IMac not turning on after power outage

The new iMac arrived and I register at the beginning screen, etc. I'm at the end of the registering when I accidentally pulled the cord out of the iMac. Now when I try to turn it on, nothing happens. At all. I've tried taking out all devices, etc. Nothing will work.

first, please explain what You did here...
is the line cord still in tact?
the power connection, on the back of the iMac, is it loose?
Thanks,

Imac will not start up after power outage

My iMac G5 will not turn on after the power went out. I can hear a clicking noise which seems to be coming from the fan/power supply area when it is plugged in. Nothing happens when the power button is pressed. Tried resetting PMU and still nothing. What do you think the problem could be? Bad power supply?
Thanks.
iMac G5 17" Mac OS X (10.4.9)

I just went through the steps of troubleshooting with an iMac that won't turn on using the led indicators with the back taken off, the first led light lights but it seems to blink very quickly (in unison with the clicking noise), does not stay solid. After pressing the SMU and then the internal power button, nothing happens again, and the 2nd led light does not light even momentarily. So it tells me that I need a new logic board...what kind of costs are we talking about here, anybody have a ballpark idea? Thanks for the help.

IMac G5 does not turn on after power cord knocked off

I have an iMac G5 that I recently passed on to my daughter. For the past few years it has been working fine except for one occasion that I replaced the power supply. At that time it was still covered by warranty and Apple sent me a replacement unit that I installed myself. Lately, the power cord was knocked off while the computer was on and now it will not turn on completely. It starts for about 15 seconds up to the gray Apple logo then the screen goes blank. I monitored the LEDs and all 3 do turn on then the computer shuts down. At first I thought it's the power supply that was affected with the power cord accident, and bought a replacement unit. I have just installed it but still the same problem exist. I am now asking for help from the expert souls out there to save this computer. Thanks.

No more ideas except to try starting from the install disc and see if that works. Resetting the PRAM might jolt it back to life, it's worth a try, but I am not hopeful.
If you do take it in, please let us know whether it was the logic board...

IMac won't boot after power outage

I got a power outage a couple of hours ago. And now my iMac won't boot. When I power it up, it gets pass the white screen with the apple logo. The screen than turns blue with a spinning cursor. The cursor spins for about 10-15 minutes and stops but the normal login screen never appear and it won't boot into the desktop either. I just got a blue screen.
I have boot into the install Disc1 and did the disk repair and premission repair but it didn't help.
Any idea?
Sidney

Oh man, what a disaster!
I tried to do an Archive and Install but the installation hanged at the end of disc 2 after running an iWeb script (according to the install log) with about one minute left. I have waited for two hours but it just hanged there with all the drives spin down.
To make the problem worse. There was no way to quit the install at that point because all the menu items were disabled. The only way out was to power off. But when I powered it back on, it booted right into install directly asking for the disc 2. If I put the disc in it will install again and hang at the same spot.
Disc 2 contains iLife. I know Apple wanted to make things simple but why can't they give me an option to skip it? After all, iLife was already installed.
I finally got it working by booting from disc 1 and did a clean install. It took me all night to re-download all the updates and reinstall many applications. Fortunately, I have my address book, calendar, and most of my works backed up to .Mac so it wasn't a total lost.
On the bright side. Now my iMac is working better than before. I used to have problem getting auto sleep to work but now it works perfectly. Safari also had problem accessing charts (but Camino was fine) in a few web sites like schwab.com. Now everything works.
Lenn and David. Thanks for all your helps.
Now I am looking for a better backup solution so that the recovery won't be this painful if disaster strikes again. Any suggestions?

HP Photosmart 6510 B211a Not Functioning Correctly After Power Outage

Hi Guys,
I'm new to this forum but I'm hoping someone can help me.
I have an all-in-one HP Photosmart 6510 B211a that has been working like a dream since I got it last Winter. We had an unforeseen power outage yesterday however and once the power came back, the printer insists that there is no ink in the system. I fear the worst and think its brain may be somewhat scrambled.
I replaced two of the ink cartridges just last week with genuine HP ones and everything was fine. My ink levels are nearly low on the other two but I have not replaced these yet as there is no need.
Once the power came back, the printer informed me that the magenta ink was 'missing or damaged'. I removed the cartridge, cleaned it with distilled water and dried it. Once replaced, the printer changed its mind and told me all ink cartridges are now 'missing or damaged'. When I opended the printer again, the ink carriage did not automatically move as normal to allow me to change or remove the cartridges.
Furthermore the touchscreen on the printer will not allow me to exit this error message or perform any other function such as head cleaning. I have tried a soft reset and a hard reset but this has proved fruitless.
Is it knackered? Should I toss it and head to the shops again?
Thanks for reading this,
Brendo
This question was solved.

Hi Rich,
I replaced the magenta cartridge yesterday and my printer is working successfully again! Woohoo!
My dad's an electrician so between us we've come to the conclusion that when the power came back on after the outage there was either an electrical spike or insufficient voltage than normal and this damaged the nearest ink chip to the power supply - the magenta cartridge.
All is well again anyhow.
Thanks for your help - I appreciate it

Desktop will not come on after power outage

We had a power outage for about 5 seconds. Everything came back on. When I hit power button on PC, it came on and booted back up. About 3 minutes later, it cut off. I restarted it again and it did same thing again. When I tried to turn it on again, nothing happened. It has a green light above power cord lit up but when I hit power button, light goes out. PC was on surge protector when power went off.

Here is the standard HP diagnostic for the power supply. Likely it has been damaged by the spike. The slimline's use a specialty PSU, called a TFX is most cases. It would help if you'd mention the exact model #. Examples, more.

IMac not turning on after PCIe attempt.

Hello, I'm looking for some helpful tips, I tried to put a USB 3 PCIe card into my iMac and when I started it up I got no display.
I figured perhaps my iMac didn't support the card and took it out, still no display. Then I thought maybe I blew my display card because I didn't see
the fan moving (fan on the display card) so I switched that out with one that I was 100% worked and still no display.
When I press the power button I hear it booting up and then I hear the fan and the white light in front stays on but I get no chime and no display, I tried using VGA and DVI, I checked that everything is connected, I don't know what else to do and I need to work on a project for my boss asap, any suggestions? Please and much thanks in advance to whoever answers.

I'm thinking the drivers must be intel only and I didn't know until after installation. I wanted to use usb 3 for faster file transfers to my usb 3 portable drive. I don't think the problem has to do with wifi and Like I said before I took the card out and even changed the display card but i'm still not getting any response. And I don't think it's power issue because the fan starts up on the Display card.

IMac not booting up after power failure

work around for at home/personal users which should work, the OS try's to retrieve user authentication Info from the previous logged on user so disconnecting the network cable or disabling or turning off the WiFi/ wireless should do the trick, just make sure the power is fully drained or have the power cable or battery disconnected for 25-30seconds to ensure the power is drained from the system. For all those Domain Admins/Users enable do not write on the users directory so the OS doesn't recognize a user account to try and retrieve info, if you perform this the OS will just create a temp user profile folder and delete it when theirs a power failure and not try to look for it after the power failure when booting up not causing to give you the gray boot up splash screen and go right into OS X, hope this helps and good luck!

IPOD will not turn on, after power ran out and charging for two days.

Slept off while using my IPOD, noticed the next morning that the battery was flat, i charged the IPOD, for one day, try to turn it on nothing happened, charged it for the second day, same thing, it refuses to turn on. Please i will like tips and help on how to go about resolving this problem. Note a friend had same problem and had to charge hers for one days before the IPOD turned on.

If not this:
iOS: Wi-Fi or Bluetooth settings grayed out or dim
One user reported that placing the iPod in the freezer fixed the problem. A trick that works frequently with iPhones:
Settings > AirPlane Mode ON, Do Not Disturb ON
Power down and wait 5-10 minutes
Power up
Settings > AirPlane Mode OFF, Do Not Disturb OFF
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.

17" Powerbook G4 1.67 GHZ - Will not turn on after power surge !!!

This is showing no signs of life after a power surge. Here is what I have done so far:
AC Adapter - Test OK
DC IN Board - Test OK
PRAM Battery - Test OK
There is power getting to the logic board, but absolutely NO response when you press the power button. I have tried the oh so famous PMU reset and zero response. The AC adapter glows amber, and no chimes or beeps. Has anyone had the same experience or could steer me in the right direction. I am very fearful it is the logic board, any sugestions?

You might want to take it to a repair shop. Something similar happened to me, but the repair shop took care of it in a few days. (The only things I lost were all the apple loops in GarageBand, but that's fixed too.)

IMac 2ghz won't turn on after power loss

I really hope someone can help me. My 07 or 08 2 ghz iMac will not turn on after losing power which includes being unplugged or the power being turned off. This happens whether or not it is shut down properly. Once it will not turn on it must be unplugged and sit for about 12 hours or be plugged into a different outlet. Outlets are all fine. Have reset pram and all that stuff. It is surge protected. Any suggestions? Thanks

I have been having exactly the same problem as Mhuntet11.
My 2010 i3 iMac will not turn on after losing power, which includes being unplugged or the power being turned off.
It has happened to me 4 times now. In each case - nothing will get it started. But on each occasion - about 2 days after the power cut - the iMac will start up again, good as new.
I have also experienced the other thing that Mhuntet11 said:
"when it won't turn on I plug it into a different outlet and if it does turn on I can unplug it and put it back in the original outlet and it works fine"
Yep - once, after 2 days of trying every power point in the house, I finally started up in the kitchen. Not very practical, so I bit the bullet and powered it down again and moved it back to the office. It stared fine.
Does this sound like a fault that should be serviced? Or is there some re-set technique I do not know about.
I have followed the SMC reset procedure and it does nothing

My AppleTV stopped working after power outage. Light is on and I rebooted and reset w remote but it keeps giving me a pic of the Hdmi cord like it is not recognizing the hdmi as being plugged in. I've unplugged it several times.

It is in recovery mode. The picture is telling you to connect to iTunes via micro usb cable in order to restore.

My iPod 5th gen is not turning on after iOS 8 update!

My iPod 5th gen is not turning on after iOS 8 update! Before this all happened, I noticed that my apps crashed unexpectedly, it was laggy, and it decides to reset on its own at times. I CAN'T charge or plug it into my computer. Also, my home button is sunk in but my sleep/wake button at the top is most definitely not. I know my iPod was not running out of battery and I did not even power it off. I am very disappointed but I really need it to turn on =/

Try:
- iOS: Not responding or does not turn on
Ignore the reset and when it says place the iPod in recovery mode
Place the iPod in recovery mode using one of these programs:
For PC
RecBoot: Easy Way to Put iPhone into Recovery Mode
or

RecBoot may have problems on 64X windows, then try:

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
