MacBook Pro :: Won't Turn On After Suddenly Shutting Down
Sep 2, 2014
I was working when both the charger light and computer went off suddenly. I did the same click sound it does when holding the power button to force it to shut off. Since then its dead to the point that when I connect the charger the little orange/green light doesn't turn on nor does the computer nor does the battery meter on the side of the computer. Battery was perfectly good holding charge and it was full.

I got my Macbook Pro only 6 months ago, and supposedly, it is a really strong and good computer: 2GHz Intel Core i7 with Version Mac OS X 10.6.8.
A couple of times a week the screen suddenly turns blue. I can't really figure out a pattern as to when it does it. Often, I'll be switching between word and a pdf and then it just suddenly turns blue and I can't use any bottons. I just recently discovered that if I simply close the Macbook and open it up again, then I'll get back to where I was before it turned blue. In this way, I can make the computer 'wake up' by closing and opening it once or twice. Also, I can force the computer to shut down by holding the switch-off botton down for a while.
However, something is obviosly wrong, and it is anoying and also, I would like to find out if it is a hardware problem before it's too late to get it fixed within the hardware-protection period of 1 year after purchase.
I just formatted the hard drive a couple of days ago and re-installed everything, but it still happens. Also, I tried to do the 'hold down option-command-R-P'-thing but it hasn't solved the problem.

my Macbook Pro is not powering up, Yesterday I connected a camera that has the USB cable with the little transformer. And the Computer suddenly turn off! It´s not working at all... I really don´t know what happened..These are some of the characteristics of the problem:
1) Not even the battery Light its on when I press the Power button.
2) Not even the Light in front of the Mac is on when I press the Power button.
3) There is not even a sound of the cooler fan or anything.
4) When I connect a the power cable the first 10 seconds the light of the cable is off... Then it appears a little "Orange intermittent" light but nothing more happens.

I keep having the screen turn blue and then suddenly go back to normal. It's a quick flash, totally random, repetitive during operation, no noises, and nothing else is interrupted. It does not restart, log off, or try to. Is it about to die?

I tried the "search" box before making this thread. Would like to know if the power supply from a 2008 MacPro work on a 2006 MacPro. If anyone has tried this? My 2006 MacPro shut down suddenly and would not turn on. I use an APC UPS plugged on a power surge outlet. The Mac technician who examined the unit suspected it might be the power supply but Apple may not have in stock the power supply for the Ist Gen MacPro.

I have a MacBook which has recently been shutting down when it feels like :/ this all started a week or two ago (well not the shut downs but other issues that I'll get too), basically the fan I think has been knocked as it is bumping the top or something as the whirring is getting loud and it sounds like every now and again it hits something
Also CPU usage seems to be averaging out at 20% for Safari and 100% for HD Video where as it used to be very small amount for Safari and 30 - 40% for HD.

I have a problem with my 17'' MBP unibody:
1) Bluetooth is ON:
I can't turn it off. The checkbox is inactive.
But I can turn it off, if I choose "Share my internet connection for other units". (I don't know, if this is the right text in english, because my OSX is in german)
2) Now Bluetooth is OFF:
But I can't turn it on, because the checkbox "ON" is inactive.
It turns only on, if I choose "New Unit"(?). Then there is a new window, that says, that this is only possible if Bluetooth turns on. If I say OK, bluetooth turns ON.
Back to 1)
What's the problem. Why is this f* checkbox for turning bluetooth on and off inactive?
This is not a hardware problem, because I can have stable bluetooth connections.
I did a smc and am pram reset. But it doesn't help.

I use Daylite and Daylite Server on my MBP connected to the net and sync my iPad running Daylite Touch through my 3G connection. It works great while I have my MBP running. I want to set up my MBP so that it will run without shutting down (screen blanked out). I just want to do this for a few days to see how it works out. If I like it I will get a Mac Mini to run as the server instead of the MBP.
The problem I am having is that no matter how I adjust the settings on the MBP, after awhile it shuts down Daylite and Daylite Server. Daylite Server shuts down and puts out an error message and everything just hangs there. I figure I must be doing something wrong in the settings but don't know what. I tried searching the forums, google, apple support, etc. but haven't found anything - of course I am probably searching all those wrong too.

When im playing a game in bootcamp, my computer just randomly turns off. I thought it might be from overheating, but I started using a cooling pad to try and help, and it shut down almost right away the next time I went to play. It happens occasionally when im running osx, but not nearly as often.

After I bought it, I noticed that the fan was making loud noises when I used it too long. I know it is normal for it to overheat after a long period of use but it doesn't just overheat, the fan starts making a weird grinding noise. I thought that it was just dirty and it wasn't affecting the way my computer was running, so I just ignored it.
It has been almost a year now since I first bought it used and the fan has gotten a lot quieter, but just starting last week I was watching a movie on Netflix and right in the middle of my movie, the computer just randomly shut off. I figured it was overheating. But, even after it had cooled down, I went back to watching my movie and within 10-15 minutes, it did it again!

I have a Macbook Pro that is a few years old. It's been fine until recently - it shuts off - poof - when I try to play certain games on Facebook, or watch a video on Facebook. I can watch videos fine on a site like YouTube. I thought perhaps it was the browser I was using (Firefox) but it's not. I ran disk Utility and that didn't . Software Update says I'm up to date. I'm running OS 10.4.11

I use my MBP (Unibody, 2.8Ghz, 4GB RAM, running 10.6) in clamshell mode connected to an Apple Cinema Display ... Been doing that for a year and a half now and never had any problems.Now, since a week or so, my MBP keeps shutting down randomly, probably due to heat issues.So I installed SMCFanControl and run it at max RPM. Still no help.My system reaches over 90?C before it shuts down.Now I disconnected my MBP from everything (ACD, speakers, external HD, iPhone dock, Ethernet cable) and when running on its own off battery power, the temperature has already dropped down to 60?C and it stopped shutting down.

My MacBook Pro 8,1 freezes with blue screen and indicator when I try to turn it off. I tried using Disc Utility and OnyX, but no result. In a service centre, they have done an inspection and told me that there are no hardware problems.

I just bought a 13 inch MBP yesterday. I know macbooks are supposed to sleep when the lid is closed by default. But a few times when I opened the lid, the computer had appeared to turn completely off. The indicator light on the front was steady when the lid was closed, not blinking like I believe it is supposed to be when sleeping.

I have a Macbook pro 2011 13" which I keeps shutting down constantly. I erase the macintosh hd drive as suggested, also did the ctr, command, option, p and r step and when i try to reinstall the mac os x snow leopard it goes through the process and gets as far as 3 minutes into installation and then shuts down. Even when I try to install the mac os x lion from the disc utilities screen it goes throu the same process and then shuts down and reboots. it constantly shuts down and reboots.

I am running the Software OS X 10.9.4 (13E28) and have a macbook air, 13 inch, mid 2012.
I am in no way an advanced user of this computer only used for browsing internet and some college work
Recently i have noticed a small niggling problem, that my mac is shutting down when left idle for a time, instead of going to sleep like it always used to do.
Now when i come back from being away i have to restart it up and at times have lost windows ive been working on.
I tried to alter some of the settings in the Power saving option but it doesnt have anything related to the shutting down of the computer. I used to be able to close the lid and it went to sleep but now i think its shutting the laptop down too.
Obviously the quick start up time on the mac, and the option to put it to sleep means this isnt a massive deal but i was just wondering how to fix?

I've had it for about 6 years now and always have to have it plugged in because the battery is swollen and won't fit for the lid to stay shut. Now recently it's been randomly shutting off and have to turn it on again. Is it dying or it simply not getting enough sleep?

over the past few weeks my blackbook has been shutting down more and more frequently from what I can only believe is overheating. I just checked my computer upon startup with SMC fan control - it starts up at about 70 C and at about 3500 RPM. Yet, after a few minutes, the fan immediately drops down to 1100 RPM or and fluctuates between 800-1400. I try to force the fans to spin with SMC Fan control, but nothing happens. I've looked all over the web and I can't find anything definitive. I know that macbooks tend to overheat. What can I do?

I'v just noticed, after installing iStat menus, two different CPU usage measurement graphs. Core 2 duo, so apparently one for each core or chipset, whatever . But the weird thing is, that sometimes, while watching movies, burning dvd etc. (sample "high usage" situation), when the CPU temp. goes around 60 celc. and fan spins at 6200 rpm, one of the "core graphs" shows nothing, like the core is shutting down (screen attached). It's annoying, because the whole system slows down, I can't do anything, and after like 5 mins it gets back to normal (after closing for example the movie). Any solution for this or should I just get used to it?
