MacBook Pro :: System Shutdowns Randomly / Temperature-related S.M.A.R.T. Failure
Feb 19, 2010
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.
Ive been experiencing multiple shut downs, particularly while streaming video from the internet. I think it may be overheating..anyone else have this problem? Running a MBP 2.16CD with snow leopard Also, I'd like to add I just experienced something weird. It was a shutdown, but it was like a shadow melting over the screen, then it said you must restart the computer in a few different languages. What's that about?
Does anyone know if there is a certain temperature that causes iMac's to shut down? I have been queuing up a number of movies in Handbrake and letting the iMac chomp away at them. For several months this was not an issue (this is a 2009 iMac 2.93 base model, no upgrades.) For the last week or two, I have come back to find the computer off a number of times.
Every time it has done it i was while Handbrake had the processor pegged at 100% for a long time. The 3 highest temps are usually the power supply, the Northbridge and the CPU and the highest I have seen them is right around 70C. Last night I did some messing around with that fan control program and got the fans to run higher while Handbrake was running.
I managed to keep all of the temps below 65C. I am going to leave it like this for a while and see if I have any more problems. I'm also going to try to cut back on the number I queue up at a time. I was setting up enough to keep it going for 12-14 hours. I don't actually think it was a time thing though as last night it shut down while my wife was using it and it was less than 2 hours after I started a batch.
Has anyone else had similar experiences? I see some people suggesting it could be caused by bad memory, but as mine only seems to happen with Handbrake at 100%, I'm thinking it's just heat.
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?
My Macbook Pro keeps a constant temperature of approximately 80-85 degrees Celsius with only the internet browser running. Is this too high? I have also talked about my computer shutting off on games that were not very graphic intensive like Torchlight.
What temperature is good for your macbook to run at. I'm usually always around 135-145 degrees. I have smc fan control, and i am running my fan at 3600rpm's please let me know what you think about the subject.
My first gen macbook is running with a CPU temp of 71 degrees celcius while running nothing. The mds and mdworker processes are taking up most of the processor and it wont change after quitting the processes or restarting or shutting down the computer.
Recently I bought a MacBook Pro 13", once I open it, it starts with 40C processor temperature, hitting 70 after sometime and stays there, and when I run an application it hits 80-90C? Is this normal! Whats the maximum temperature of my 2.53 processor!
I recently bought a MacBook Pro 15inch, the 2.66Ghz model;Nice laptop, but I'm worried about something: I play some games from time to time and I have been noticing that the CPU Temperature goes very High.My record is 92?C just moments ago while playing World of Warcraft.ou can see a screenie here: http://drp.ly/6gW9a (In this screenshot the Fans speed was about 2600rpm although under 90? they drop to 2000rpm)The laptop itself is not hot though, it's warm. (And I like it <3)
I'd like to uninstall SIMBL. The only plugin I've ever used is megazoomer, and it doesn't work for 64-bit applications, and I don't want to have to run them in 32-bit mode. I deleted the bundle from /Library/Application Support/SIMBL/Plugins, but aren't there any system-related files that need to be removed as well?
My primary MacBook is suddenly now powering up - Tried the power management reset....removing battery/power and attempting restart after 12 hours and so forth. Does this sound like Logic board? Is there a chance the HD data can be retrieved if it would be installed in another MacBook or...if Logic board is repaired?
I just installed the iStat Nano widget in my MBP 15" Core 2 Duo 2.53 GHz. Amongst other things, it displays the system temperature, which is currently at 32 Celsius. However, I do not know which is the appropriate temperature range for my system, so I cannot know which level should be an alert for me. Could someone inform me about the appropriate temp levels? Moreover, I have ordered and expect soon the new MBP 15" i7. Are the same temperature levels appropriate for all Mac machines, including my new MBP?
My 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 won't boot. Symptoms preceding failure included failure to open Firefox. When trying to cold boot I can get as far as the start-up sound, the Apple logo, and the spinning whieel (spins for a bit but not for very long) and then major failure. Not running Liom.
Info: imac 10.1, Mac OS X (10.6.2), also have macbook pro running os 10.5
I used SuperDuper to create a mirror image of my SSD boot drive on one of the partitions on the external drive. Thinking it wise to actually check to see if the partition would boot, I used System Preferences to point to the new boot drive and restarted the ol' 2008 8x2.8 Mac Pro.
All seemed well with the startup from the new boot device. But when I tried to go to System Preferences on this system, the app failed without ever initializing a window.
I noticed that iStat and Temperature Monitor report different temperatures for the same readings on my G5 Powermac Dual Processor System. For example as I am writing this Temperature Monitor is saying My CPU A is 46.8C and CPU B is 46.7C. In iStat it says CPU A is 55C and CPU B is 54C. Which is right!?
I apologists straight away if this have been covered recently, but i need to ask.I have MacBook with Intel Core Due Processor, 2 GB ram.What is the average temperature CPU temperature for standard usage ( I know that standard usage is very arbitrary, and by this I assume safari, iTunes and let say Pages to be the only major apps running ).I use iStat pro widget and according to it my CPU temperature is 55*C. Is this too high? Lately the fan has been turning on more recently almost without any apps running so I think that there might be some hardware problem. I ran HardwareTest it found nothing.
The macbook is 2 yrs old. Do i need to get it cleaned or is there something else I should be worrying about?
I have had several issues with the USB on my brand-new Core i5 macbook pro. It randomly disconnects USB devices. I've had the issue with multiple USB devices - same story with each one. Further, iTunes will only recognize my iPhone if it is in the port nearest the magsafe connector. The other port fails to recognize my iPhone entirely. Anyone else having a USB issue on their base 15" that was released today?
Furthermore, any suggestions of what to do about it? I'm having a hell of a time restoring my iPhone with this issue... And the Apple Store is over an hour away-I planned a special trip to buy this laptop.
I have just loaded the new operating system snow leapord on my Imac and now am having MAJOR problems with my Quickbooks 2009 for mac. Is anyone experiencing a high frequency of Quickbooks quitting during operations and getting a crash failure?
I have a 1 TB LaCie Big Disk Extreme 2 that is actually made up of 2 500GB drives. It failed on me. I have most of it backed up but there are a few things I would like to recover. I tested another power cord and it didn't work. So I talked to a few people and they said that if I bought a new seagate controller board that matches my 500GB drives identically I would be able to get the data off one drive at a time. There is some good and some bad. When I tested the new controller board on each drive (one at a time only because I only have one new controller board) they both started up normally! Success I thought.. but no.. Both Leopard and XP said "drive needs to be formatted" or "initialized".
when power pressed to boot, it will go into boot, but then the screen starts flickering from dim to bright a clicking sound is heard, the power cord on the side changes from dark to light amber. the screen then goes to black. some times am able to get to log in then it just goes black.- More information- my harddrive had been making erratic noises for about... 3-4 months. some loud clicking... in thinking that the hd failed i bought a 160gb WD Scoirpio blue IDE drive... These problems still persist. even when i option to start up with my external drive, which i have mirrored my hard drive. it will boot up for the external then this clicking noise as noted above.
My IMac crashes sometimes very suddenly, like in a power failure. It doesn't force quit or shut down, it just goes like somebody pulled the plug. It's usually possible to start it up again after 30minutes or an hour. The plug and lead seem to be fine. I tested it on another mac. The obvious suspicion would be overheating, but how can that be caused so suddenly (and how can I fix it)? It's an IMac Intel core duo, 20", 2 ghz, 2gb ram from 2006. I'm running Mac OS X (10.4.11) 2006.
It looks like the hard disk in my 1.5 year old iMac (24" 3.06 C2D, running 10.6) suddenly failed today. I woke the mac up from sleep and pretty much immediately I got a spinning beach ball. The system was totally unresponsive so I did a hard reset. Unfortunately the blinking "?" folder came up on the gray screen, instead of the familiar Apple logo. Booted off the OS X disk and ran Disk Utility. The hard disk comes up as "media" and unrecognized by the system. So no First aid or formatting possible. I'm guessing the hard disk has given up but before purchasing a new one I want to rule out anything more serious like motherboard issues.
I have a 2009 8 cores 2.66Ghz Mac Pro with 16GB RAM and ATI Radeon HD 4870. It keeps waking up randomly from sleep. I have tried quitting all applications before sleeping, but it still woke up from sleep by itself. Anyone has nay idea why it kept waking up randomly?
However Safari is causing all kinds of hangs restarts kernal panics overheating with my machine and yet if I use google chrome for the exact same web sites these same problems are not present. I much prefer to be able to keep using safari and I realise that I haev not got the most up to date software since Lion is not supported on my machine but it is as up todate as snow leaopard allows.
I also realize that a more than 5 year old machine is doing very well especially since it is rarely off. It has outlasted 2 timecapsules and countless airport express but the anomyly between 2 browsers is weird. I doubt this has a solution but maybe the odd apple tech who read this might find it a challenge to know why one browser causes heart issues but another doesn't.
My mid-2014 15" Macbook Pro randomly "loses" its retina display at the top menu (becomes pixel-y), where the battery, sound, and wifi logos are (on the top right side of the screen). A restart fixes the issue, but I want to know if this is an issue that can be fixed?
I just received my 3rd replacement mac pro, the second one (same spec, apple replaced it for me) is here too. I'm trying to get the 'new' one up and running. They are both identical spec - stock Octo 2.8, with 8800GT, 500GB HD, and Airport.
Anyway, I bought a 750gb Samsung F1 on the 'old' mac pro and installed my OS and all my audio software and plugins on there. The 500GB drive holds only the audio data (no OS). Is it OK to just remove one boot drive from the 'old' mac pro, and put it in the new one? The are both the same spec machines...
The reason i ask is because i am getting very scary and random SHUTDOWNS on the new mac pro, all of a sudden - it will turn off, then briefly (for half a second) the fans will spin again, then it will die. It is as if something is tripping the power off, or messing with it at least. It's done it several times now. The first time i was doing a time machine backup, came back to the computer an hour later, and it was off completely. It wouldn't start for a while, then all of a sudden, it did on its own, a couple of seconds after i tried pressing the switch.
I tried to run the apple diagnostic test, and shut down after a minute or so. So i took out the stock 500GB hard drive (only the 750GB left in it now) and i'm running it again. We'll see what the results are. But anyway, has anyone done this? It should be ok to take the drive out and put it back in, right?
recently my mac pro has been randomly freezing then all 3 of my screens go blue for 5 seconds, then everything is back to normal. This happened 2 months ago, and eventually my graphic card died. I dont know whats causing this, I have tried different cards so i no its not hardware. Anyone have this happen? Any fixes?
