Imac w/ Intel Power Problems. Help!

Power went off in my office, computers are connected to a surge protector. iMac's keep crashing. I remove power to the iMac, wait, both computers reboot fully for about 20 minutes and then crash! help!

Welcome to the Apple Support Communities
If your iMac was running when the power went off, the hard drive and other parts may be damaged. First, try checking your hard disk: open Disk Utility, select Macintosh HD on the sidebar and verify the disk.
If there's a problem, start from the Mac OS X DVD or press Command and R keys while your Mac is starting, open Disk Utility (if you start from a Mac OS X DVD, you will find it in Utilities menu), select Macintosh HD on the sidebar and repair the disk. If it can't be repaired, take the Mac to an Apple Store to get the hard drive replaced.
If your hard disk appears as correct, insert the Mac OS X DVD that came with the computer, press the D key while your Mac is starting to start from Apple Hardware Test and run an extended test. If it shows an error, copy it here

Maybe there's something wrong with your USB cable? Have you tried connecting your iPod with a different cable?

Need advice Imac G5 Intel Duo 2 Core 2ghz will not power up DEAD

Hi all. Hoping for some friendly advice. I have an Imac G" Intel Duo 2 Core about a year old or so. My adult son was using it. Never a single issue and a very mild user. He reformatted it the other night and turned it over to me because he got a new one. I'm thrilled since I'm still using my G4 733 I've been faithfully keeping in operation since April 2001 with almost no issues. The only thing I have done is allow it to auto update everything the night before last. It's set to sleep the screen after an hour and the whole thing about 2 hours. Been working fine and just touch the keyboard and back to life.
Well this afternoon went back to take some more tutorials and it's just dead. As if it had gone to sleep but no amount of button pressing helped. Unplugged everything on USB, firewire. Using apple bluetooth KB and mouse that came with it. Both had new batteries as of other night. Left power cable loose for 10-15 minutes and no help. Held the single power button for long periods, tried holding it while plugging in to wall, tried other wall outlets. Wiggled chord to see if flakey... read articles on resetting some macs but nothing helped so far.
Thanks
LB

Well update I did finally get it to come on after a couple hours of coming back and fiddling. In efforts to fix it I looked up the number on the stand and it looks to be made mid 2007 which means likely no warranty.
I popped out the memory under the little bottom edge cover and dusted off some of the woolies. Didn't help but I blew into the round fan vent on the rear and a good bit of dust even came out the top edge vent. Looks like my son gathered some dust in this thing.
Still thought it would not come on but pressed again and suddenly it's ON and working but the cooling fan seems to be stuck on fast mode. I can't see any way this thing is having heat problems in my office which is a little warm but not hot.
So likely will take into service to clean and dust it out etc and maybe this fan will begin running right. This iMac has never given one ounce of trouble either. I'm posting this using the iMac
Any additional advice appreciated,

HELP ME! My computer is posessed! Very weird power problem!!!!

I am using an iMac - first generation of intel-based iMacs - and I have a very weird powering-on and powering-off problem.
When I plug my iMac into the wall socket, it starts up on it's own. When I shut it down (using BOTH the apple menu OR the power button), it starts itself right back up. When I put it to sleep, it goes to sleep and then wakes up immediately. It does restart normally, though, so it seems that my iMac simply has a problem with being OFF!
Help meh! I'd like to save a trip to the Apple Store if I can help it!

Reset the SMC, as per > http://support.apple.com/kb/HT3964
+1. Shut down the computer.+
+2. Unplug the computer's power cord.+
+3. Press and hold the power button for 5 seconds.+
+4. Release the power button.+
+5. Attach the computers power cable.+
+6. Press the power button to turn on the computer.+

It will do that if the box *☐ Start automatically after a power failure* on the Energy Saver preference panel is checked.

If the SMC and Energy Saver Preference changes do not cure these problems, then you will need to seek service help.

Intel iMac 20' users - any problems with noise on your firewire interfaces?

Someone please tell me that they have a quiet intel iMac 20'/Firewire interface set up, I'm having problems with a lot of digital noise from my Saffire LE & badly am hoping it's 'fixable' or just a faulty unit but more so, praying it's not noise from the iMacs Power supply that will interfere with any firewire interface I get???
I've read many posts about G5's suffering from noisy psu's which was one factor in my choosing an intel iMac & I chose the Saffire on it's great reviews for sound quality, there's no way I can work with the noise I'm getting & I'm pretty much panicking that if it IS the iMac & firewire thats the problem I'll be screwed as i only have 6 pin firewire as a useable option (really don't want to use usb2)
Incidentally, the 'budget' set up I had previously (PC & soundblaster audigy) didnt suffer from any noise like this (at least not that was even audible with the mixer levels at conversational level!) which i guess rules out any blame of this on 'mains hum/interference'?
The noise is there with the saffire's monitor output knob at any setting & with no inputs connected, it;s even worse if i power the saffire with it's external psu instead of off buss power. I'm not using a firewire hub & I've tried switching firewire leads & removing the firewire hard drive i have in the other port in case this was affecting it.
Would really appreciate hearing from anyone with similar troubles or even better anyone thats NOT having this problem with a 20' intel iMac & firewire interface so at least i know there's light (& quiet!) at the end of the tunnel

funnily enough I'm going the other way, I have a rack of external modules/>sampler/fx etc & a crate of looms I've just unplugged as they've not been >turned on in so long!!!
I hear you there!
The noise is there without any inputs at all to the interface, its defiantely >digital though, its like a toned version of the sound of an old telephone >modem.
What I mean, is try disconnecting everything, drives and all. You might even disconnect the interface and crank up the iMacs volume to see if it is there. If it is, you can try the UPS and see if that takes care of it. Then add them in one at a time. All it takes is one cheap power brick in the mix to cause all kinds of trouble (if your using powered monitors, that brick too). Noisy components can actually send noise back into the source power.
I know it can be really frustrating, especially if you have noise coming from more that one source. The key is to strip everything until it is quiet and then add them back in to see where the worst is. Then come up with a plan to try to get rid of the noise.

Imac 27" Intel Core 7 CPU. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware scan and all is fine. Did clean wipe from Mavrick back

Imac 27" Intel Core7 CPU 16 Gig RAM. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware diagnostic and all is fine. Did clean wipe from Mavrick back to Mountain Lion but problem remains. Apple Store can do no more.

I did some more digging, it appears to be a backlight problem only. I can see the screen very dimly if I use a bright flashlight in a very dark room. It also seems to run ok if the brightness is turned down a LOT.
So I'm thinking this is a LED driver board issue or the display itself. I'll open it up and check the connection between the two and see if I can get any more clues. At least I can use it somewhat now by dimming the display significantly...

IMac G5 Power Problem

Hello there,
My iMac G5 ALS 20" 2GHz (bought from new in May 2005) just shut down on me this morning for no apparent reason. I then tried restarting and it now shuts down or doesn't start at all. I had the hard drive replaced a couple of months after buying it, and that appears to be fine now.
There is no warning, it just shuts down with no apparent cause...turns itself off. I have heard there may be an issue with the power unit. What is my best bet for getting it fixed? I don't really want to have to lug it to the Apple Retail store. I have Applecare.
Thanks in advance for anyone's help/advice.

Your iMac may have a problem with the power supply that may be covered by an Apple Repair Extension Program. See http://www.apple.com/support/imac/powersupply/repairextension/ for more info.
My iMac 20 inch purchased in June 2005 started turning off intermittently a few weeks ago and then failed to start (one time) when the power button was pressed. It's been at an Authorised Repairer for a week; however, they can't replicate the problem. I bet if I bring it home it will turn off within the hour!

Grounding (power) problems Imac 21.5"

Does anyone else have this problem with their intel Imac? I am hoping that under my applecare I will get a new computer or a repair. I use my computer for audio at my recording studio and have always used Mac's but this one had me stumped until I found more people that were finding "digital Hash" (digital noise) being recorded with audio signal.
I tore my studio apart only to find it was the computer that was the problem.

What I found was this. When I hooked up my Imac to a mixer via a Steinberg MR816 interface I got what I've seen described as "digital Hash". The sound of the computer processing was being recorded along with the signal I intended to record. I went through a lengthy process of checking each piece of equipment on it's own and in combination. Eventually I plugged a 1/4" cable into my interface and simply touched other equipment (on their metal chasis) to see which piece would generate this noise and create a ground loop. It made the noise with each piece of equipment I touched that had it's own power source and ground. It made the noise even if I touched a screw on my powered monitors. It did not make the noise if I simply plugged in an unpowered instrument like a guitar.
Everything was always plugged into one electrical outlet. I tried 6 different grounded outlets. If I plugged the Imac into a power bar which was not grounded the noise was gone and all the equipment sounded as it should. The Imac was the problem and it was the last place I looked.
But I only knocked out the ground for a moment as I do not wish to run the Imac ungrounded.

Has anyone had a problem with their imac because the power company installed a smart meter which broadcasts the readings to the company?

Has anyone had a problem with their imac after the power company--in my case Pepco in Washington DC--installed "smart meters" which read the meter and transmit the data via wireless? I've had trouble and when I move the imac downstair it disappears. Help!

barryfromwashington wrote:
would putting up a metal shield by the meter help?
It might, as long as the shield is grounded. Metallic (such as copper) window screen is often sufficient.
As mentioned, it would not hurt to file a complaint. The burden of proper shielding should probably belong to Pepco. Among other things, the FCC frowns upon RF leakage and its interfereing with radio communications. Besides, Pepco probably would not want you to affix a shield around their gear - liability issues, etc.
You could experiment by temporarily hanging a shield-screen on the inside of the wall, behind where the meter transmitter device is located, and see if there is any beneficial change.

Here is my problem: "To open "Adobe Photoshop CS5.1" you need to install the legacy Java SE 6 RUNTIME" after upgrading iMac to Yosemite, can anybody help?

This answer may be somewhat late, but just in case other have the same issues, I went to site listed below and it solved the problem. No need to reinstall CS5 product. I hope this works for you.

Connecting an iMAC Power PC G5 to a new iMAC with Intel

i would like to buy a new iMAC with Intel, but i was wondering if i can connect my current iMAC Power PC G5 to the new one? the display on my current iMAC is going bad. the reason i ask is because i would like to continue using some of the software on my current iMAC and just be able to work with them using the new iMAC. i just dont want to buy new software to put in the new iMAC. does somebody have an answer for this? or can i tranfer, for example microsoft office, to the new iMAC?

Nope! As Rick Lang noted, Apple provides "Migration Assistant" with OS X - when you get your new iMac, and go through the setup at power-on, you'll eventually be presented with a "Migration Assistant". To migrate from your G5, it's as simple as connecting the G5 to your iMac via a FireWire cable (You may need a FireWire 800 cable for new iMacs - also called a "9-pin to 9-pin" firewire or IEEE 1394 cable. Shop around - most retail stores, like Best Buy, charge way too much for cables). Then, startup the G5, holding the "T" key. It'll enter "FireWire Target Mode", acting as an external hard drive. Migration assistant while then happily copy all your user data to the iMac - it may take a while. If you've already setup the iMac, you can still use the Migration Assistant - it's in the "Applications>Utilities" folder.
Your applications should now work just fine, with some exceptions. First is that some applications aren't entirely compatible with Snow Leopard (which ships on all new iMacs) - although most currently developed applications have updates to do so. Secondly, you need to check that the apps are "Universal" - that they will work natively on Intel processors. If they are not, they will still work under "Rosetta" - essentially a built-in PowerPC emulator - they will just be slower. Finally, while I haven't had trouble with software licenses, depending on the application you may be required to re-enter the serial numbers/license keys. I can't remember if Office required this, but make sure you have them available.
Also, if you plan to get rid of your old iMac, remember to de-activate iTunes (and other applications that require licenses), and securely erase the hard drive. (Startup via the CD the iMac shipped with, go into Disk Utility, and do a "Secure Erase")
I hope that answers your question! If you decide to upgrade, enjoy your iMac!

My screen has gone blank on startup and occasionally a grey folder with a question mark appears. I have tried rebooting either by pressing the start up with power or pram.. Neither attempts have worked ! My iMac is 2008. Please help :)

Hey Carolinearnold!
I have an article for you that seems to address this issue and can provide some troubleshooting steps for you:

Hi, please, anybody knows how many coolers has an iMac 27 Intel core i5? The widget iStatpro shows 3. I changed my HD (the previous one of 1TB crashed) and after that the HDD cooler is constantly working at 4.600 rpm. Anybody is facing this problem?

Did you replace the HD yourself? If so what HD did you use?
You should be aware that the symptom you describe is likely to be because you've used an incompatible HD. The current Macs have the temperature sensor actually in the HD package, with a modified cable to connect to the logic board.
If the sensor is not in circuit, the fans will run full tilt all the time.
Also, if it was under warranty, I think you'll find you've just voided it.
