MacBook :: Shutting Down Randomly - How To Prevent From Shutting Down
Mar 23, 2010I 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.

Aug 25, 2009I have a fairly new Mac about 1.5 years old. Recently I am having an issue with it shutting down periodicly for no apparent reason and then it starts back up> I have noticed it does do this by bumping the desk or hitting the screen but it is only every so often and can't duplicate it by trying these things.
View 5 Replies View RelatedMacBook Pro :: How To Keep MBP From Shutting Down
Aug 30, 2010I 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.
OS X :: Mac Keeps Shutting Down While Playing WoW?
Dec 23, 2008About 10-15mins after starting a WoW session in 10.5.6 on a Mac Pro, the screen goes into powersave mode, and cannot be returned. This is leaving me with no alternative but to hard reboot!
I can hear the fans going mad as I'm playing, so wonder if it's a heat issue. If so, what to do about it?
Can anyone suggest:
a) How to break out of screen power save without hard rebooting?
b) What the issue may be and how to investigate/resolve it?
OS X :: Mac 10.5.6 Shutting Down Spontaneously?
Feb 13, 2009My mac os x 10.5.6, (2.8 Ghz Intel Core Duo, 2GB 800MHz DDR2 SDRAM) keeps shutting itself down spontaneously - no error message occurs before or after it shuts down, and when i press the power button on my mac i get no response.
I have to turn it off at the power point and turn it on again.
I have a power surge board and only my mac is plugged into it so i'm pretty sure it's not a surge problem.
It seems to mainly happen when the screen saver comes on, and i have checked all of my system preferences and i havn't selected to turn off hard disk's at any time etc. I have no idea why it's doing any of this!
MacBook Pro :: It Keeps Shutting Off
Mar 5, 2012When 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.

MacBook :: It Is Shutting Off Out Of No Where
Apr 9, 2012After 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!

Intel Mac :: Why Is It Shutting Down By Itself
Apr 10, 2012I have a late 2010 27in iMac and it has shut down randomly by itself 4 times in the last month or so, including twice in the last couple of days. I have 16G of RAM and am only using up to 8G ever. Just to be clear, it shuts down and does not restart automatically. I never have the screen brightness higher than half so I don't believe I am overheating it? I really want to know why this keeps happening.

Jun 20, 2012When I woke up this morning, I went to use my new Mac Mini. For some reason, it will appear on the monitor for about five seconds, and then nothing will show on the monitor at all. Attempting to restart the Mac Mini only finds it doing the same thing.

IMac PPC :: G5 Keeps Shutting Down
Jul 1, 2012Recently a email link was clicked on and since then my wife has been having issues with her G5 shutting down. Sometimes the box will not completely boot at all and others it will boot up for a moment and then shut itself off.
I have looked for teh Flashback Trojan and appear to be clean. If i boot the box in safe mode when booted in safe mode all seems okay. I have also recently reset the PRAM and have had the machine up for a few minutes and it has not shut down yet.

Windows On Mac :: Safe To Keep Shutting Down?
Sep 21, 2010Having successfully installed Windows XP via Boot Camp on my new iMac and with everything up & running I am wondering what is really best for my iMac? From what I understand, when using OSX, you should never keep shutting it down all the time (unless you're going to be away from it for a while). It's best to put your Mac to sleep each night and restart the machine once a week. So what about Windows?
Having used a PC all my life, I'm very used to just shutting the computer down everytime when I have finished what I've needed to do and booting it back up when required. I'm going to be using Windows extensively for the next year on the Mac, so should I put it on Stand-by or Hibernate each time I'm finished? Or is it safe to keep shutting it down? (Note: I have the SSD + HDD option installed. I assume if I keep shutting it down, the performance of the SSD will degrade far quicker?)

PowerPC :: IBook G4 Keeps Shutting Down?
Nov 22, 2010I had my iBook G4 a few years ago, and since I was about eleven when I had it, I'm not sure I always took the best care of it, but it's always worked pretty much fine up until about a week ago. It's started shutting down randomly. It also sometimes randomly goes to sleep in the middle of things. In particular, it doesn't seem to like starting up, or the internet, especially if I'm on youtube. I've tried a PMU reset, as it worked once before when my laptop wouldn't start up, but it hasn't worked properly. It's worked from anywhere from a minute from the time I start up again, to about a day or two at most, but it always seems to shut down again.
I really don't know what else to do with it... and I don't understand how computers work at all.
PowerPC :: Mac G5 Shutting Down - Overheating?
Nov 27, 2010I've got an early 2005 model Power Mac G5. Bought it from a hospital and it's really clean inside. Lately it's been shutting down spontaneously without warning. I thought it might be an issue with overheating, but I'm not that familiar with normal heat levels for a CPU. I installed iStat nano and checked the temperatures. I took a screen shot of the widget. Temperatures are in Fahrenheit. Can anyone tell me if I'm on the right track? What do I need to do to solve this problem?

Feb 2, 2009I have a refurbished iMac G5 that randomly just shuts off. It makes a little "zzzttt" sound, like something is short circuiting and then dies. Sometimes I can power it right back on and sometimes I have to unplug it and wait a few hours before it will come back on. While it's running, there are no issues. It functions beautifully. Anyone else had this type of problem or can you suggest a solution? Here's the info on it:

OS X :: New IMac 20" Not Shutting Down
Feb 4, 2009I've learned quite a bit from this site in recent weeks as I found it following my purchase of a 20" iMac (2.66 GHz) a month ago. I've got a question for the group and I'm quite certain it's a stupid one so please be gentle. As I do every night, last night I put my iMac to sleep at around 11:15 pm before going to bed. Upon awaking this morning I couldn't get it to wake up. Hitting keys on the keyboard didn't do it, nor did moving the mouse around. I'm not sure if this is important but both my keyboard and mouse are wireless. Power to the other things on my desk was still on so it wasn't a power problem.
Anyway, I hit the power button on the back to see if it had simply shut itself off and nothing happened. I hit it again. still nothing. Finally, hitting it a third time did the trick and the computer roared to life and came on normally. It had never done this before. It had always immediately awakened in the morning upon hitting a button on the keyboard. First, is this common for an iMac to shut itself down? Second, why would the power button be unresponsive? Finally, if the machine had actually not been off (which I doubt very seriously) did I do a big "no no" by hitting the power button to turn it off/on?
OS X :: Shutting Down And Force Quitting
May 14, 2009Having these main problems (which I'm sure many have witnessed using Leopard):
(I have a desktop imac (intel core duo 2.66).)
1 The machine often refuses to shut down (or restart) and I get that black veil slide down the screen following the "you need to restart your computer..." message
2. The machine refuses to shut down and just stays on the desktop image with the black spinning wheel spinning endlessly.
3. I'm getting problems with applications refusing to quit (even when using opt-cmd-escape) . even when the computer "acknowledges" that the ap has quit, the icon is still active in the dock underneath.
MacBook Pro :: Shutting Off By Itself - How To Repair
Aug 25, 2009I 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

Sep 12, 2009when i went to shut down my imac the apple menu wouldn't show, it was just a white box, i clicked hide + show finder for some reason which brought back the full menu but it went away again. i restarted finder but now when i click shut down nothing happens. im having a panic attack, i really need help, im scared to shut down now because something similar happened about a year ago and my hard drive got wiped. i just don't know what to do, im not sure i have everything backed up, either. im running tiger, but that probably doesn't matter.
i repaired disk permissions, its still not shutting down and finder is persistently unresponsive after re-launching. i verified my disk and it said 'volume bit map needs minor repair', 'invalid volume free block count' and that machintosh HD needs repair.

View 1 Replies View RelatedOS X :: Power Cord Shutting Off?
Dec 5, 2009I just started playing WOW a few days ago - now I am thoroughly addicted but today after two long sessions (about 2 or 3 hours each) the power cord on my Macbook (bought in July last year- not the aluminum one) quit charging the battery.
The first time the computer simply shut down, and I noticed the mag cord light wasn't on so I figured I had an outlet problem, switched outlets and voila light came back on. The comp started back up and I saw the battery was at zero so just figured the outlet didn't work and the battery drained out without me noticing.
Second time with the different outlet I realized immediately as I had been watching the mag cord light, light went off, now I know something is up with the cord. I unplugged it for a few minutes and it worked again. Is this some sort of auto shut off for the power cord? The brick itself is pretty hot (nothing too crazy- not even close to being too hot to touch), the magnet part where it connects to the computer is not hot at all, the processor isn't very hot (about 60 C) and I can comfortably rest the comp on my lap.

Mac Pro :: Computer Restarts Instead Of Shutting Down
Apr 7, 2010For the last few months, my MP has had a strange quirk. When I select Shutdown, the computer restarts instead. Then, at the login screen, I select shutdown and it will then turn off. I've tried disconnecting all USB and Firewire connections (except keyboard and mouse) with the same results. It does seem to be time related. For example, if I start up the computer, get to the desktop and then shutdown, it turns off no problem. However, after its been running for a bit it will do the restart thing instead.

Jun 6, 2010I 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.
