Intel Mac :: It Shuts Down Unexpectedly?

Apr 4, 2012

Three times today, my iMac has shut down while working. This has never happened before. Could it be related to the external backup drive, a G Drive Mini, pulling too much power?

iMac, Mac OS X (10.7.3)

MacBook Pro :: Shuts Off Unexpectedly

Jun 4, 2014

As of a few days ago my MacBook Pro has been acting oddly. When I shut the clamshell and reopen it again a few minutes (or hours) later it's hot and makes sounds as if it is working hard at something but the display will not turn on. I usually end up turning it off anf then on again via the power button. I have a wireless keyboard attached due to damage to the laptop's own keyboard, but use the laptop's power button (which still functions). I've reattached, and reset, the keyboard a few times in case that was the problem but had no luck. It doesn't hinder my usage of the computer once it's on again but it is strange.

Hardware :: Computer Shuts Off Unexpectedly?

Jul 29, 2010

I have a strange problem with my late-2008/early-2009 MBP. In the last couple of days, I have been using it and the screen goes black suddenly. It happened once for just a few seconds and then recovered, but today it completely shut off-- even though the battery was mostly charged (and I had received no warnings)-- so I had to reboot.

A few possibly relevant facts about this computer and this incident:

1) I've had it over a year and never had this problem before.

2) I had the logic board replaced recently because of an issue with sleep mode. This problem never appeared before the logic board was replaced (although this may be a coincidence).

3) Both times the problem happened this week, the computer was running on battery power.

4) Earlier this week (before the incident), I got a little warning to "Check battery" or something similar. The warning went away, though. Maybe this is a faulty battery issue?

5) When the computer completely shut off, it was also running a Time Machine backup. I noticed that TM has been having trouble today-- giving warnings about errors. Not sure if this could be related.

PowerPC :: G4 Turns Itself Off / Shuts Down Unexpectedly

Sep 23, 2008

I've a MDD G4 dual 1.0 along with the wide acrylic-bezel 20" Mac monitor with the light in the lower right corner. Yep, it's starting to look ancient. But I still have much use for it EXCEPT that it has a very nasty habit of turning itself off catastropically in mid-thought, as it were. Oddly, this behavior comes and goes in spurts. it will hit hard for a couple of weeks then a couple of months will pass with relative peace and stability. Then, back to the crisis.

Sometimes I get a warning from that power-on light in the bezel -- it might flash brighter for an instant, then within a few seconds the whole system loses power just as if I'd turned off my power strip. Other times, it pops in and out of sleep mode for several cycles, but usually this ends the same, with no power at all. Odder still, the machine has a tendency to turn itself on unaided. This can happen even after a controlled shutdown. It turns on, acts normal for 20 minutes, then maybe goes to sleep and wakes up a couple of times, then crashes. No intervention at all on my part at any time. This is not a software shutdown of any controlled variety. Anyone know what's happening? I can't tell you how much gnashing my teeth have endured.

MacBook :: Doesn't Indicate Low Battery - Shuts Down Unexpectedly

Mar 25, 2010

I own the first 'remolded' revision of the Macbook released in '08 (5,1), and have had it for over a year now. Recently though, after 10 or so minutes running off just battery power (fully charged), it shuts down unexpectedly. It doesn't say the battery is low, or near low, it just shuts down. It's really annoying, I have to use the charger wherever I go. I really need my laptop so I don't really want to take it to an Apple Store and have to wait a week to get it fixed, unless it's really necessary. My software is up to date. Any ideas on what my problem is/how to fix it?

I have Western Digital My Book Pro II 2TB hard drive connected through FireWire 800 or 400 cable. The problem is that it shuts itself off unexpectedly all the time. Sometimes right after I turn it on, sometimes after 30 minutes. After turning it back everything seems to be fine, no loss of data. Anyone else experienced the same problem and can suggest how to fix it?

MacBook :: New Unibody Shuts Down Unexpectedly When TOUCH The Power Cable

Mar 14, 2010

I got my macbook during November of 2009 but two weeks ago it started shutting down by itself once I touch the magsafe of the macbook or remove the magsafe. All it needs is a simple touch and it shuts down. When it does shut down, the light indicator doesn't come on anymore. I have to keep removing the magsafe, and plugging it back in like 20 times until it starts charging again. So now I just let it fully charge every time I use it since any sudden movement will cause it to shut down. I will be making an appointment next week at the apple store because I had no time to go these past 2 weeks. I never dropped it and take good care of it. I am just wondering what might be the cause of this? I hope they do not take weeks to fix the mac since I have a lot of homework to do

MacBook Pro :: Startup Screen With Apple Logo And Grey Loading Bar Then Unexpectedly Shuts Down

Jun 26, 2014

I have a MacBook Pro from 2010 I believe with iOS Maverick installed. (MacKeeper is also on there, which I just found out is apparently malware) 

So three days ago I was watching Netflix, the image froze, but the audio kept going. Figured my internet was slow, so I waited a little, nothing happened. pressed escape to leave the full screen mode, but nothing happened. None of the keys would do anything, not even the sound or brightness keys. So I did a force shut down by holding down the power button. 

I waited a little, then decided to turn it back on. Start up sound played, white screen with grey apple logo and loading gear appeared together with a grey loading bar. I figured that this meant it had to repair something. But after about a minute or two it just went to a black screen/ shut down. I left it off for a day, tried it again, same thing. Next day I tried booting it up while holding the shift key to do the safe boot (I knew it wouldn't work since I already had the grey loading bar anyways), same thing happened.

MacBook :: Shuts Down Unexpectedly - Screen "fizzling" When Using Thumb Drive

Feb 17, 2009

Well just recently my MacBook (bought 2/17/2007) started shutting down by itself. Seems to happen after long use (3hrs) and when it starts to get hot. Also noticed screen doin a "fizzle" when using a thumb drive. Anyway went to Apple and dropped it off. They said they will run some stress tests on it and get back to me. I know there are a few things out there about this but wondering if any of you have experienced this recently or at all?

No warranty either. So if it is a logic board issue not sure... or if its a heat sink issue? Not sure what that entails to get it repaired. I was not expecting them to take the MacBook right then and there so i was sorta concerned as it has everything but... want to get it figured out.

IMac (Intel) :: Shuts Down During Load Up Screen

Aug 24, 2014

I just got home and I realized the power was out. I bought this iMac literally like two months ago (I actually bought one two months ago but it wouldn't even turn on so they gave me a new one) It was working perfectly fine, and I was writing a report. I left the computer on and left the house only to return hours later with the power out, and when I turn it on it shows the start up screen with the Apple Logo, the little progress circle, and a progress bar that fills up to the end everytime but once it fills up to the end it stays there for a few minutes then the computer shuts off.

Intel Mac :: Beachball Starts Up But Then Quickly Shuts Back Down?

Jun 27, 2012

I can turn on my mac, the beach ball starts spinning and stays spinning for awhile, finally starts up but then quickly shuts back down? I have never encountered this type of problem with my desktop before!  I have checked all the power supplies and reset the powercord,  I unplugged the computer and tried to reboot it to no avail.  Does anyone know how to do the type of reboot where you hold down the power button and two keys (?) wait for the 2nd chime then let go of the keys?  I believe that is how it's done.

iMac, Mac OS X (10.7.1), operating system- not 100% sure?

After some of the latest upgrades in OS X Lion when computer goes into sleep mode some connections doesn't work properly. Web Server, SSH, mail server (if any) work fine but it is impossible to remote control the computer via VNC. When trying to connect to the computer once in sleep mode with VNC viewer or similar and after the user and password submmision you get the "The connection closed unexpectedly" error and it's only possible to remotely connect to the computer when manually wake up the machine, making useless the remote control service.

Intel Mac :: Programs Quitting Unexpectedly Or Will Not Open

Mar 29, 2012

This week I have several programs that are quitting unexpectedly, or will not open all of a sudden. Photoshop CS, office 2004, and even the Appleworks programs. They all refuse to open. I uninstalled PS and the office products, and then tried to reinstall and couldn't even do that from the install disk. I did do a disk repair scan, but it said there was nothing wrong with the disk.And I'm getting some SymSecondary launch(whatever that is) failure as well.
