My dual 1.8 ghz G5 intermittently shuts down

I just purchased a second hand dual 1.8 ghz G5 tower that shut down on me a week ago. I opened it up, pulled out the fan assembly and hard rive, put back in and then it ran fine for about a week. Today it shut down again and every time I would try to restart it I would get the chime...the Apple logo would briefly appear, then shutdown again.
I tried resetting the motherboard PMU (is it). Managed to boot from the Hardware Test CD and ran the short test...everything ran fine then same shutdown problem when trying a reboot.
Does this sound like any problem that might be inherent to these models?
Any help much appreciated ...then it's a trip to the dealer....sigh

Dave Highet-
I don't know if this problem is inherent, but there are a couple of things that can cause it to shut down right away. Usually that is the power supply or the mother board. Both can be fairly expensive to fix.
If you have any recourse at all with the seller I would suggest taking that path and get it replaced if possible. This machine won't fix itself and the problem won't go away until it is fixed.

Dual 2.3 GHz G5 suddenly shutting down

We have a Dual 2.3 GHz G5 (production week 10/29/05, Power PPC 970 v.3.0, with 2.5 GHz RAM), running OS 10.4.8. This machine has started to suddenly shut down - like someone pulled the plug with no warning.
After turning itself off like that, we need to wait around 20 minutes before it'll start up again and keep running. Once it has shut itself off, we cannot get to the logon screen without it shutting off suddenly again. After letting it cool down for 20 minutes, it'll run again. So it seems to be heat related in some way.
I've run Temperature Monitor and iStat, and everything looks OK. Of course TechTool Deluxe didn't find anything (does it ever?).
The machine will run for 2-3 hours under load just fine, but will suddenly click and shut off at some point - even when not under a load.
I've checked the System logs and Console logs and can see nothing, except once the system log reported "ApplePMU::PMU forced shutdown, cause = -122"
The other times there was no log entry, like it shut down too fast for the log to be written.
Is the power supply going bad? Is there a temperature sensor which is too sensitive?
We'd appreciate any help or suggestions.

o maybe there is something RAM related, but I can't
imagine that RAM would shut the machine completely
off. Can it?
I believe the problem is thermal related. You may have a processor acting up. Try running Hardware Monitor once, and see what your internal temps are running.

Intermittent Shut Down Syndrome Redux 2

The old redux thread was locked, probably because it became too large. This is an updated redux to replace the old one.
MacBook Intermittent Shut Down
Redux 2 (Updated Oct 13, 2006)
Guy Kuo
Do a google search for "macbook random shutdown" and you will find many people with similar problems reporting on various forums. Most frequently, the MacBook operates normally for several weeks or months, but mysteriously begins intermittently shutting off suddenly. The shutdowns are not accompanied by kernel panics, but instead the machine simply goes black and the machine is off. Initially, the cause of this problem was not known and early repairs of the main logic board and heat sink did not incorporate the changes made after the cause of the problem was discovered. Numerous attempts at user, ad hoc, solutions have been posted, but the only definitive and permanent solution requires repair by Apple.
The problem as difficult to characterize because its symptoms mimic more common causes of system failure (bad RAM, improperly seated RAM, improperly seated hard drive, bad software install, bad battery, bad AC adapter, corrupted PRAM, corrupted NVRAM) which ALL must be ruled out before making the sudden shutdown diagnosis. The problem's intermittent nature means it may not be possible to reproduce on demand.
At present, this problem is being addressed by Apple and affects at least serial number range 4H617-4H635. MacBooks produced after that date should have an updated heat sink assembly which does not have that problem. The problem seems to have two root causes.
1. Two heat sensor wires in contact with the heat sink can melt and once that occurs, intermittent shorting of the wires causes the machine to sense an emergent temperature problem and the system performs an immediate power down.
2. Also, as described in a MacTalk Australia posting ..... 2 small connectors that bake under the enclosed heat on the Macbook (the Mac book Pro has more space and 2 fans) these connects then loose contact with their pins.... Once contact is lost, the machine does an emergency power down
The common thread is that heat in the original heat sink and thermal sensor design eventually may cause the problem to occur. Once contact or insulation problems begin, the machine can begin suddenly shutting down while cold or hot. Until sufficient heat is built up, the MacBook operates without any issues. It is possible for an early MacBook to operate normally for months before heat causes the problem to occur. Indeed it is possible a machine may never exhibit this problem despite having this weakness in its components. None the less, the early MacBooks have a heat sink and thermal sensor wiring harness that is inherently prone to deterioration. Because the risk of deterioration increases over time, it is reasonable to expect more early MacBooks to develop intermittent shutdown problems as time passes.
There are some early reports that even a heat sink assembly replacement repair does not always solve the issue. In such cases, a logic board replacement may also be necessary, but at this point, heat sink assembly replacement should solve the identified problem unless the MLB was also somehow damaged.
The current count of affected MacBooks has not been disclosed, but well over 1,000 machines have been reported on-line independent of Apple. The actual number of early MacBooks which will eventually be affected may be significantly larger even if one discounts the tendency of the web to amplify negative news.
Because heat is the root cause of the problem, two camps have appeared regarding how to deal with this issue. This author believes that the MacBooks should be allowed to warm to full operating temperature by running some high CPU usage tasks (with normal circulation around the case) for several hours and then seeing over the next few days if the problem occurs. The rationale is reveal any tendency for the problem while the MacBook is within warranty and before any critical usage. The other camp believes that the MacBook should only be used lightly and never allowed to get warm enough to induces the problem. The reader is left to choose their own course.
Only a fraction of shutdowns are due to this particular fault. A large number of other reasons must be ruled out before a MacBook owner should become convinced their machine is one which suffers this problem. Bad RAM, poorly seated RAM, improperly installed hard drive, corrupted OS, corrupted plists, bad batteries, bad chargers, corrupted PMU, and corrupted NVRAM all need to be ruled out first. During your call to Apple care you may be asked to perform checks to rule out the above list. Once a diagnosis of intermittent shut down is made, repair can take days to weeks depending on availability of parts and whether additional components beyond the heat sink assembly needs to be repaired. Once repaired, the MacBook is less likely to redevelop the problem, but as of this date, long term usage of several months has not had time to happen.
It is the hope of this writer that Apple will continue to assist its customers with this hardware "defect." So many first time Apple owners could be lost forever if this is not addressed openly and aggressively.

Are you sure RSD is the problem? Then, first, be sure you have downloaded all the updates. The smc update (late October) stopped RSD for many people. If you're updated, then you may need a new heatsink. That's what stopped it for me. I had it replaced at an authorized repair center while I waited - only took a couple of hours. You are still under warranty, so repair will be free if RSD is indeed the problem. You can look on these apple pages for the nearest Apple Store or authorized repair center.
In the meantime, I found it very helpful to hold down the on button for 5 seconds when I restarted the macbook. That kept the processor speed down to 1.0 gH, and for some reason, for me and for some other users, RSD never happened while in that mode.
Let us know how it goes!

MacBook Pro Mid-2010 Intermittent Shut-Down and Fuzzy Screen

Hi,
My MacBook Pro Mid-2010 has been having some problems recently. Hope someone will be able to help me with this. Below are the symptoms that has been showing.
Symptoms:
1. Intermittent Shutdown
2. Screen going fuzzy (when I give it a slight tap it will be fine but everything just hangs)
3. 3 beep sound
4. Can't start up (The sleep light will just stay on but nothing appears. I have to force shutdown and try starting it again.)
I have recently done a clean install of Yosemite but the problem is still occuring.
I also took it down to Singapore Apple Service Centre to try to get the problem fixed. But the initial tests shows that all the components in the Mac is working fine. I will need to pay for a full test as my Mac is out of warranty hence I did not send it in.
Below is a copy of the recent log after it shut down by itself.
Appreciate if someone can help me with this!
Thank you!
Regards,
Kai Yuan

I just had the same problem! Just installed Mavericks a couple of days ago but everything was running perfectly till just a couple of minutes ago watching netflix and working on Dreamweaver my macbook just shutdown. I had to Turn it back on and in the first try it shutdown immediatelly again, then i tried for second time and as soon as i got back into my account a bunch of programs start sending erros as my clock was set to a different date. My battery seems to be fine, i even check the report in the system preferences, it had 50% of battery and was plugged in so i am guessing that is not the problem.
Here the report:
Charge Information:
Charge Remaining (mAh):          3356

I had to have my motherboard replaced last year as my macbook its a 15 inch Mid 2010 so i took it to Mac Store.. they didnt charge me for anything as it is a problem that Apple acknowledge the problem was in their side. I am just hoping i dont have to deal with this again.

Intermittently shuts down, then slowly gets worse - Satellite P30-133

Hi
Since I purchased this laptop in May 2005 it always had a sudden shut down problem and I am always on Mains!
I did set it as High Power and keep the CPU at 3/4 as well - this way the Fans are working better and the CPU does not overheat.
That was solved.
Then It started to do it again (very rarely) for no apparent reason.
I keep 'all' my computers well updated (drivers included) and lately when I started to do a HDD 'cloning' back up (using
Acronis) it starts the back-up and after a few minutes it shuts down. NOTE: I have been doing this since nearly 2005 wiht no
problems and I have installed the latest update (Acronis), to try and solve the problem.
THe problem is the laptop, as I use that program with other PCs with no problems at all.
Sometimes worked/sometimes not.
Lately (the last few weeks) it started to do it more often and I thought the ext. HDD was gone (I do not believe it!) and I
replaced the ext. HDD with another one I had (new).
It did work fine. Then the next time it did exactly the same (strangely, the other HDD seems intermittently recognised by
Windows (I connected it directly using a IDE/USB lead).
This is not the end.
In the last few days I had this lapto shutting down at its pleasure.
This morning, I switched on and after a few minutes I found it off! - Please note, I do have a new battery too.
Now it starts and as soon as it finished to load windows it shuts down.
I disconnected any external device and still the same - there are no drivers problem.
The other day, when it shut down and I re-booted, windows told me that there was a problem with the Audio driver which I
have installed using the link furnished.
Apart from that, I am completely in the S***
Any help, any idea.
Power supply and battery are new and working fine!
Instead of spending money (I did not want to) on the insurance which is a shambles and never used it (!), I could have purchased a MAC.
You can be very good wiht computers these days, but they are 'mostly' untrustable and all your effort to keep them fine - do
all your backups etc. are of no use and I am a tidy person by nature ! What more can I do? Use my old 386 or 486 - both still
working fine after 20 years?
I do not have a back up and I use it for business too.

Hi
There are F18 and F5 marked screw and you must get them all off.
Some of them are inside the HDD compartment.
I think I have got them all and I am now opening the part near the Screen hinges.
I already opened a Toshiba Pro sometime ago for one of my customers and repaired the DC socket - did it the same day for a business and saved his life! He is still thanking me.
There must be 1 or 2 screw left as I remember the keyboard comes 'swiveling' up towards you at the same time the top part near the screen hinges lifts up.
I have nearly done it!
After you get all the screw out, the silver surrounding comes up a bit, by inserting a tiny blade in the surounding gap.
Last time I did lift the keyboard easily, but not this time.
I cannot lift it !
Done it!
As I remembered the other one.
Just lif tthe silver part near the screen hinges - 'carefully! - and then the keyb has a couple of screws.
Obvious connectors to disconnect, get rid of the screen, etc.
Now I have the whole bottom part wih the mobo and I have taken out a few screws.
I cannot lif the mobo yet!
Once lifted, just a bit of cleaning - when?
Mind I have a antistatic bench and I am earthed!

My FW800 intermittently shuts down using the TB adapter.

When I use the Thunderbolt adapter to connect FW 800 drives to my new MacBook Pro, the drives shut down after a few minutes with a message that they have been improperly disconnected. I bought the computer about a month ago and have already had it computer checked and repaired (by Apple), but that the problem still exists. The drives do work properly when they are connected with USB 2.0 cables, but I need the USB ports for other peripherals and would like the additional speed of the FW 800.
I have read that the Thunderbolt adapter limits the power to 7W. Could this be the problem?

Hello:
As a preface, I do not read logs well at all
I would try running repair disk when booted from your software install DVD.

My Airport Extreme intermittently shuts down completely.

My Airport Extreme (newest model) will shut down completely, all by itself, with the green light completely off. When I unplug and replug the device, it starts again and the green light comes back on after it boots. It's as if a "circuit breaker" cuts off the power. No other equipment shuts off, so it's not the electric outlet.

I just bought a new AE last year and today without any warning it just went off. No light nothing.
Tried to get a light by unplugging and rep lugging, still nothing.
I have had frequent episodes in the past few weeks where the AE dropped the line and I had to run diagnostics to get it going again.
I just put in an order for a new AE, but am wondering if this is normal, only getting one year out of a AE.
This is really bad.. they should replace it even if it is outside 12months.. Just check if you have any applecare or a product you can buy applecare on, and it will cover the AE as well.. lacking anything you have to buy applecare, you can still buy an Apple TV, plus applecare.. that explicitly covers the Airport routers. Do not open the Apple TV.. you can sell it in shrink wrap.. so the purchase of the applecare is all you are paying.
Make apple replace it and keep replacing it.. do not wait.. if it is dropping the line and you need constantly to power cycle.. return it as unfit for use. Routers are supposed to have uptimes measured in months if not years. Daily or hourly reboots is not acceptable.

Computer intermittently shuts down but when i'm using the batter

My MacBook will shut down unexpectedly, even when the batter is charged! This only happens when i'm using the battery to run it. If I plug it in, this never happens.
Any suggestions??

Have you done the battery update?
You might try to reset the SMC and/or PRAM.
If none of this works contact apple you may have a bad battery.

My macbook intermittently shuts down!

Here is the story,
It all started when my macbook would randomly shutdown without any sort of warning. I took it to the apple store 3 times.
1st visit - resent PMU
2nd visit - told me to back up everything and reformatt
3rd visit - finally sent it out to apple
I got it back 5-7 days later and the problem is still happening. It generally happens when the battery is somewhat low, but not yet at the red warning. WHen it shutsdown it will not start back up again until the adapter is plugged in. During startup if the adapter is removed it will shutdown. Im getting very aggrevated with apple and their help on this. What the **** should i do?

Welcome to Apple Discussions!
This program may be of interest to you:

When you call AppleCare, also if you got a replacement battery, refer to this article:
http://docs.info.apple.com/article.html?artnum=304308
Also check if this article applies:
http://docs.info.apple.com/article.html?artnum=303848
If none seems to help, ask to speak to customer relations when you call AppleCare, and tell them what you went through. I would go as far as to ask for a replacement machine if they can't fix it on the next attempt.

G4 mdd dual self shut down

Hi guys.
I need your help to solve this problem:
my dual G4 mdd 1,42 random shut down by itself.
It always happens during a cold start (never when running) and always at the same point, I mean just after grey screen spinning cursor (at the very start of blue sreen) So I reboot and my Mac start up normally, even more fast than normal behaviour, about 5 or 6 seconds less and desktop appears.
The machine is a little overloaded, 3 HD, 3 extra fan inside (2 on PCI slot), Radeon 9800 connected to Hd molex for power the video card.
The PSU is 360 watts.
Any ideas?
Thank you all for reading this post
Rob

Hi-
Welcome to Discussions!
Replace the power cord. If this doesn't alleviate the condition, (from your description) I would consider the PSU to be the most likely suspect.

Mac G4 Freezes/Shuts Down on Its Own

I have a Powermac G4 that when using, it appears to "freeze". The mouse and keyboard become non functional, and the display looks like it is frozen.
BUT The power light appears to be off, giving the impression that the computer has intermittently shut down.
Sometimes it takes a few attempts at pressing the power button to get it to turn back on. Other times, I've pulled the plug and plugged it back in and it would boot up the first time I press the power button.
Every time I boot it back up, the system clock resets itself and I need to put in the time and date again.
I would guess it is the battery or power supply.. are there any suggestions?

Welcome!
Nearly all Macs have a thermal sensing system that tracks CPU core temps and will shut down the computer if it gets too hot. You can get utilities to monitor the temps, like this:
http://download.cnet.com/Temperature-Monitor/3000-2094_4-41089.html
or, since you are in Tiger, this Dashboard widget:
http://www.apple.com/downloads/dashboard/status/istatpro.html
I'm not sure what the critical temp is for an G4. My MDD 1.25ghz single processor has never posted a temp (via Temperature Monitor) greater than 117F/47C but dual-processor machine can run hotter. I thing the 140GF range is getting close to the danger zone.
If temps are running high, there is a physical action and a software action to consider.
The physical action is to make sue that air intakes and exhausts are not blocked. This mean keeping desk clutter away from the front panel and leaving at least six inches between the back panel and any obstruction. Also open the side door and see if there is a convention of dust bunnies clogging the air paths and fans. A good mucking out with a non-static brush can peel several degrees off the temps. I use a kitchen pastry brush with natural bristles and a wooden handle.
The software item is to see if you have a "runaway background process" demanding too much of the processor. The steps:
1) Quite any user applications so the computer is as normal idle.
2) Find and launch Activity Monitor (in Applications > Utilities.
3) If you've not done so before, set AM's "Show" setting (top part of its window) from "My Processes" to "All Processes."
4) Clip on the header item in the table that reads,"%CPU" to sort the processes by their CPU demands.
5) Let AM run for a minute or so. No process should be taking more than about 5% of the CPU if you've quit all other user apps before starting.
If this shows one or two processes hogging the CPU, post their names and we can guide you through taming or evicting them.

Late-2009 Macbook Pro 10.9.2 Random Shut Down

My Macbook has started intermittently shutting down while in use anywhere from 10 min. to 4hrs after startup. I took it to the Genius bar where they advised me to unistall Chrome and remove several Launch Daemons. After removing those, my computer ran well for 3 days after which it began shutting down again. Today it began to shut down (screen off, indicator light off), resist restart (would not power back on for over 15 mins), and then switch back on without going through the normal startup procedures. AHT said that everything was in working order and I have already reset the SMC. Currently I can't keep my computer on for more than a couple minutes at a time so I will post my kernel panic log ASAP.

Calendar Shuts Down After OS4

Okay, this is so weird I hate to even mention it. But after updating itunes and then upgrading to OS4, Calendar simply stops working and shuts down...anytime I try to open up Tuesday. Any Tuesday. Of any month. I press on a Tuesday to look at my appointments on that day and the entire app just shuts off. Anyone experienced this and can help? If it's important, I sync with Outlook through itunes. Thanks!

I have the same problem on upgrading to OS4 on my 3GS. The phone intermittent shuts down and restarts during phone conversations. PITA! I have seen no fixes for this so it's a revert back to older OS, bring on some stability with the iPhone upgrades!
I had the same problem of the phone rebooting during conversastions, after restoring as a new phone as per Apple's CS instructions the problem was still there.
Apple Genuis Bar have now replaced my phone (3gs) and told me not to install the ios4 until I can see from the forums that the bug has been fixed.
Annoying that it happened but credit to Apple for replacing my phone so quickly.

IMac G5 Shuts down while running applications

I installed iLife '06.
Since then my iMac G5 (20") has started shutting down while I'm working.
I'm not sure if the installation is related to the intermittent shut down or if there is another problem.
Someone told me that the fan might be bad. I don't know how to check if the fan is bad. I've heard that some iMac's have noisy fans. I've never heard the fans on my iMac.
I've had my iMac for ten months with no problems.
iMac G5 Mac OS X (10.4.6)

There are two common reasons for an iMac G5 to shut-down:
1) a failing power supply (see the article A. Brody mentioned).
2) Over-heating.
I'll tackle the second one.
All the recent Macs have a protection mechanism built-in. If the system gets beyond a given temperature, the computer will turn itself off (without warning) to prevent permanent damage.
So, if you notice that the computer is running warm before it shuts-off, then that could be the cause.
But, it is also very likely to be the power supply.
And, operating with a faulty power supply could lead to tons of other problems or damage.
So, I would personally get it into a shop for inspection and repair very fast.
But, if it is under warranty, you should not have any trouble at all getting it fixed (either standard warranty or AppleCare).
If it's warranty has expired, see if it is within the covered systems listed in the article A. Brody gave you.
If so, request it to be inspected and repaired for free under terms of that extension.
Regardless of which problem it is, get it fixed. Neither problem is one that should be ignored.
Hope this helps.

What's causing hard shut downs?

My mid-2011 iMac has been intermittently shutting down without warning. The first time this happened it would not restart. I took it to the Apple Store where a Genius ran a diagnostic check and then suggested it was probably power supply related. He unplugged the power cord from the back of the iMac and then the iMac would restart. He said it may never happen again or could repeat. Nothing I needed to do immediately.
I experienced two more hard shut downs during the next 3 months. Each time I was able to restart the iMac. A few days ago it did three hard shut downs in a space of two hours. I again took it to the Apple Store where a diagnostice check was run. It indicated a failing hard drive due to bad sectors (the 500 GB hard drive has about 400 GB free space). Disk Utility showed no problems. I'm assuming the Apple diagnostic check can find problems that Disk Utility misses.
Apple has now had the iMac for three days running "stress tests" to try to duplicate the hard shut down problem without success. Apple recommends replacing the hard drive, but has nothing to say regarding the cause of the hard shut downs.
My undestanding is a bad hard drive does not cause hard shut downs. Does a hard shut down not leave some sort of system log that might point to a cause?

You're clearly thinking about the problem logically. I agree a failing HD should not mimic a "loss of power". Is it possible that your home power outlet is flakey? Voltage drop low enough to cause a trip? I know ground bounces happen at home and the power company will put a meter on one of your outlets. Do you ever see the lights in your home brighten or dim?
When you get the mac back, you should try a different outlet (a UPS would be even better).
