Are the lines like psychedelic herringbone? If yes, I had that happen once, it was something serious, like the
Logic board. The good news is that it was fixed without any loss of data on the hard drive. Take it in to have Apple look at it ASAP. I took it to TekServe at the time, they are very nice about preserving your data and user library when possible.
Good luck and don't panic.

I don't think my computer is completely shutting down. I think it is only going into sleep mode. When I hit the power button, it turns off immediately instead of shutting down.

I don't think my Mac Pro is completely shutting down. When I hit the power button, it just turns off immediately instead of going through the normal shut down procedures. I heard that I should try resetting the SMC, which involves removing the power cord. However, when I remove and replace the power cord, it turns on automatically, so I can't even properly reset that to see if it is the issue. Is this probably a power supply issue?
Actually, in case this information helps... The computer went into sleep mode the other day, and would not come back. This is a work computer that I use for our photography business, and at this point I am just trying to run it as a drive to get the photos onto our new computer, but this issue is keeping us from doing so. Any help would be greatly appreciated!

Try a SMC reset.

HT5587 Power button to turn off phone not working.... Help!

Power bottom to turn iPhone off does not work. Screen will turn off after a bit of no activity, but power off function when pressing does not work. Any ideas for repair? Thank you.

Assuming your warranty has expired you can make a Genius Bar appointment at your nearest Apple Store and do an out-of-warranty replacement for $149. Or use Google and find a local 3rd party repair site.

Any apps for screen off button ,without using power button? Similar to screen off for Android phone?

Any apps for screen off button for i phone 6 plus ,its convenient as i phone 6 plus is big and not convenient to use power button to turn screen off.Andriod phone does have this apps call "screen off"

After again experiencing problems I took the iMac back to the reseller where I bought it. They were able to replicate the defect and I received a new logic board. The invoiced cost (covered by warranty, luckily!) was $1,067 for the logic board and $85 for labor. The hard drive was erased but OSX Tiger was pre-installed when I picked up the computer. (BTW, Backup 3 is a very nice backup utility!) Now my iMac seems to be working perfectly, and the energy saver/sleep function works normally again.

Power mac G5 turns on but will not boot up

Hello,
I have the last power mac G5 quad core made before apple switched over to intel. I have not used he computer in about 3 month and it worked fine when I put it into storage but when I tried to turn it on today it will not boot up.
There is constantly a yellow light on near to where the RAM snaps in even when the computer is off. (this is the 3rd light up from the bottom and the only on that is on at this point)
When I press the power button a red light turns on for about one second. Next to this light are the words LED806 Checkstop and it is offset to the right of the other lights a little bit when looking into the side panel of the computer. This light also lights up briefly when I press the power button to turn off the computer.
After pressing the power button another red light turns on just above the yellow light that is always on and the screen is still black. Then the screen eventually turns grey with the apple logo as it normally looks except some of the pixels are off colored a bit in square patterns across the screen. When this happens a green light turns on just below the yellow light. Now there are three lights on all at once.
Next the screen briefly turns light blue and then a little darker shade of blue and the computer will not boot up or go any further than this point.
Can anybody tell me what is going on here and is there any way to fix this?
Is there any way to reset or reboot the computer this the install disk?
Distortion on the startup screen (hard to see in this photo)

Hi Mike,
LED 1—CPU A: red—contact Apple or an Apple Authorized Service Provider
LED 2—Overtemp: red—contact Apple or an Apple Authorized Service Provider
LED 3—Power On: red—the main power is on
LED 4—Trickle: yellow—Power Mac G5 is plugged into the wall correctly
LED 5—Open Firmware good: green—no problem
LED 6—CPU B: red—contact Apple or an Apple Authorized Service Provider
LED 7—Checkstop: red—contact Apple or an Apple Authorized Service Provider
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

I did a factory reset on my late 2008 MacBook from a Snow Leopard disc. It installed fine, but as soon as I began to use the computer (safari) it froze. Couldn't even force quit. So I held down the power button to turn it off, and now it won't start up.

So I held down the power button to turn it off, and now it won't start up. It goes to the grey Apple screen and just sits there loud as can be. Help! Please keep in mind I've not done anything like this before and am going to need a little hand-holding. Thanks in advance.

Hi. Don't worry it's nothing serious. Insert the Instal Disc (Snow Leopard) and press the C button while turning on the computer. Once you see the desktop, go to Utility and choose Disk Utility. Select the Macintosh Partition on the left window pane and then click on Repair Disk and Repair Disk Permissions on the bottom right corner. Wait for both processes to finish. Click on the Apple icon (top left corner) and choose quit. Your computer should restart. See if it reboots normally. If not you can always reinstall the OS following the same steps. Good luck!

I have a mid-2011 iMac running Mavericks. When I click restart the computer goes to a white screen with a spinning circle and does not go any further until I hold down the power button to turn it off. What do I do?

Ok, sounds like the safe mode boot worked... You probably don't want to always be in safe mode though (some reduced functionality) so does it do a normal boot now? If not, you should then reboot into safe mode and run Disk Utility. Then select Macintosh HD on the left hand side, and click the Verify Disk button. If needed, it will ask you to Repair Disk. If there are errors found, Repair Disk again until there are none. Then try another normal boot and reply with result, wether good or bad.

Grey screen with message "turn off computer with power button until switch off then press again power button"

Dear all,

I try for two weeks to restore my iMac without any success...
I wait 80 hours to finally have the message again and again : "to restart your computer : turn off computer with power button until switch off then press again power button".
But my iMac do not work !
Could you help me?

Hello, that's a kernel panic...
http://thexlab.com/faqs/kernelpanics.html
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X 10.6 Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

my phone just turned off and will not go back on. my top lock button has been broken for over a year. Help! I have tried plugging it into wall unit and computer but my home button just doesnt do anything!

It seems that year long delay from having your lock button repaired has finally caught up to you. Sounds like you have some damage to your phone that requires repair/replacement. Take it to a Apple store or contact Apple Tech Support.

How absolutely turn off computer if I use lilo boot loader?

How absolutely turn off computer if I use lilo boot loader?
With this /etc/lilo.conf content computer not absolutely turn off:
# /etc/lilo.conf
boot=/dev/hda
# This line often fixes L40 errors on bootup
# disk=/dev/hda bios=0x80
default=arch
timeout=0
lba32
prompt
image=/boot/vmlinuz26 append="apm=power-off"
label=arch
root=/dev/hda1
initrd=/boot/initrd26.img
read-only

Please provide some system specs so that we may give better advice. As phrakture has already said, you must have hardware that supports power management before auto shutdown works.

A black see through screen slides down from the top of the Mac and tells me to switch off using power button. Nothing works other than just that. I run sophos up to date and use Safari. Everything is up to date. My Mac is a 21" and is three years old.

As per title. Twice in a few hours. Happened each time when my BT router defaulted to plain public wi-fi and while I waited for airport to locate my router hub I just ticked my hub and boom this dark almost black see through screen slid down and instructed me to switch off using power button. It is a 3 year old desktop 21" and has been faultless until this. I get the default report an unexpected shutdown form and when I fire up it is fine as indeed it is now.
Any help or ideas how to deal with?

I have an iphone and i was sending a multimedia message and all of a sudden the phone turned off and will not turn back on. We have been charging it for almost half an hour or more and it still hasn't turned on. How do we fix it?

Wine, were you charging over the USB Connection or AC Power? We've found in our organization that at times not enough power is generated over USB to recharge it in situations like this...I quote from the email of a fellow technician that i just received today...
I’ve had a couple of users up here bring their iPhones to me so dead that the phone was unresponsive, no matter what we did. One thing that many people do not realize is that the iPhone (iOS devices in general) have power management in them. The power management appears to be set up so that the device will not power on at all until the battery is at a certain minimum level. If the user will plug the device into the power adapter, not a USB port on a computer (laptops especially), and leave it for about an hour, maybe longer, the device will come back to life.
The reason I say they have to use the power adapter is because the USB port is not high enough power to bring the charge up fast enough for the battery to come back out of “hibernation”.
Each time I have had the users do the power adapter plug in, and leave it for a couple of hours, the devices have come back to life
Hope this helps

How complitely turn off computer?

How complitely turn off computer?

Are you talking about where it shuts itself down after going through the shutdown routine? If it's not doing it automatically when you issue a "shutdown -r now" (or the like) then it's probably an issue with power management. There's a few ways to tackle that. Either use APM or ACPI. ACPI tends not to work all that great on computers that have really old bios. In that case it's better to utilize APM. Probably your issue is that the your system may not support ACPI very well or even at all. However, it may support it, but the kernel is turning it off by default from detecting your BIOS being dated beyond a certain point in time. They did that to error on the side of caution. They opted to choose a conservative default assumption since it makes more sense in that at least most systems will be able to boot up without any problems by default.
My computer used to be able to shutdown automatically through the use of APM, but not ACPI (ran into this issue when I upgraded my kernel from 2.4 series to 2.6 series back when I ran with Debian), but I ended updating it's BIOS and it worked fine with ACPI from there on. My system is pretty old too, so it doesn't completely implement ACPI. I think it's laptops that tend to make fuller use of ACPI anyway. However, it seems like most desktops with the last 8 or so years make some minimal use of it at least. So you can see there is many ways to approach this issue.
First thing to try is to look around in your BIOS setup to see if there is any ACPI related setting, like mentioned earlier. That's a good place to start. If you don't see any settings, it either means that your BIOS setup either don't allow you to set ACPI, doesn't support it, or just the current version of your BIOS doesn't allow changing related settings or make use of it. So naturally, the next thing to check is the manufacturer's sight for your motherboard and find any BIOS related info.
Upgrading the BIOS is probably the most elegent solution but it can be openning up a whole can worms if you don't know what you're doing. If you botch flashing the BIOS you run the risk of turning your motherboard into a paper weight. So the key there is make sure you at least read your manufacturer's instructions carefully and also make sure that your use the right utils and BIOS version for your BIOS and motherboard. And don't dare have a power failure or shut the system off while it's rewriting the boot block. That where people run into a serious problem of rendering their system completely unbootable since the system no longer has the most basic of code needed to even get the system to a state that it can even begin bootstrapping. Technically, the motherboard isn't probably trashed, but at that point you have a chicken before the egg syndrome going on. You can't get it to boot far enough to boot to anything, much less a floppy, to be able to reflash the bios to get yourself out of the pickle. So when, and if that sort of thing happens, then it would require replacing the BIOS chip itself which may or may not require soldering.
Anyway, don't let that scare you, it's just to point out that when you're doing things like flashing a system's BIOS it's critical to do it right since it's modifying the system on such a fundimental low-level. If that part of the system isn't functional, everything else, like HD and floppy being able to load anything, is a moot point.
If all of that stuff makes you uncomfortable, you may opt to utilize APM instead. I can't remember exactly how to instruct the kernel to use APM instead of ACPI. I believe there is kernel parameter you can set in your bootloader's settings. I can't remember it off hand. Sorry.
