Imac G5 Fans running constantly and computer goes into sleep mode

I have the first gen Imac G5. Since I've purchased it I've had this problem, they told me it was the lower fan and I had it replaced twice before my warranty was out. It seems to work for a month or two, then goes back to the same thing. I have all apple ram, I've reset the pram and the smu. I recently ran the apple hardware test and the code it come up with was (2STH/1/2:CPU T-Diode). I'm out of all options, and since everyone else is having this problem or similar problems I was wondering if someone might have a solution since apple won't fix this problem or recall it. It even does it when I have just Itunes open. All I know is that everyone is having a problem with these early model Imacs and Apple won't do anything to fix it. Please help me solve this problem.
Imac G5 without Ambient Light Sensor Mac OS X (10.4.4)

All I know is that everyone is having a problem with these early model Imacs and Apple won't do anything to fix it.
I can understand your frustration, but I'm not sure that that is fair, Jeffrey! Apple have a two year extended repair program in operation for the first generation imacs to deal with the common issues related to capacitor problems and the like - see http://www.apple.com/support/imac/repairextensionprogram/

Apple tv loses home sharing when my computer goes into sleep mode

Just recently, my Apple TV says that home sharing is off when my computer goes into sleep mode. It never used to do that - any suggestions?

I have the same problem here. Always back-ed up with Time Machine (OSX 10.9 Mavericks) to Western Digital drives. MyBooks, MyPassport 1TB (USB 3.0), all works fine. Time Machine is actually doing back-ups overnight. Since I got this new 2TB MyPassport Ultra USB 3.0 it's working perfect during days, but every morning when I wake up the MacBook from sleep, I get this annoying error:
Time Machine couldn’t complete the backup to “MyPassportUltra”.
Unable to complete backup. An error occurred while creating the backup folder.
Latest successful backup: Today, 02:27 am
I'm also not able to write anything to that drive, or unmount it. It stil shows up in Finder, and I'm able to read all the data perfectly fine. When I do a Disk Utility Verify Disk directly after, I get this:
Checking volume
disk3s2: Scan for Volume Headers
Invalid Volume Header @ 0: I/O error
Invalid Volume Header @ 2000021315072: I/O error
disk3s2 is not a CoreStorage volume
Error: This disk needs to be repaired. Click Repair Disk.
I don't click Repair Disk, as this will probably screw up my partition. Instead, I have to unplug the USB cable (which is bad for the drive, there's no time to park the drive's heads) and plug it in again. After clicking Backup Now, Time Machine immediately starts backing up, and the drive works fine the rest of the day.
I contacted WD Support, and they are sending me a booster USB cable. As System Information reports, the drive receives enough power though:
Current Available (mA): 900
Current Required (mA): 224
Unfortunately there's no firmware update for this drive, which will probably fix this. See this topic: https://discussions.apple.com/thread/4196704.

Computer Goes Into Sleep Mode By Itself

Experiencing a weird phenomenon this morning... my PowerBook is sending itself into sleep mode. The battery is charged and it's not overheated. It does it when plugged in and when unplugged.
When I hit the 'power' button to wake it up, it always comes back on, but then shuts off 10-30 seconds later. It's now been on without sleeping for ten minutes or so, but would still like to know what's causing this very un-Mac-like behavior and how to fix it.
Thanks,
Matthew
PowerBook G4 15" Mac OS X (10.3.9) 100G Hard Drive

Back to the beginning, then. Are you certain the Powerbook is actually sleeping? Is the sleep light pulsing? If not, the problem is that your backlight is going off, not that the PB is going to sleep. That would most likely indicate a bad inverter board. When the backlight goes off, shine a bright light on the screen, or shine a bright light through the Apple logo from the back side of the display. Can you see the screen image that way? If so, replacing your inverter will probably solve the problem — and if the inverter is failing, nothing else will.
EDIT: BTW, I meant to mention this earlier but forgot. In your original post you implied that you habitually hit the Power button to wake the computer from sleep. That's probably not a great idea, since there's a small risk that you'll accidentally shut it down that way if you aren't really paying attention. I always wake mine using a Shift key, which carries no risk at all of causing anything odd to happen — not even of typing a stray character into an open document, or moving the cursor from where I left it.

The plugin container crashes if the computer goes into sleep mode or screensaver mode

it seems everytime I put my computer into sleep mode or if it goes into screensaver mode the plugin container crashes

Update it appears that if I leave like a video or game open while I leave or turn it into safe mode it crashes it

Early 2008 iMac (8,1) randomly goes into sleep mode

Hey,
My early 2008 iMac (8,1) on 10.8.2 goes into sleep mode by itself. I've played around in Energy Saver, tried resetting SMC, NVRAM, replaced HDD, reformatted HDD, installed smcFanControl, reinstalled Snow Leopard, Lion, Mountain Lion. None of that worked. Took it to the Genius bar, performed some diagnostics tests and they said everything worked properly. Does anybody have the same problem? I can still use the computer for general computer use (light web surfing and e-mailing), but it seems to go into sleep mode when I have a lot of applications open and especially when watching videos. I've tried researching this problem, but I've haven't found a definitive answer. Right now, the Genius that I've been talking to thinks it may be the RAM. I'm waiting on new shipments of test RAM to arrive at the Apple Store for him to properly diagnose.
Thanks,
Jason

If you want to read the whole time line, I've included it here. I apologize for it being so long.
At first I was running Lion (10.7.5) and the computer would enter sleep mode whenever I was doing anything with video. For example, watching YouTube videos and chatting on FaceTime. And funny enough, I distinctly remember watching a bunch of movies with VLC and the computer did not go to sleep (Although, this is not true anymore). I could wake the computer up and use it, however within a few minutes the computer would re-enter sleep mode. The computer seemed fine and I could access all of my files. Tried resetting SMC and it did not resolve the issue.
I made a Genius appointment to see if they were familiar with the issue. The iMac passed the in-store diagnostics test; it said all the components were functioning properly. He told me to bring it home to do a fresh re-install of my OS and then run my computer to see if the problem persisted. I took it home and reformatted my HDD with a 35-pass erase, re-installed Snow Leopard (10.6.8) and declined to transfer any backups from Time Machine. I was using a fresh system and sure enough, the problem persited. Tried doing the same thing again but with Lion (10.7.5) and still no luck. So I made another appointment and it passed the in-store diagnostics test again. I let them keep the computer for a 24-hour diagnostics test. They told me they would diagnose my computer with the OS on my HDD as well as a copy of OS that the Apple store deemed 'good' on an external HDD. The Genius called me and told me that my HDD failed their 24-hour diagnostics test and recommended I replace it. I initially had a 750 GB HDD, and the Apple Store could only offer me a 500 GB HDD ($200). I opted to take my computer to Carbon Computing, an authorized dealer in Toronto, to have a 1 TB Seagate HDD ($170) installed with no OS on it. I brought it home, performed another 35-pass erase and installed Snow Leopard. Problem still persisted. Repeated with Lion, still unsuccessful. Looking back, I was so excited that I just had to replace the HDD to fix the problem, I forgot to ask the guy if he could recreate the issue.
I began to suspect that it was a heating issue. So I installed Temperature Monitor and smcFanControl, and cleaned the fans as much as I could without taking the computer apart. Without smcFC on I tried to recreate the problem and I noticed that the Power Supply Position 1 reached 95 degrees Celsius, and Graphics Processor Temperature Diode reached 97 degrees Celsius before entering sleep mode. I don't know much about temperature sensors and what they monitor specifically, and so I couldn't draw any conclusions from that data. I turned on smcFC and cranked the optical drive speed to 2000 RPM, HDD to 3000, and CPU to 3000. The computer still went to sleep but the temperatures were below 90 degrees Celsius before entering sleep mode. I've tried researching here and on the internet about normal operating temperature ranges of iMacs and generally found that most do reached that temperature but they do not go to sleep mode.
Then I thought it may be a problem with Lion so I upgraded to Mountain Lion. The issue still persisted. Tried resetting SMC and NVRAM, did not resolve issue.
I called the same Apple Store explaining to them that their recommendation of replacing the HDD did not resolve the issue. They told me to bring it in and have them check it out again. I went through the same process I did before; the iMac passed all of their diagnostic tests. The Genius told me this time he will test out the RAM. He called me and told me that he could replicate the problem and so he proceeded to put in a stick of 'good' Apple RAM, but the computer would not work. He said the 'good' Apple RAM was damaged, either before or in the process of putting it in. He plugged in my old stick of RAM and the computer worked. He tried to recreate the problem and claimed that the computer ran for over 24 hours with an existing movie on my HDD playing and it did not go to sleep mode. However, once I brought it home I played the same movie right away and it turned off 17 minutes into the movie. Tried resetting SMC and NVRAM again, ran the movie again, still went to sleep.
And that's the story for now...

Now to find out WHY it does it at home only. How hot is it at home? Have you checked the AC current/voltage at home?
Well they were able to replicate the issue at the Apple Store the second time I left my computer there. Anyway, we don't have any heating on at my house at the moment. It's usually from around 20-23 degrees Celsius (72-75 F). Temperature Monitor says ambient temperature is 30 degree C though...
I'm not really sure how to check the AC current/voltage at home, but my computer worked before I moved it. So I'm not sure if that is the issue.
I normally only have speakers set up to my computer and a wired keyboard. The speakers are powered separately. I would assume that at the Apple Store only the power cord and wired keyboard are connected.
What is the Power Supply Position? And what does it do?
Thanks for your help!

RBDAPP01 going into SLEEP Mode and Idocs still in 64 status

Hey all,
I have a Inbound Idoc interface which is being processed using RBDAPP01 Program. The Issue I am facing is that the job running the rbdapp01 program goes into sleep mode even though there are idocs present in 64 status. I tried to debug the work process using SM66 but it does not open any debugging window although it says debugging started. If I cancel the Job and run it again it processes those Idocs Any input on how one can resolve this issue?
Thanks.

Hi Aparna,
Here is extract from SAP material on running RBDAPP01 transaction and possible reasons for delay in processing. HOpe this can help you.
To automate the treatment of IDocs, you must run the ABAP program RBDAPP01 (transaction BD20) in job. This program has a very good option for parallel processing which can reduce a lot the time required for treatment. However use it carefully and make sure you set a packetsize high enough to avoid that your SAP system be overwhelm by demands for available dialog tasks (don't forget one dialog task is monopolized per IDocs packed to treat).
Best Regards,
Krishna

Cant connect to internet after computer goes to sleep mode.

Everytime my computer goes into sleep mode it wont let me connect back to safari. It shows im connected but wont connect. Can anyone help me?

Hi there. I have the same sort of problem with my MacBook. To get the internet working again I have to restart the system. Sometimes the same sort of thing (shows I'm connected but doesn't really connect) happens when I'm in the middle of using the internet. I've posted a topic ("Problem with AirPort?") about this also and I've gotten a few responses already. Maybe one of them can help you out (no luck for me so far though).

MacBook goes into Sleep Mode w/o me telling it to

An iPod-like image pops onto my screen with "Zzzz" coming out of it. Then my computer goes into sleep mode.
This has happened a couple times. Once, I did not have it plugged in. The other time (just now), it was plugged in. Neither time was my battery even close to low power. Neither time did I come close to touching something that would put the Mac to sleep. I have checked my power settings, and they are all correct. For instance, I have the power/screen not shutting off when it is plugged in.
Any ideas???

Got the exact same problem here - I have it plugged into power and my on-power setting says "never sleep" and yet keeps trying to go to sleep (actually I think it is shutdown) when I leave it alone for a hour or two. Most of the time I have stuff running that it can't close automatically so I come back to a window full off dialogs asking for quit confirmation.
Very irritating - is my Mac just trying to be green? Is it somehow thinking its in battery mode? Is there some more obscure setting that will prevent this?
Or is it just a bug...

Macbook Pro fan running constantly and CPU running slow

So, I have a Macbook Pro 2010 2.3 i7 that has started running really slow and the fan is running constantly.
In activity monitor it shows a kernel_task running constantly at around or above 200%.
I have tried all the regular tasks. PRam reset, SMC reset and nothing seems to fix it.
I have also tried a system reinstall to no avail.
Maybe I'm on the wrong track, but from what I have read, the kernel_task might be trying to slow my CPU down because it thinks it is being overworked?
Maybe the fans are also being activated because it thinks the computer is too hot?
Anyway, if anyone has any idea as to what I can do to figure out what is going on, let me know. Thanks

Updated to OS 10.7.3; fan runs constantly and battery life dropped to under 2 hours when 100% charged. How do I get back to 10.7.2, I don't have a backup prior to this upgrade. This is a newer Macbook Pro 13", no modifications.

Help! This new version of Lion is making me miserable. The fan runs constantly, the computer is hot and battery life has dropped to under 2 hours on a fully charged battery. I updated yesterday, nothing but misery today. Even running the mail program alone make the fan run like I have everything open. Using Pages, iPhoto, and iTunes simultaneously makes the computer blistering hot.Yesterday, I could use all three without any trouble. Any suggestions to either jettison 10.7.3 or how to fix without any expense? I haven't modified this computer at all, it is as it came from the box in August 2011: 2.3 GHz Intel Core i5, 4GB 1333 Mhz DDR3.

I updated to Lion 10.7.3 and started noticing my fans running on high all the time and my battery would drain 2-3x faster. I was going to take my computer into an Apple store until I found this thread. I did the SMC reset by shutting down my computer, plugging it in, and then pushing down shift+control+option while also pushing down the power button. Nothing happens on the screen and the computer did not turn on. I then released all the buttons at once after holding them down for 10 seconds.
After that, I simply turned my computer back on and everything seems to be working fine. The fans are not blasting anymore. I have a newer MacBook Pro where I can't access my batteries. The SMC reset may differ for other types of laptops.

My iMac goes into sleep mode, won't come out until I unplug and replug the computer then hit the power button. Just hitting the power button alone won't restart the iMac.

My Imac goes into sleep mode but won't come out. The keyboard/mouse won't rouse it and the power button won't do it either. I have to unplug the computer, re-plug it in and then hit the power button. Help?

I looked around the internet and found an old post that seems to have solved the problem. I had a relatively new USB port (powered) that I unplugged and, ta da, the problem disappeared. I'm not sure why this happens (I'm not a tech person) but it seems like this should have been worked out in testing somewhere.

Updated to windows 10 and now my computer stays black when it goes into sleep mode

I just updated my computer to windows 10. Whenever it goes into sleep mode and i try to move the mouse it just stays black and i have to turn my computer off and then on again. after that it finally works but its just annoying. I already tried updating my card driver, but it said it was already up to date.

My iMac i7 quad was having the same symptoms with the blue screen and long startup times a couple of months ago. Apple Care told me to bring it in to the local Apple Store, and after some diagnostics, the hard drive required replacing. It took one day to replace the hard drive and my iMac is running great. I only had the iMac for about 12 months when the drive needed to be replaced. Not sure if that is your Mac's problem, but it was for mine.

I'm using a late 2006 2.33GHz imac.I clean installed 10.6 from disc then updated to 10.7 from download.Now every time my computer goes into sleep it won't wake up.Anyone know how to cure this problem please??

I'm using a late 2006 2.33GHz imac.
I clean installed 10.6 from disc then updated to 10.7 from download.
Now every time my computer goes into sleep it won't wake up.
The only way it will restart is to pull the mains lead out of the imac, put it back and try until it will start.
This only happened after reinstalling. Only Apple OS was on the imac and so it must be an issue with the software I believe.....
Anyone know how to cure this problem please?
Thanks
paul

This isn't a fix, more a workaround I used when I had wake from sleep problems that lasted from some point in 10.6.x, through 10.7 and into 10.8 (got fixed for me in 10.8.2). It seems to be connected with Bluetooth failing to wake up properly:
System Preferences>Energy Saver and set 'computer sleep' to 'never'.

24" imac goes into sleep mode and lights on circuit flicker

Hi -
I have a 24" imac and have found that when the display goes into sleep mode the lights on the circuit flicker.
I have searched the web and other users have complained of the same issue with no resolution.
Here is a similiar post - https://discussions.apple.com/thread/2606099?start=0&tstart=0.      The resolution is probably you need to get the iMac serviced, what i'm wondering is what is the problem in the imac that is causing the issue.    Is this a defect?
Before anyone questions the circuitry in my house here is what I have verified.
An electrician has come and verified the electric panel is good and all circuit breakers are good.   All circuits in my house are copper, no aluminum.
I can plug the iMac into any circuit and the problem starts right when the Imac's display goes to sleep.     I have owned the iMac for approximately 5 months now (bought it used) and the problem started about a month ago.
Assuming this has to be serviced I dread to wonder the price .
Thanks for anyones help.

The sleep timeout has nothing to do with disk activity. It's based on user input, although some background processes can pre-empt it. If you don't want the machine to sleep automatically, disable automatic sleep in the Energy Saver preference pane.

Week old IMac G5, Version 10.5.2, goes into "sleep" mode randomly....

My sister has a brand new IMac G5, OS X version 10.5.2, the screen randomly will go black, it still stays on, it's like it goes into sleep mode, but force quit wont work, nothing works, restart is required in order to get out of it.
On another note, when she restarts the computer, and sometimes when she's just starting it up not on a restart, the computer will have colored lines running down the whole screen, when it gets to the blue loading screen, it freezes there, where once again it requires a restart. Problem is, the computer is less than TWO WEEKS OLD. I've had my mac for years and cant figure out the problem, anyone that knows of, or has had similar problems and had them fixed that could help out would be nice. Thanks!

In fact, what your sister has is an intel iMac, not a G5, those were discontinued a couple of years ago. She has telephone support for 90 days and should call Apple immediately for a solution to her problem.
