Computer won't turn on

Put computer to sleep last night and when I attempted to use it this morning, it was off. When I press the power button, the light on the front flashes on for a moment (just a split second) and then turns off. Can't get the computer on. I didn't have time this morning to mess around with the power strip, but could that be the problem? Anyone else had a similar issue?

Well, I took my iMac down to Small Dog yesterday and it ends up that I have a bad hard drive like I suspected and that I also need to have the logic board replaced. I almost expected that as well as my serial number falls in the range of iMacs eligible for the repair extension program. On the bright side it should be fixed by tomorrow but since it's an hour away I'll probably go down on Thursday and take the day off.

How can I transfer my iTunes data from one computer to another? PS. My old computer won't turn on

I Recently bought a new computer and I need to transfer all my iTunes data from my old computer to the new one, how can I do that? And by the way, my old computer won't turn on

Hello Nousernamebrah
Well get get your music from your old computer to your new computer, the old computer would have to work and turn on to access the files to be copied over. You also can access any previous purchased music and download it to your new computer as well. Check out the articles below for more information.

My mac desktop computer won't turn on how can I know what's wrong with it?

It won't make the start up noise at all. Also the screen won't light. All I hear is a click noise when I click the power button. I've tried connecting it to other power outlets yet it still won't work?

Computer won't turn on and the power cord doesn't light up

My problem with the computer is that it will not turn on. The battery is fully charged, power cord is plugged into a working outlet. I have held down the power button for 10 second or even longer. Nothing turns it on and the power cord doesn't light up at all. Any thing will help.
Thanks

First, check that your AC outlet has power. Second, see this article: Intel-based iMac- What to do if your computer won't turn on and this one Resetting MacBook and MacBook Pro System Management Controller (SMC).

Computer won't turn on HELP!

Hi,
My computer won't turn on after a few hardware swaps I did.
Parts :
MSI Z77 Mpower, i5 3570k @ 4.0 Ghz, ATI HD4870, Gskill sniper low voltage 2x4gb 1600Mhz, Samsung 840 series 256gb (os), 2x ST4000DM000 (raid 1).
So here's what I did. I shut down the computer, I disconnected every wire with caution to wait for CL_CMOS LED to turn off before pulling the cord. I then switched my ram for Gskill Ares 2x8Gb 1866Mhz (occupying DIMM slots 2 and 4, same ones as my previous ram sticks) and switched my GPU for Asus R9 280x DCUII.
I reconnected everything, CL_CMOS LED powered on. When I pushed the power button, nothing. I pushed and pushed again but nothing happens. I noticed that CL_CMOS LED turns off after I try to push the ON button on my case. When I switch the power off, the LED remains off until it flashes briefly and turns off again.
I've tried putting my old parts back in 1 by 1 but it won't turn on again.
Please help!
edit : old ram timings (CL9-9-9-24, 1.25V) new ram timings (CL10-11-10-30, 1.5V)
edit2 : The lights on my new gpu's pcb were lit during this struggle. Power could come from the pcie adapters though.

As in Reply #1, keep that configuration and use the switch on the mainboard over to the other BIOS chip. For some reason, it sounds like the one chip may be corrupted or maybe the PSU has become faulty. Double check the security of the 24-pin and CPU power 8-pin connections.
Thanks for your help. I fixed the problem. I am a bit ashamed to say what was wrong but ... the 24 pin connector was loose on the psu side.
I figured it out after 2 days of disassembling/assembling computer and testing components.
Thanks for your help.

Battery won't charge, computer won't turn on

My battery won't charge, even though the power adapter light is on as if charging. I've tried using other power dapaters of the same model, with the same results; no charge. Now the battery is dead and the computer won't turn on. Should I just get a new battery?

I tried resetting the PMU, before the battery totally ran out. Now I'm sure the battery is totally dead, but not sure if it will charge once I get a new battery. Looking at other postings, it sounds like the problem could be with the logic board.

The CRT won't come on and the computer won't turn off. ???

Hi all,
I just got another free Rev. A iMac CRT today - it was in an old, abandoned school and the people who were moving everything out of the school thought it was dead, so they gave it to me. I tried starting it up, and it wouldn't turn on. When I took off the back to see if it had any good parts in it, it turned out everything was unplugged in the back, so I plugged it all back it. It worked great, I was deleting the school's files and apps so I could sell it, until a few minutes ago when I tried to wake it up from sleep. The display just wouldn't come on. I though it just wasn't waking up. I tried typing on the keyboard and clicking the mouse, and I finally pressed the power button on the keyboard, when I heard the normal beep it makes when you press the power button on the keyboard and it gives you the dialogue box "Do you wanna turn it off, restart it, etc?" I thought, "this is weird, why isn't the display on?" So I pressed the enter key, figuring that Turn Off was the option selected and that the display would come on when I turned it back on. Sure nuff, the computer turned off. I waited a few seconds and turned it back on. The display still wouldn't come on. I waited a few minutes til I was sure it was all the way booted up. It won't respond to the keyboard, the mouse, repeated jabs in the reset button on the side, or the power buttons on both the unit and the keyboard. I held down the power button for an entire minute and the display won't turn on and the computer won't turn off.
This is totally bizzare. Does anyone know how to a) turn on the display or b) turn off the computer? It's looking like I'm going to have to unplug it and try again later.
By the way, it's running 9.2.2, like the one in my signature line.

I finally pulled the plug and restarted and it's working fine now. Does anyone know what happened? I think it could've had something to do with the PRAM battery; every time I've started it up it's said the date is January 1956 and the time is 9:55. hmmm...
Edit: I just realized that in addition to the date being 1956, the hard drive was completely randomly renamed to "k hortdpc." ***???
Another edit: I just realized I probably renamed the hard drive in my frantic random clicking and typing - I probably accidentally clicked the hard drive name and randomly typed a new name in my attempts to wake up the computer. oops

TS1367 Computer won't turn on. It's plugged in and tried to turn it on. Any help please.

Computer won't turn on. It's plugged into an power outlet and the power light no doesn't turn on and the power lights no longer show up. Can someone please help?

Take it to an Apple Genius Bar or an Authorised Apple Repair Centre.

My computer won't turn off. It says iPhoto is doing something and iPhoto is doing nothing, the circle has been spinning for 45 minutes.

My computer won't turn off. It says iPhoto is doing something and iPhoto is doing nothing, the circle has been spinning for 45 minutes.

Try that. If that doesn't help:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

My computer won't turn on (display). I hear it "on" but nothing. I have removed battery...turned off and on. What could it be

my computer won't turn on. I have removed battery and turned off and on. I can hear the drive and fan. But the screen is blank.

I'd suggest making an appointment at your nearest Genius Bar - they would be able to diagnose it (free) and then you'd know if it's a hardware issue.

I spilled a little bit of soda on my keyboard ( more like big drops) and my computer won't turn on but it will still charge. After i spilled it it kept trying to turn on and off by itself until i finally just shut it down

I spilled a little bit of soda on my keyboard ( more like big drops) and my computer won't turn on but it will still charge. After i spilled it it kept trying to turn on and off by itself until i finally just shut it down. Today i tried to turn it back on ( i spilled it last night) and now it won't turn on but when i plug it in the orange light comes on so it still charges.

TBF: You may have been lucky enough not to cripple your MBP immediately with your spill, but a spill such as you describe will have left obvious traces if you ever need to take your machine in for a repair of any kind. And as soon as evidence of the spill is found, any chance of the necessary repairs being performed under warranty will be gone.
Taking the machine in now to be cleaned and have the greasy parts replaced will be expensive, but doing so may save whatever remains of your warranty. For a price, Apple will restore the machine to like-new condition, and at the very least, you will then have a 90-day repair warranty on it. If you have significantly more time than that remaining on your original one-year warranty, and especially if you've bought the extended AppleCare Protection Plan, it would probably be worth taking the machine in to a Genius Bar for a look-over. Ask whether, if you have Apple clean and repair the machine now, your new-computer warranty and AppleCare plan will be reinstated afterward or whether all you'll have is the short repair warranty from now on. If the spill will negate your warranty and AppleCare even if you have Apple clean it, then the cleaning probably isn't worth paying for. But if paying for the cleaning will get your warranty and AppleCare reinstated, it may be worth doing.

HT1349 My computer won't turn on. Makes a low beeping noise that I've never heard but the screen doesn't turn on. The battery ran completely out but I've had it plugged in for 2 hours. Any thoughts?

I have a MacBook pro. After running the battery down, the computer won't turn on. It seems to cycle on but then makes low beeping noises and the battery indicator light blinks along with the beeps. I've had the computer charging for quite awhile. Any thoughts?

UPDATE:
My computer now works but still has the loading bar at startup. Here is some advice for other mac users with the same problem. To get the computer to turn on again (but unfortunately still have the loading bar - you will need to fix this problem seperately) follow these instructions:
Shut down the computer.
Unplug the computer’s power cord and disconnect peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
This is called a SMC Reset and will hopefully get your computer back up and running (at least for the time being!)
Good luck to all those iMacers out there!

2006 iMac Desktop computer won't turn on?

     My Mac desktop computer from 2006 won't turn on. I tried unplugging it and re-trying and that didn't work. Does anyone know why this happens and how I can fix it?
     One time, we brought it in to the apple store and it turned on there so they didn't fix it. Sometimes it turns on randomly after a lot of tries, but now it hasn't turned on for a while. Usually we leave it on, but we had to turn it off because the power was about to go off.
     Thank you!!

Hopefully something here will cast some light:
iMac G5: Fails to startup
http://support.apple.com/kb/TS1989?viewlocale=en_US

My computer won't turn on. When the charger is plugged in it flickers between yellow and green

I was using my MacBook pro felt it charging and asleep for 4 hours. I came back and it won't turn on. When the battery is plugged in it flickers between yellow and green.

First thing to try would be resetting the System Management Controller. If that doesn't fix it you are probably looking at a hardware issue. Carry the computer in to an Apple store or service provider, or call Apple to set up service.
Best of luck.

Computer won't turn on after Panther installation

I installed Panther successfully on my iMac G5. After I hit "restart" the computer is stuck on gray and the wheel is turning but the computer never completely turns on. I have forced it shut and tried numerous times to restart the computer but it continues to do the same thing. Any suggestions on how to get the computer to start? Perhaps it won't start because the installation DVD is still in the computer. Is there some way to manually eject the DVD without the computer being turned on?

You may be right about the disk thing. Hold the mouse click down on startup, until the DVD is ejected.
If that fails, zap PRAM. Hold down optcnd+RP on startup, and listen for three bongs before you let go.
