My 15" MacBook Pro has been randomly shutting down. I ran Apple Hardware Tools, but it found nothing. So, I ran TechTool Pro 5.0.6 and discovered a SMART drive failure. On the 'Temperature Changes' test, the black indicator is all the way to the right. What does this mean? What do I need to do?
View 2 RepliesI 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.
My 2.33GHz C2D MacBook Pro running 10.6.3 has suddenly decided it doesn't have an optical drive installed!
If I put a CD or DVD in the drive it will pull it in, spin but fail to recognise the disc. It is impossible to eject the inserted disc by any means - except by using a piece of cardboard to stop it spinning after a restart. I have tried data, audio and video CDs/DVDs.
System Profiler says I only have a hard drive attached to Serial-ATA and have no Disc Burning devices installed.
Has the optical drive failed? If so why does it still spin up if the computer doesn't know the drive is there? Does the fault lie elsewhere?
I've been having troubles with safari shutting down randomly. I went to [URL] to try and reinstall safari. But it won't let me do this because it says this update requires mac os x 10.5.8. or newer. The thing is I have 10.6.1. What should I do now?

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?

a close friend has a 20' iMac g5. the Computer now shuts downs sporadically and she says it gets a lot hotter any idea what's wrong?
View 5 Replies View RelatedI 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.
So, 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.

So 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.
View 5 Replies View RelatedMacbook 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.

I'm using iGetter version 2.8 and it's great. Downloads are quick, but I have one concern about the program. It randomly shuts down every 5-10 mins or so. The downloads aren't finished downloading and iGetter shuts down.
View 1 Replies View RelatedMy 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.
I 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.
View 2 Replies View RelatedMy 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?
When my Macbook pro is not plugged in, and i try to watch videos, it shuts down like it dies, even if it says the battery is 90%. Is it a battery issue? Or some other type of issue? Bought it in late 2008..

I 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]

First 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.

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).

I 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.
Recently got a week 8 x4 i7 27" iMac. When running Windows 7 x64, sometimes randomly the screen will fill with pink squares and just freeze and shutdown. It looks like a graphics problem but I could be wrong.

I have an original MacBook Pro 15" (A1150) that randomly shuts down. Seems to be running very hot. I've already had to replace a bulging battery, and TechTool Pro has indicated a temperature-related S.M.A.R.T. failure with the HD.
If I downgrade the HD from 7200 RPM to 5400 RPM, will that help with the heat issues? Any other heat-related fixes? I know the 13" MacBook Pro suffered a random shutdown syndrome, but I didn't know if the 15" was affected too.
I was listening to music on my macbook with headphones one night and once I unplugged them my sound stopped working. There is no red light coming out of the headphone jack and when I go to the sound settings it says there are no output controls. I don't know what to do because everyone says theirs has a red light but mine doesn't.

My 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. The problem got worse as my Mac randomly shuts down (especially when I remove the mag at the Macbook charging port). I dono what to do. 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?

We have i-Mac 20" with built in i-sight Power PC, one of last ones I think before the intel. We have had a few problems before with it powering down and going to sleep. Used to hoover dust out and that seemed to fix it.
Now it won't start at all. I have tried all the PRAM and various commands to re set various things but none of these work. We had a wireless keyboard and I have just tried a wired one but I do not think either are connecting as the tab key light does not come on, which it does when I tested the wired on on my lap top.
When it died it crashed with a cd in drive. I have removed this and replaced it with the mac install disk to try and run the disk check but the optical drive is not starting at all either.
All that happens on start up is the sleep light comes on, then after a few moments fan starts to whirl. I can't hear the hard drive - have tried to rock hard drive to get it to spin but nothing.
Just wondering whether worth trying to replace optical drive or is this being controlled by hard drive - hence its not working nor hard drive. is there any way to recover data if it is the hard drive that is dead? anything else I can try and replace to fix it? could I use an external optical drive connected via USB to start?
I have tried to firewire but not joy their either!
