IMac wont Power Up

My iMac has an issue, if all users are logged off after a designated amount of time my iMac powers off but the only way I can restart it is to unplug the power cord from the unit wait a few seconds then reinsert the power cord, only then will it power up.

If you have AppleCare, use what you paid extra for...
if it is a failed HD will the apple care replace that or would i be better off just buying a new iMac?
If it's covered, it will not cost you anything to get it repaired. So even if you decide to get a new iMac, you should get this one fixed.
You can try resetting PRAM
http://support.apple.com/kb/HT1379
and if that does not help, resetting SMC
http://support.apple.com/kb/HT1543
which is unplugging the iMac from power and reconnecting it following a precise procedure. When you reconnect it, try connecting it by itself to a wall outlet directly, instead of to a power strip with other devices. Disconnect all of your peripheral devices, except for your standard USB mouse and keyboard.
If that does not get the hard drive to be recognized and working properly, use that AppleCare.

IMac wont power up now!

Hello,
I just back from the apple store with snow leopard excited to install it on my iMac about 2 hours ago to find my iMac frozen and it wouldnt let me hit the shut down button. So i just hit the power button on the mac and now it wont turn on. I tried to reinstall the OS but when i go to install it, it doesnt even show a hard drive to install it on.
I still have apple care for it, so does anyone have any suggestions? And, if it is a failed HD will the apple care replace that or would i be better off just buying a new iMac? My iMac is almost 2 years old, i bought it refurbished from apple.com
Thanks for any help in advance.

My imac wont power up

My iMac froze, so i held the power button on the back to restart it, now it wont restart properly. It makes the chime sound and the fans are working, the apple logo appears and also a loading bar on the bottom of the screen, which i am pretty sure it doesn't normally do that. After around 30 seconds it just powers itself off again before the login screen can appear. How can i fix this?

Carefully read and then methodically follow each of the steps in Gray screen appears during startup

New twist:iMac wont power on

Ok, I've read the other posts regarding this but my symptoms seem a bit different. For about two weeks my iMac has been turning itself off after sitting idle for abou 15 minutes (it's normally on 24/7, although I let it sleep alot). As of this evening, i won't turn on. I press the power button and it goes orange for about 5 seconds (which is norma) then, when it flips to green (this is when it powers up the CRT) it dies.
Help! I need my emal and contact lists!

Robby,
By your description of the problem, it sounds like a classic analog board failure. You must have a tray loading imac judging by how the orange power light turns green then the computer turns off. The problem with the computer turning off after 15 minutes was just the beginning of your problem leading to the end result of not being able to turn on the machine.
I hope this helps in fixing your problem and makes your decision easier to purchase a new mac or purchase a replacement part.

My iMac wont power on either

I have a G3 iMac 400mhz DV that has run with no problem ever. Had a power outage today and now will not power up at all. No lights no static no anything. Pulled battery, put in new battery. Pushed "cuda" button, still nada. Any ideas where to go from here? Is this common?

Try things in Texas Mac Mans tutorial, including what to try if all else fails at the end.
I'll post it here in case you miss it;
-I found this on a Mac site. Sometimes computers lose their mind. Don't ask me why or how it happens but it does. Sometimes you simply have to totally discharge the computer. One thing I have learned about the Blue and white and the Gray G4 Macs is that sometimes pushing the PMU is not enough. If your machine is dead, then try the following.
* Unplug the unit.
* Remove the battery
* Push the PMU switch (count to 5 slow)
* Push the start button on the front of the Mac (count to 5 slow)
* Let the unit sit for 15-30 minutes
* Replace the battery
* Plug it back in, and push the start button
If it doesn't work I usually repeat the steps above, pull the RAM, and let it sit longer. If it doesn't work after this, it is take it to the shop time.
Cheers!

2006 imac wont boot ! g5 cord ok to try?

My late 2006 imac wont power up after a power outage. I did have it plugged into a surge protector tho that is over a decade old by now, didnt think of that earlier. I just get a black screen, no change when i press the power button after it being unplugged.
I Wanted to try the hardware test but the cd drive wont pull the cd in like it normally does when i place it in there.
I have tried an smc reset, no change.
I have an old g5 that no longer works. Im thinking of trying to use the power cord from that to see if its the cord that is the problem. would that be ok to try?

You should be fine trying the G5 power cord.

Why is that whenever there's a power outage or whenever I restart my computer sometimes my iMac wont completely load up? It will just show a blank white screen. It will do that for a few days until it decides to fully load up.

First step would be a PRAM reset.

Post back if that does not work.
The next step would be to try "Repair Disk".

I want to upgrade my ( iMAC 800Mhz Power PC G4 & iBOOK 700Mhz PC G3)

Hello!
I want to upgrade if possible over 1GB ? my now slow computer ( iMAC 800Mhz Power PC G4 ) and a ( iBOOK 700Mhz Power PC G3 ) which I don't think I'm confident enough to change the internal memory but the user memory I think I can attempt!
So I'd like to know what type of ram or "model numbers" I should be looking for if I what to upgrade my empty DIMMO /J22 slot to a 1GB ?
Keeping in mind I still have a 256GB factory standard ram in place (256 SDRAM PC133U-333)
i.e. how many pins "184 0r 200" do I need for for my model?
I seen lots off ram types like "Kingston PC2700, 333MHZ DDR 1GB memory "
PC2700 333MHZ is this the model number I should be looking for to upgrade to 1.256?
and for my ( iBOOK 700Mhz Power PC G3 ) is this also able to be upgraded to beyond the the original ibook specs just like it is suggested for the iMAC? which I also have only the original 256 SDRAM and a empty ram slot! again I not sure what model or type of ram I should be looking for here? or what is the max. it can be upgraded to with the new high density ram everyone is talking about!
I know you guy's must seem to answer these by now simple question for you! am sorry I don't have something more challenging for you but I do need your help with this one please!
since you've already done this and seem to know what your doing! I would like to ask for your help or anyone who know the answers to my questions ?
Thank you in advance!

Unfortunatley, only imac models above 1ghz can take module of 1GB. your model can accomadate 512mb bringing it up to 768Mb which will make a decent improvement.
go to crucial.com and input your imac model to get the right type for your system. it's also best to buy from mac friendly companies as some cheaper modules wont work
best of luck

Imac wont boot, stuck loading, all i see is apple logo and spinning cycle

My 27 inch iMac wont boot, i am runnign snow leopard. I just see the apple sign and the cycle spinning meaning its still loading. I cant use disk utility because leopard install disc wont boot, also i cant run any commands in single user mode, doing /sbin/fsck -fy does nothing, i dont see a # sign or anything, whatever i type it doesnt matter whenever i hit return the cursor just goes to the line below.

Power down (assume you have already tried the SMC reset) and insert the Applications DVD that came with your new iMac. Boot up while holding the "D" key down (may be best with a wired keyboard) to run the Apple Hardware Test according to these instructions:

IMac wont boot up

My IMac wont boot up! I installed the Mac OSX system disk and ran disk utility this is the results:
invalid node structure
The volume Macintosh HD needs to be repaired.
Error: Filesystem verify or repair failed.
What do I do to get this up and running again, I would appreciate any help.
Thanks,
Joe

I called applecare and they were able to get my iMac up and running. Apparently there is an issue with updating software. I just had to do an update today and ended up with the same problem. So I re did what the applecare rep told me and I got it going again myself. I am hoping this will not continue. So anyway, I am going to provide the steps on how my I got iMac going.
1. unplug the computer for approx 17 seconds.
2. unplug everything from the computer except the mouse and keyboard.
3. plug in the computer
4. turn on the iMac and hold down the option key at the SAME TIME
5. when the iMac comes on, it will make a loud beep noise, CONTINUE to hold the power and option key until a small the Mac HD icon displays.
5. When the Mac HD icon shows on the screen, release the power button and option key. Then click on the arrow below the Mac HD icon.
5. The iMac will boot and take you to the desktop. Then click applications
6. choose the utility folder
7 then choose disk utility
8 a screen will appear that states first aid. At the bottom, there will be an option to repair disk. Click on that then choose Mac HD.
9 When this is finished, you are good to go. These steps will repair what ever the software updates are doing to the hard drive.
Hope this helps.

IMac wont connect to internet

OK.. I hope someone has an answer to this...
I HAD a custom built PowerMac G4 Sawtooth that was a faithful machine. Rarely had any problems with it. I have CABLE INTERNET. The G4 connected to the internet FINE via Ethernet. I recently bought an iMac Intel Core Duo from a friend and proceeded to use the migration assistant to move my files over.
The iMac now serving as the main machine WILL NOT connect to the internet via the SAME ethernet cable and modem setup that the G4 had ZERO problems with. Fortunately my neighbor has wifi and im able to use his.
I just dont get it though, WHY WHY WHY will the iMac not connect? It says its connected to the modem but the internet just fails. Ive tried power cycling so i know that wont work. This is DCHP, it should just work.... ?
To make matters worse, during the transfer from the G4 i forgot to eject the system properly and shut it down while in TDM. So shes dead... Wont power on at all.
So i have no other system with which to check the internet connection on. This is the first time ive ever had something like this happen.. Im actually frustrated with my MAC. :-/
HELP!

Hi SanHachi, and a warm welcome to the forums!
Did you power down the Modem yet?
They normally only remember the last Hardware connected, power it down completely for 5 minutes, power up, power up Mac.
Then... Try putting these numbers in Network>TCP/IP>DNS Servers, for the Airport Interface...
208.67.222.222
208.67.220.220
Then Apply
DNS Servers are a bit like Phone books where you look up a name and it gives you the phone number, in our case, you put in apple.com and it comes back with 17.149.160.49 behind the scenes.
These Servers have been patched to guard against DNS poisoning, and are faster/more reliable than most ISP's DNS Servers.

Imac wont boot - i get a white screen with apple logo, and it loads to about 10%, then screen goes black

imac wont boot - i get a white screen with apple logo, and it loads to about 10%, then screen goes black

Hey there mtriest,
It sounds like you are unable to boot the iMac successfully as it keeps shutting down when you try to boot. I suggest the troubleshooting from the following article named:
Mac OS X: Gray screen appears during startup
http://support.apple.com/kb/ts2570
Disconnect, test peripheral devices and network cables
Note: "Peripheral devices" refers to external devices other than what came with your Mac, such as hard drives, printers, or hubs that you connect via a USB or FireWire cable.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Disconnect all peripheral devices such as external hard drives or printers (leave only the display, a keyboard, and mouse connected).
Disconnect any Ethernet cables.
Start up your Mac.
If you can start up this way, one or more of your peripheral devices (or installed software related to the device) is probably causing the gray screen issue. Connect one device, then restart your Mac to test for the issue. Repeat the process until you locate the device at issue. Make sure the device is powered if it needs to be to operate correctly. Check with the manufacturer of the device for support or possible software driver or firmware updates that may be available for the device. Try a different cable with the device if possible (such as a different USB or FireWire cable).
Note: If you have multiple peripheral devices and the issue only occurs when they are all connected, but not when each device is the only peripheral connected, see the Additional Information section below.
If you are using a desktop Mac with a third-party keyboard and/or mouse device, and the issue still occurs, try starting up with an Apple keyboard and mouse connected instead. Try starting with no keyboard and mouse connected, then connect them after start up. Also, try a different USB port on your Mac.
If the gray screen issue persists with no devices connected, go to the next section (with the peripherals still disconnected).
Perform a Safe BootSimply performing a Safe Boot may resolve this issue.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Start your Mac, then immediately hold the Shift key. This performs a Safe Boot. Advanced tip: If you want to see the status of a Safe Boot as it progresses, you can hold Shift-Command-V during start up (instead of just Shift).
Note: A Safe Boot takes longer than a typical start up because it includes a disk check and other operations.
If your Mac starts up as expected, immediately try restarting.
If the Safe Boot does not work, or the restart after a successful Safe Boot does not work, go to the next section.
There is additional information in the article with further troubleshooting if needed.
Thank you for using Apple Support Communities.
Cheers,
Sterling

IMac wont shut-down

Hi folks,
i`ve got an Intel iMac 24 inch 2.16 GHz Intel Core 2 Duo with Mac OS X 10.4.11 installed. Very often the iMac wont shut-down. When i choose the shut-down command from the Apple menu the Finder quits, the Icons on the desktop, the Dock and the Menu bar disappear. Then the screen turns blue and i see the grey spinning wheel but it wont go further. I always have to disconnect the power cord to shut-down my iMac. Here is what the system.log says:
Mar 18 18:28:49 macvier shutdown: halt by anita:

Perhaps this is an app booting on launch that's not helping matters. Here are some ways of preventing items from opening automatically ...
If the login window appears when you start up your computer, hold down the Shift key and click the Login button. Continue to hold down the Shift key until you see the Dock.
If you don’t see the login window when you start up your computer, hold down the Shift key when you see the progress bar in the startup window. Continue holding down the key until your desktop appears and the startup completely finishes.
Choose Apple menu > System Preferences, and then click Accounts. Select an administrator’s account, and the click Login Items. If any unwanted items appear in the list of items that open automatically, select the item and click the Delete - button.
You could try resetting the SMC. http://support.apple.com/kb/HT1543

Syncing iphone and now phone is stuck and wont power off or do anything

syncing iphone and now phone is stuck and wont power off or do anything

Reboot the phone: hold down the power button and the home button at the same time until you see the Apple logo. Ignore the "slide to shut down". When the screen has been completely black for a few minutes, press the power button again.

Macbook pro 15" mid 2010 i spilled water on keyboard now it wont power on if the battery is connected and the keys on keyboard doesnt work it works fine with no battery and external keyboard if i order a battery and new keyboard will every else work again

macbook pro 15" mid 2010 i spilled water on keyboard now it wont power on if the battery is connected and the keys on keyboard doesnt work it works fine with no battery and external keyboard if i order a battery and new keyboard will every else work again lik it did before

If you have records that show that you've taken your MacBook Pro in for a year to fix the machine, I would escalate the problem to Apple Customer Relations - unfortunately I don't have a number for Spain.
It would only seem logical to me that if you've been trying to have the machine repaired during the time that the 'recall' was in effect that you should be eligible for a new logic board. But only customer relations will be able to make that call.
Good luck - take the issue as high up the food chain as you can and see what happens.
