Sep 21, 2007My friends iMac G5 just recently has been randomly shutting down. Does anyone know anything I can do to him fix his computer?
I checked [URL] and there seems to be issues with power on some models, but his serial number just misses the infected batch.
PowerPC :: IMac G5 Started Randomly Shutting Down When Not Used
Feb 5, 2008I looked into my issue a little but recently my IMac G5 started randomly shutting down when left unused for a bit but that seems to have stopped as far as I have noted. Now occasionally when it goes into sleep mode it will freeze on the black screen and the fan will go crazy. I plan on buying a MBP, if the update ever comes out, and then ill just completely wipe the IMac and give it to my parents, who still use the original I mac, G3 or something. I read a certain series of I Macs were having motherboard problems, W950 or something, but mine wasn't that serial code.

OS X V10.7 Lion :: Screen Randomly Shutting Off?
Jun 17, 2012So frustrated with this situation. It appears this is only happening since upgrading to Lion so that's why I've chose to post it in this forum. My screen has been shutting off randomly. And I've only been able to get it to happen when I use gestures on the trackpad. (I.E.: "App Expose, "Show desktop" or "Show all windows.) I say my screen because the HD is still spinning, the keyboard backlights are still on and the status light is still lit. I can't do anything but hard shutdown. I've tried adjusting the brightness, clicking, keyboard commands (force quit) and nothing does anything. I've been sending the crash report to Apple but I feel like that is pointless so I'm turning to the forum for a possible answer. I've inluded my specs below as well as a copy of the log that got sent to apple (in blue). I don't know if it will say anything to anyone but it's worth a shot. I don't think it's a screen cable issue cause I'm not moving or adjusting the screen when this is happening.

MacBook Pro :: Why Does It Randomly Keep Shutting Off
Dec 7, 2014I'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?

Aug 3, 2009I have a MAc Pro, Bought in January 09, pretty much stock except for an exta 500 gb drive and the Nvidia video card.
I have a strange problem, I will be using the computer and it will just shut down. Ie my LCD monitor shows the "RBG MODE" screen which it shows during a reboot or if turned on when computers off. My Intelli mouse explorer laser mouse turns off but if I click the laser turns on and off with each click and the power light on the tower is lit but nothing turns the machine off/on unless I hold it down till it reboots.
This has been happening since about the beginning of July, happened last week again every 10 minutes or so it would do this. Saw a post that said it's cause its too hot and its shutting down for safety, I have Istat and the temps at that time was 35 degrees celcius ambient and the processors when watching a dvd or somthing was around 40 degrees, I installed smc fan control and ramped up my fans and with them runing 1500 rpms the temperatures have been steady at around 32 ambient and 35-37 for the vaious sensors. Today the heat wave is over and istat says the ambient is 26, processors and drives are still 35-37 and it rebooted again.... is my machine running hot or is it somthing else.. I am at a loss. It is a Stat holiday here so I cant call my local repair place. Running OSX 10.5.7 any other info is available if needed.
MacBook Pro :: Shutting Down Randomly - How To Solve It
Feb 7, 2010So, for the last week or so I'm been experiencing very strange symptoms, which I think are probably all connected:
1) My MBP (running 10.5.8 bought in August 2008) has from time to time just been turning itself off. Like, I'm just working on something and then it suddenly turns off.
2) My mouse from time to time stops responding to input, sometimes the keyboard does the same thing
3) When I restart after 1 or 2 occurs, it doesn't work. The computer turns on, I get to the screen with the apple on it (there's a chime all of that), then it goes to a plain blue screen and just stays there - the log in box never comes up.
4) In what I think may be related, my computer seems to be running extremely "hot" right now. After just normal use, I'm reaching GPU temperatures as high as 75 degrees according to iStat and CPU temps around 70.
MacBook Pro :: Randomly Shutting Down For No Reason
Jul 3, 2012Macbook pro (older style non-unibody) running 10.6.8 has started randomly shutting down instantly for no reason. Sometimes only lasting 30 secs before just shutting off, sometimes up to 10 minutes. Happens when cool or hot, no apparent rhyme or reason. Tried resetting SMC, no difference. Ran software update, thought that had fixed it as it stopped happening for a day, then the problem started up again.

Feb 11, 2010My Macbook is 1.5 years old (13in, white, 2 GHz). About two weeks ago, it would randomly shut off. It would restart fine, but shut off sooner. Sometimes, it wouldn't even restart. Now, it's at the point where when I power it on, it rarely restarts past the white apple start-up screen.
My thought is that it is overheating. Are there any more ideas? What can I do to save my macbook?

MacBook Pro :: Keeps Randomly Freezing, Shutting Down, And Beeping
Apr 4, 2012I had been using it for about an hour without any problems when this started happening. Ever since, I've been consistently having these issues. It is a mid 2010 model. It also sometimes flashes weird glitchy images instead of booting up or starts flashing them while I am using it, and then shuts down. Here's a quick video of what I'm talking about (it was showing even crazier images before I started recording it)[URL]

MacBook Air :: Shutting Down Randomly While Listening To YouTube
May 7, 2012First of all, let me give you a rundown on everything I have done: I have reset SMC. I have reset PRAM. I have disabled Java in all browsers, and I have deleted Java. I have erased disk completely, taken it to the Apple store and have OS reinstalled. I have repaired the disk. I have repaired disk permissions, and I discovered Java had a value of 80, should be 0. (This caused me to disable most Java programs.) I have verified the disk and disk permissions.
After the restore, I have only reinstalled a few programs: (Upon reaching this problem again, I deleted some programs):
Opera Browser - Deleted, did not allow me to disable Java.
Caffeine - Deleted, not well known.
StarCraft II - By Blizzard Entertainment, too uptight to create this kind of problem.
Komodo Edit - Deleted
Skype
LogMeInHamachi - Deleted
Files:
A folder with some HTML and CSS and a few pictures - Deleted
A screenshot of my computer on my desktop.
I have no music in iTunes. Nothing. For example, right now, I am listening to YouTube and typing this. A message pops up with message: Are you sure you want to shut down: Sleep Restart Cancel Shutdown (Shutdown is blue).

Nov 1, 2009I have a ibook G4 that's been randomly shutting down. It started doing this maybe about a month ago but it's started getting really bad lately. At first it would shut down if I unplugged the adapter. Not every time I unplugged it, but probably about 50% of the time. When I press the battery button all of the green lights would light up. About half of the time it will start up again if I just hit the power button but the half of the time I have to reset the pRAM. Lately this same thing has been happening except when the computer is still plugged in. And when in say shutting down I mean essentially instantaneously. One second it's on and then the screen goes black and it makes that turning off noise. Not a chime, but like all the fans and hardware are coming to a stop.

May 13, 2012My Macbook pro is not charging. If I move the cord (specially at the Macbook charging port) it charges. But again if the cord is slightly disturbed then it doesn't charge.

Apple care (Genius) is far from my place.There is no visible physical damage on my mag charger. Could anyone suggest what I should do?

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.
