING. At one point, I heard a clicking sound when I would leave the power button down. Then... two days later I push the power button just because and BAM! The screen comes on. (I didn't hear the start up sound, and it wasn't like it restarted.) It was as if the screen brightness was all the way down but then came back. (I kept trying to adjust that too before it turned on).
I don't understand!!! Two days later, same thing happened. Then again, it turned back on a day later.
The only thing I noticed that was weird was when I connected it to my tv with HDMI cable. The laptop screen would freeze and get distorted and I would have to force a restart (the black screen with the apple would appear and the loading bar as if I would updating the software).
I'm soooo confused and I don't want this to keep happening. I would appreciate any type of help or advice!!

My MacBook Pro screen doesn't turn on when I the open lid.

So I bought my 13inch MacBook Pro Retina two weeks ago. 70% of the time when opening the lid the screen will not turn on but my keyboard backlight will. I then have to either close the lid and open again or press the power to put the system to sleep and wake again. It seems the system is working fine just not the screen.
I have tried the SMC and PRAM reset which seemed to work for half of the day, now the problem is back.
Has anybody got a solution for this or are in fact experiencing the same problem?
Thanks

You've 90 days of free phone support from date of purchase and - at least - a one year warranty on the computer (free phone support and warranty for three years if you purchased AppleCare). The behavior that you're experiencing is not normal - if I were you, I would get on the phone to Apple and have them make you a 'genius bar' appointment.
Good luck,

When I open the MacBook Pro, display doesn't turn on!

I have a new MacBook Pro. It doesn't seem to wake from sleep. Also, when it is operating, it doesn't respond when I try and put it to sleep. Lastly, sometimes when I shut the computer, I notice that it will remain very warm for a long time in my bag, even though it isn't plugged in. These all seem very related.
Any Suggestions?
Thanks!
Tim

Welcome to Apple Discussions!
I also had some sleep problems with my new (in September) MBP running 10.4.10. Mostly a tendency to freeze if the display went to sleep, which does not seem to be the same problem that yours has. When I went to Leopard, all of these problems vanished.
Is yours asleep or frozen? If the sleep light is steady instead of pulsing, it may be frozen. And it should not freeze.
I have never had a problem with the MBP getting warm in my bag, but then, I always shut it down rather than put it to sleep. But I have heard of others getting warm. The MBP uses its aluminum skin to cool itself, and that doesn't work well in a bag. So I don't think it's good to put it in a bag asleep although I am sure others will disagree with this.
Since it's new and under warranty, you can always take these issues up with Apple.
Good luck!

My new Macbook Pro suddenly won't turn on!

I just got my new Macbook Pro 15" 2.66GHz and now it won't turn on. I was using it until it almost didn't have any battery left. Then I was away from it for a while and when I came back I couldn't make it work again. When the power cable is plugged in the little white light on the cover blinks and I can here a strange sound turning on and off again and again - sounding like the harddisk turning on and failing, turning on and failing... Now the power cable has been in the computer for a while but it's still like this and the lamp on the adapter is green - not orange, which it should be when it's charging. This is really bad since I have a lot of work on it, do you know anything? Please and thank you.

If the little light on the front of the MBP is still on, hold down the power button until it turns off and all signs of activity stop. Then reset the SMC:
http://support.apple.com/kb/HT3964
Reconnect the AC adapter. Does it begin charging now (orange light on the plug)? If so, let it charge for half an hour and then try starting it up again. If that works, it's ready to use normally.

Macbook Pro 2009 doesn't turn on without battery

Hi. I have a mbp mid 15" mid 2009 2.66. In time the battery bacame very low like 4% health, and now is completely dead or broken. When i check the battery status leds it shows full and when I try to turn on the computer (of course with AC power) it tries to turn on for 1 sec then it dies, even with AC plug. i hear the fans trying to spin for 1 sec or less, i hear the hdd sound and i see the standby led like it is trying to power on normally but It seems like it's trying to use the battery to power on. (Even when the battery was good, it would't turn on if it was 0%.. i would have to wait 10-20min or whatever to charge it to aprox20% or whatever).
I can't buy a new battery right now so I tried to turn it on without battery (I am sure the battery is completely dead and if I put a new battery it will work for sure) but why it doesn't turn on without battery?? I don't believe it needs battery to run on AC power. It's a SMC thing. What can i do to use the SMC and run the computer wihout battery? Now I'm using it with SMC bypass (keep pushing power for 10 sec and plug the ac chord) but with SMC bybass the fans run at max speed, no keyboard backlight no sensors and all that uses smc its not working. Is it safe to use it that way? (it's not running slower, i don't have performance issues).
I tried PRAM reset SMC reset, removing battery with AC on.. nothing works. It won't turn on without battery. Only with smc bybass.
It is something i can do? or buying a new battery is the only solution?
Thanks.

My Macbook Pro Retina doesn't turn on but charger led works

I haven't used my mac for a month but it use to work perfectly fine. I tried to use it but it wouldn't turn on. When i plug the magsafe connecter the led goes orange. But when i press the power button it doesn't turn on. i tried smc reset using left shift, control and option (and power button) while charging and not charging but it doesn't work. Please help.

IF the battery was completely discharged, give it some time on the charger before trying to start up. The amber LED means it is charging, give it an hour or so before trying again.

Mid 2008 Macbook Pro 15" doesn't turn on

Hi everyone,
I have come to these boards pretty much out of desperation.
My MBP died on me yesterday and I'm looking for ideas on how to fix it.
I guess I'm hoping I can find a solution other than having to replace the motherboard as I'm quite fond of my lil' old MBP and would rather keep that one instead of buying a new one.
I didn't have any noticeable problems up to now. Yesterday I closed the lid to put it to sleep, as I always do because I don't power it down very often. About an hour later I came back, opened the lid and nothing happened. I'm not sure if it was still running at this point. I tried clicking the trackpad, pressing a button, nothing happened.
I tried to power it up and nothing happened. It didn't start running, I couldn't hear the fans, nothing. (At this point, the power and battery were connected)
The odd thing is, it only makes an effort to start up when I keep pressing the power button. I can hear the fans whizzing and normal startup sounds, such as the disk drive (but not the signature "boing" sound). The screen stays black though. And after 10 seconds of this, the laptop powers down anyway, wether I hold the power button or not. Moreover, when I start it up like this, and release the power button after for like 4 seconds, it stops starting up immediately and the laptop falls silent.
I tried taking out the battery and disconnecting the power cord and holding the power button for 5 seconds or more. This didn't change anything.
I also opened it up and exchanged the hard drive and changed the RAM memory. Still no difference. I tried disconnecting the hard drive + RAM + disk drive. When I try to start it up that way, the computer just keeps beeping (which makes me hopeful that the problem might not be with the motherboard anyway? It doesn't start up but does keep beeping all the time until I take out the battery and disconnect the power cord)
I might also mention that I had the graphics card problems 2 or 3 years ago, which was aknowledged by Apple at the time and they replaced my motherboard for free at that time.
Any clues what I could try? Or should I just give up and get a new one?
Thanks in advance!

Try a SMC reset:

If no success, look at this comprehensive user tip for possible solutions:

If there are no results, then spend 50 Euros or get a new Mac. I am out of ammunition.
Ciao.

My MacBook Pro 2009 won't turn on. It suddenly won't charge and when it did I shut it down and now it won't turn back on. Charging shows green and the green little dots are showing on the side. I tried smc reset, command p r, what else?

A four year battery could be dead. I'd contact an Apple Service Center.

Macbook Pro suddenly turned off, not charging either.

My Macbook Pro suddenly turned off last night. I've tried all the troubleshoots listed in the user manual. Thought it was just batt low but it would not even charge, neither the battery sign located on the left side wouldn't show any sign/blink/color. Please help me, it's just 8-month old and Im not sure what could be the reason of this problem. PLEASE AND THANK YOU

Help!!! My Macbook Pro suddenly turns off

Towards the end of my work day, my Macbook Pro suddenly shut off. I thought I had accidently pressed the power button or something, and so I turned it back on. However, 10 minutes later it randomly shut off again. The power was at about 80%. I connected the laptop to charge, and I was able to use it perfectly with no problem. After about an hour, I unplugged it and it continued to turn off again.
I am currenly running Mac OS X Version 10.6.8. I have included the power status, to see if this might be of any help.
CAN SOMEBODY PLEASE HELP ME?
Thanks!
