HELP please... iPhone won't start or turn off. Apple logo only

I try to reboot the phone w/by pressing the button on top and the button on the bottom of the face of the phone. The phone will go dark then come back w/just the apple logo... it goes no where else.
HELP

Known issue (better to say known quirk, not issue, however Apple should document it.) When you force boot the phone while it is loaded and running you corrupt some database and next boot will take a long time to rebuild this information. My 32GB 3Gs can take up to 7-8 minutes to boot as I have it full of music and I think it's rebuilding the music database during this long boot startup. The situation you are in now is that you have to wait for it to finish booting. The best way I have found if you phone is not stuck is to push top button until you get Red slider to turn off, slide it and allow phone to power off itself. Once off, Hold Top button and Home buttons, Keep holding them, you will see Apple logo pop up, KEEP HOLDING BUTTONS, do not release them until Apple logo goes away. If when you release both buttons the phone starts up and you see the Apple logo you have not held the buttons long enough as it sometimes will need to cycle down twice. When you have it right, when you release both buttons the screen will stay black and phone will not auto-power up. In this state the phone is fully off, not in standby. If you have previously powered the phone off gracefully with the top-button+swipe then hit top button for a couple of seconds and Apple logo should appear and phone should boot within a minute and be ready for use. If you cycled the phone without first gracefully shutting down, the bootup process can take much longer, give it at least 10 minutes before giving up. I have not found this documented by Apple anywhere, I found it from trial and error. My wife has 16GB 3Gs and while playing with both I found this out. Hope it helps you.

HT1766 iphone won't start up. keep getting apple logo

Trying to get Iphone 4 to start up. Keep getting logo. Have to plug it in to get it to the home screen. I can not unplug it or it shuts down. When home screen does come up it won't find service. Wifi won't turn on either. Any sugestions

Put the phone in recoverty mode and restore the iOS as described in this article:

Computer won't start, grey screen with Apple logo only. Ideas?

Last night my wife's G5 froze. It is a G5 2.0 running OS X 10.4.11. I shut it down (had to use the power button) and tried to restart. No luck, just made it to the grey screen with Apple logo and spinning wheel. After a few seconds the Apple logo disappeared and a black box took its place, then the wheel stopped spinning. It was late, decided top wait until morning before trying again.
This morning I tried to start up again. This time got a warning(?) in upper left that a Firmtek item had already started. I'm sorry I didn't write this all down at the time, so I don't remember the entire message. Since there is a Firmtek card installed in one of the PCI slots I thought that might be the problem, and I pulled the card, as well as another Adaptec card that was also installed. Tried to start again, got to grey screen with Apple but this time no spinning wheel.
Opened media slot manually and inserted Diskwarrior. Tried to start with Diskwarrior but again only reached grey screen. Let run for ~5 minutes, until fans started to run and were begining to get noisy.
Next I reset the PRAM. No luck, still stuck on grey screen. Tried Diskwarrior again, this time got another message in upper left. Here is most of it -
System Failure : cpu=1; code=60000009 (Invalid pmap)
Lateset crash info for cpu1;
Exception state (sv=0x609bb280)
PC=0x000a4ad0; MSR=0x02003000 followed by more similar strings, then
backtrace terminated - unaligned frame address; 0xfc088891
So what's the diagnosis? I've had various issues with my G5s in the past, but have never had one refuse to boot with Diskwarrior before.
Thanks in advance for any help!

Whew, could be many things, from RAM, (or RAM slots/solder issue), to CPU #1 being bad, (CPU#1 is actually the second one.
Does it boot into any of these modes?
Target mode...
http://support.apple.com/kb/HT1661
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

We might get clues with verbose mode...

My iPhone 4S has started to turn off before its out of battery. There is no pattern it is completely random so I don't know when it will turn off, when I try to turn it back on it says it needs to be charged.

As soon as I plug it in to the charger it reboots to the same percent it was originally on before it turned off for example today it turned off on 10% I tried to turn it back in and it said out of battery so I plugged it in to the charger and it immediately rebooted showing the apple logo and the phone was on 10% when it was fully rebooted.
I was wondering do I need a battery replacement or is this something more serious.
Many thanks.

Hi Lukeohiggins,
If you are having issues with your iPhone unexpectely powering off, you may want to try the troubleshooting listed under Power/Battery > Will not turn on, will not turn on unless connected to power, or unexpected power off in the following article:

OS X won't start; stuck on the Apple logo

I went out of town on Friday and shut down my iMac G5 (Intel, purchased brand new January 2007). When I got home today and tried to boot it up, it stuck on the grey screen with the Apple logo and spinning gear. It will stay there until I either unplug my iMac or hold down the power button until it shuts down. This happens every time I attempt to boot OS X. I try to start in Safe Mode (holding down shift), but get the same result, same when I unplug all peripherals. I can, however, boot Windows XP via Boot Camp, which is what I am using to access the internet right now. Everything seems to be working perfectly in Windows XP, but it won't boot at all in OS X. I don't have access to my Install disc right now (It's at my dad's house; we got the family version of Leopard.), but I could get it if I absolutely have to.
Any suggestions? Thanks.

Your problem may be different, so it might serve you better to start your own thread. That said, both problems occurred when switching locations, so I wonder if the network/wifi might be involved. However, Niels, if you are unable to start at all, with any of those methods, there may be something more serious involved (we have had no feedback from the OP in the last few hours).
Showing the last screen suggests a total (and unusual) freeze with the computer not having shutdown or gone to sleep. Did you close the lid and leave it? If you cannot start with the disk or with the Option key it is not simply the OS gone awry, IMO.
Last resorts?
One thing not tried is to hold down the Command, Option , P , and R keys on the keyboard to reset PRAM.
Also, as a really last resort, hold down the Command, Option, O, and F keys. A grey screen will appear with a command line. Type +reset all+ and if that does not work, it is off to the shop.

IMac won't start up - just have apple logo plus 'processing' symbol active?

Unable to start computer.

I work at an Authorized Apple Reseller and we are having the same problem with one of our showfloor models.
Model: iMac 21.5" (Brand New Core i3, etc)
Problem Description: When you press the power button, you hear the Apple chime and the screen turns on. Instead of booting normally, the screen shows the Apple logo, a spinning 'loading' circle (I call it a ferris wheel), and a loading bar below that. Typically the loading bar is for an EFI Firmware update, but I don't remember updating the iMac recently. Anyways, the loading bar moves once, starts over, and then the iMac shuts down.
Possibly Related Issue: Several days leading up to this issue, the computer was very noisy. It sounded like the hard drive was working overtime on indexing or something, but it ran fine and spotlight wasn't even indexing at all. I walked by it yesterday and noticed it wasn't on. I pushed the power button, and the problem it has now started.
I will keep searching the forum for a solution, but I have a feeling this is a hardware issue that will need to be serviced by Apple.
Sidenote: If anyone has any experience contacting apple as an Apple Reseller about repairing a computer before the warranty starts, any advice would be greatly appreciated

HELP PLEASE ! ! How do I delete the Apple logo from the menu screen?

I need a blank opening screen without any animation and my client doesn't want the apple logo. How do I get rid of it and do I start with a nice clean screen with just the name of my client's company?

Hi there. Go to the iDVD menu, then preferences. You can untick the option on the General tab for "Show Apple logo watermark" and it will disappear Simple! (when you know how)

HELP please: iphone won't open in itunes running OS X 10.5. so cannot get iTunes 11.1.3

My iPhone 4s with 7.0.2 will no longer open in iTunes! HELP!
It says that I need to upadate my iTunes to 11.1.3 but because I am running a Mac OS X 10.5.8 I cannot update my itunes.
I need to be able to get into iTunes and I am not willing to get a new computer to do this! HELP!

Buy Snow Leopard from the Apple store. It's your only choice.
Or you can install Windows and download iTunes…

Original iPhone won't sleep or turn off

The unit seems to function fine (apps, calls, voicemail) but after twenty seconds in sleep mode, it wakes itself back up for twenty seconds, then repeats. When coming out of sleep mode, it flashes what looks like a text message box for a fraction of a second, too fast to read. I've tried to turn it off completely but when I do it automatically turns itself back on. This is the 4G model.

I had the same issue with my iPhone 3G, and -- purely on a hunch -- fixed it by draining the battery completely (until the iPhone turned itself off). I then charged the iPhone for about 10 minutes (only so I could turn it back on), and then tried turning it off (using the "slide to power off" feature). This time it stayed off. I have tested it a few times since, and so far have not come across the same problem again.
A quicker way of draining the battery would be to turn up your brightness all the way, turn on push email/location services/3G (if they are not already on), and start a photo slideshow to accelerate the battery usage (and possibly prevent burn-in).
Hope that helps.
PS Do any of you use a third party sync cable? (such as a Griffin Powerjolt USB cable.)

Turn off Apple logo light at the lid

I just got my macbook today... Thinking of saving some battery life, can someone enlighten me on how to switch off the light of the Apple logo at the lid of my macbook.
Thanks.

You can't the Apple is lit when the screen is on. They share the backlight of the screen so it uses no extra power.

My iphone 3gs randomly started to turn itself on and off today and it won't stop like it is continuously doing this. I haven't dropped it or anything it just randomly started doing it. I put it in rice just in case it got water on it. Help! ?

My iphone 3gs randomly started to turn itself on and off today and it won't stop like it is continuously doing this. I haven't dropped it or anything it just randomly started doing it. I put it in rice just in case it got water on it. Help! ? My phone won't even be a year old until next month and I was really wanting it to last me for 2 years. :/ What should I do?

Took my phone to the Apple store this week and they told me it was a hardware/screen malfunction. They replaced the screen for free since it was under warranty. Now it works fine again!
