I am trying to get my Dad's computer to turn on. It's a 17" IMac that was bought around 2007. Today it just won't turn on. When u hold the power button down, the white light comes on in the lower right hand of the computer but screen stays dark.

It have tried pulling cord out if the computer and then plugging it back ...it still won't turn on. Pls help...next step

Try using the resetting SMC procedure
http://support.apple.com/kb/HT3964
You may have done something similar already, but do it precisely as described. You should disconnect ALL peripheral devices, except for Apple keyboard and mouse.
Also, when you plug it back in, if the iMac is currently plugged into an old (or overcrowded) power strip (surge suppressor), try connecting it directly to a wall outlet by itself.

My macbook pro won't sleep - if I select sleep it does so initially, then the disc-drive appears to kick in and it comes back to life. It also won't turn off (again, the disc drive kicks in) unless you hold the power-button down for a long period.

Macbook pro 2010 only will turn on if i hold the power button down for atleast 7 seconds.....before i could just press it and it would come right on

I tried those already, did not work.
I did how ever remove the command key and wiped it down and it turns on perfectly!
but now the keyboard keys seem to be out of place or something. For example it makes a "ping" sound when i hit some of them, when i hit function or control it puts the letter Z.
Any input would be great!

I have a mac book pro running Lion 10.7.4 and every time I use Google Earth The computer crashes by lowering a black curtain and then asking me to hold the power button down until it closes and press the power button again to restart it. Can I fix this?

I have a mac book pro running Lion 10.7.4 and every time I use Google Earth The computer crashes by lowering a black curtain and then asking me to hold the power button down until it closes and press the power button again to restart it. Can I fix this? It bugs me when I'm looking at real estate.

I really don't have an answer for that one. I guess that while trying to get things working correctly, I would use the most basic monitor I had which in your case would be the Eizon using the Thunderbolt port and adaptor.
When you boot into Safe Mode the startup is quite slow, but you should get the Apple logo and then the spinning gear below it (release the SHIFT key when it appears.) Then after a little more time you should see a gray progress bar appear below the spinning gear. When that disappears the computer will startup to a login screen.

After a few minutes on safari it freezes everything i can't even force quit i have to shut off by holding the power button down please help me with this. thanks

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Macbook wont powerup, beeps repeatedly when power button is pressed and you need to hold the power button down to shut the beeping off. any thoughts?

Have a 13" macbook. wont power up. upon hitting power button, the computer sounds 3 long beeps constantly until you hold the power button down for 5-10 seconds. any thoughts out there?

Thanks guys, i just read a few articles regarding this. i pulled all the ram and tried swapping and reseating ram. it appears both chipsets are fine but one ram slot is bad. computer will boot with either chipset installed in the one good slot but neither chipset will boot in the other slot. bummer....

No. You need a computer with iTunes and an internet connection.

It can not able to check warranty of my iMac that was bought 1 month ago. I don't know what the reason is?

It always ask validate the purchased date. But when click there, it request serial number again, i entered my serial number then it ask validate purchased date again. It is a loop.

Contact AppleCare, they can advise how to assist. If you have not purchased AppleCare and the computer is still in warranty then I strongly recommend that you do buy it, this will extend the warranty from 1 year to 3 years and provide 3 years of telephone support.

Apple Store currently thinks it's a hardware problem

My Power Mac G5 is freezing up. A few days ago my G5 started freezing up, the cursor is unresponsive and none of the keys have any use. I have to press the power button to shut down and then restart. Sometimes on the restart, instead of the Apple logo I g

A few days ago my G5 started to freeze up while in use. It doesn't matter if in Safari, iTunes, Pages, etc. The cursor will not respond nor does any keystroke, force quit, escape, etc. I have to hold the power button down to shut the computer down. Then, try to restart. Sometimes restart will work and the computer will work for a while and then freeze again. Other times on restart, instead of the Apple logo at start up, I get a Zero with a line thru it, have to power off and restart again. When it does restart, the "spinning gear" takes a lot longer than normal to spin up and take me to the login screen. Have been told it may be my hard drive getting ready to fail. Have looked at disk utilities, S.M.A.R.T looks fine, "verified" and have verified disk, and repaired permissions. In case it is the hard drive, I bought external hard drive and hooked it up to Time Machine. The backing up to a long time, overnight, about 10 hours because it kept freexing up and I would have to shut down and try restarting again. Finally got everything backed up.
Any help or suggestions greatly appreciated!!! Could it be my hard drive is dying? Is the the normal chain of events or is it something else???

Ok, to copy the Drive from one to another, get carbon copy cloner to make an exact copy of your old HD to the New one...
http://www.bombich.com/software/ccc.html
Or SuperDuper...

Believe it or not, anything on the Desktop uses 3 times the Resources of the Mac than if stored elsewhere, I can note a slowdown from just 30 items on the Desktop on a really fast Mac, so the less the better on the Desktop.
DW will not tell you about Bad Sectors, it's just the very best at Repair Directory damage & such.
At this point I think you should get Applejack...
http://www.macupdate.com/info.php/id/15667/applejack
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 6 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.

My iphone 4 had went black and now it wont turn back on i was just texting a second ago now i tried holding down the power button and that didnt work i need help

my iphone 4 had went black and now it wont turn back on i was jsut texting on it a few mins. ago then when i went to check my texts it was black i tried holding the power button down but that didnt work can someone please help

Hi alicia243,
Thanks for visiting Apple Support Communities.
If your iPhone wont power on, I recommend going through these steps first:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Best,
Jeremy

How do you turn on the laptop when it shuts itself down and the power button isn't working

How to I turn the laptop on after it has shut itself off

If you hold the power button down for 15 to 20 seconds and the machine still will not turn on, you should do one of three things:
1. Take it to an Apple Store for an assessment and estimate.
2. Take it to an Authorized Apple Service Center for an assessment and estimate.
3. Consider purchasing a replacement machine.

I am trying to get my Dad's computer to turn on. It's a 17" IMac that was bought around 2007. Today it just won't turn on. When u hold the power button down, the white light comes on in the lower right hand of the computer but screen stays dark.
