Flickering between password screen and apple logo?

my ipad 2 keeps flickering between the password entry screen and the apple logo on a black screen every second, bleeping as it switches between the two screens. This will go on indefinitely and no individual button is receptive, for example you can not alter the beeping volume.
I have left the ipad until the battery drained, but when placed on charge it starts going through the same process, flickering between the two screens. I have tried holding the home and power down buttons in as suggested on these forums but although it reboots as such it starts to beep and flicker between the two screens.
Has anyone any clues, the beeping is getting a little annoying.

Yes, it concerns me a little as well. Make sure you are running the latest version of iTunes and you could try uninstalling and reinstalling iTunes. That may be the issue causing iTunes to think that the iPad is an iPhone.
Before you try that, try different USB ports on your computer. Don't use a hub. Make sure you connect directly to the computer. You could try rebooting your computer as well.
Here are instructions to remove iTunes.

I know you feel this way too, but I don't want your situation to get any worse with trying too many things. I know you are "dead in the water" anyway with the iPad but still - you don't want to exacerbate the problem.

Hey kathlovesparis,
First, I would reset the device:
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.

And if that doesn't resolve the issue then I would backup the device to iTunes and restore it. Just be cautious and back up first, since restoring deletes all content and settings:

My MacBook Pro shuts down within seconds after starting with a Gray Screen and Apple Logo, a bar comes at the bottom.

My MacBook Pro starts with a Gray Screen and Apple Logo, a bar comes at the bottom, but after few seconds the machine shuts down. This was bought approx 1 year back. Please help!!

jayanta.ray,
which model MacBook Pro do you have (did you buy it new?), and which version of OS X is installed on it?

Recently when clicking on Safari, it refused to open saying there were some components damaged. It was suggested I backup, remove OSX and reinstall. Now all I get is white screen and apple logo when starting. What to do?l

I Have an iMac desktop purchased in 2010 with OS X 6.1.6 and Snow Leapard. Recently after starting up, I was not able to open Safari. I checked for updates and all was well. I tried again and got a message saying Safari could not be opened because some components were damaged. After using Disk utilities to try and repair, it was suggested I uninstall OS X and reinstall from the disk. I did not at the time because I wanted to backup some info to a USB drive. But now when I startup all I get is the white screen and Apple logo and the loading symbol. What happened and How can Imfix it? I am not very tech savvy and don't know where to turn!

Hi nancy mfromamity harbor,
Welcome to the Support Communities! It sounds like reinstalling the Snow Leopard operating system is your next step. This should not affect the documents and data that you currently have on your iMac. I'll include the information to show you how below.
Mac OS X 10.6: Reinstalling Mac OS X
http://support.apple.com/kb/PH6606
Under some circumstances, you may need to reinstall Mac OS X. You can reinstall Mac OS X while keeping your files and user settings intact.
Note:To reinstall Mac OS X from another computer on your network, see:
Using another computer’s DVD or CD drive
To reinstall Mac OS X:
Insert the Mac OS X installation disc and double-click the Install Mac OS X icon.
Follow the onscreen instructions. In the pane where you select a disk, select your current Mac OS X disk (in most cases, it will be the only one available).
If you want to control which parts of Mac OS X are installed, click Customize, and then select the parts you want to install.
To start the installation, click Install.
If you purchased a standalone version of Mac OS X, these installation instructions are in a PDF file located on the Mac OS X installation disc.
If you need to reinstall the version of Mac OS X that was on your computer when you purchased it, or if you need to restore all the software on your computer (including Apple software, third-party applications, and other printer drivers), refer to the documentation that came with your computer.
If you need to reinstall Mac OS X and you’ve been using Time Machine to back up your applications, files, and user settings, you can easily restore this information from your Time Machine backup disk after you’ve reinstalled Mac OS X.

My IPad Air is frozen with a white screen and Apple Logo on it.

My Ipad Air is frozen with the white screen and apple logo. I've tried resetting it several times and that doesn't help. I tried connecting to ITunes, but it isn't recognizing the device.
The battery is fully charged, at least for now, so I am not sure what else to try.

FORCE IPAD INTO RECOVERY MODE
1. Turn off iPad
2. Turn on computer and launch iTunes (make sure you have the latest version of iTune)
3. Plug USB cable into computer's USB port
4. Hold Home button down and plug the other end of cable into docking port.
DO NOT RELEASE BUTTON until you see picture of iTunes and plug
5. Release Home button.
ON COMPUTER
6. iTunes has detected iPad in recovery mode. You must restore this iPad before it can be used with iTunes.
7. Select "Restore iPad"...
Note:
1. Data will be lost if you do not have backup
2. You must follow step 1 to step 4 VERY CLOSELY.
3. Repeat the process if necessary.

HT1199 my computer displays grey screen and apple logo for 10 minutes or more during start up and shut down. sometimes it refuses to shut down . this issues started after installing OS lion. what do i do?

my computer displays grey screen and apple logo for 10 minutes or more during start up and shut down. sometimes it refuses to shut down . this issues started after installing OS lion. what do i do?

I don't think it's exactly an incomplete installation brody, but most likely in-correct permissions somewhere along the line that either happened, or became magnified during the upgrade. Also, it could be corruption as well.
First thing to do, is boot up holding down Shift key to do a safe-boot so we an clean up any corrupted OS caches, after that do another reboot, but go to the Lion recovery, and scan the HD for errors, repair any if you find them, and then try to do a Repair Permissions job.
That should fix the issue, if not, we can start doing a PRAM reset and SMC for good measure.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in 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.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

Mac won't go past the white screen and apple logo

My one year old mac won't turn on, it comes up with the white screen with the apple logo, after a few seconds a loading bar comes up and after it finishes loading the mac just turns off. When I turn it back on it just does the same thing. I tried resetting the pram (it even chimed twice) but it still did the same thing. The problem began with the power cord being accidentally unplugged, when I plugged it in and turned on the mac the grey screen came up asking for my password, it then began to load but after about 5 seconds went back to the grey screen. I tried logging in over ten times and after failing turned off the mac, now it's doing the loading thing...
Oh and I don't know if this is relevant but I had a mountain lion update that needed to be done?

There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards.

Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in 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.

Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.

My Imac won't go past the grey screen and apple logo! How do I fix the start up in my Imac?

I really need help with this one!
My Imac is stuck on the grey screen with the apple Logo, and it wont go past that.
It does listen to certain keyboard commands to start it up (ive tried fixing it by reading other's posts.) But it will only listen to some commands,
It doesn't start on Shift (safe mode) but it does start on command+shift+(other button) which is safemode viewed so you can see whats going on.
As the letters on the screen type on, it says it's loading something but stays stuck there.
I've heard about a way where you can use terminal from another computer and boot it that way, or using firewire cables.
Please help! and take in mind I'm not really tech-savy with computers, so guides would be helpful!
If there is any way to save the files in the computer that would be great. If it can't be done, it's fine, I just want it working again .
Thanks,
Gian Varela

Starts with white screen and apple logo

After a software update (or during an update) my apple ipod touch does not start up any more.
It starts with the apple logo and after a while the screen turns white or blue and thats it.
Sometimes (after a reset) it starts looping apple logo , white screen, apple logo and so on.
Is not recognized in itunes.

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

Black screen and apple logo! Help please!

This morning phone had blank screen and apple logo only had to do a soft reset

His morning my iPhone 4S had a blank screen with the apple logo and was beeping. could not turn it off or on. Pressed the on/off and other button on lower front and did a reset. Now it cannot connect to my PC. PC cannot find the driver for my iPhone.

Hello there linda,
It sounds like you are not able to turn on your phone after your phone was behaving unexpectedly. I recommend resetting the phone in the same manner you had tried before, but rather than pressing them and letting them go, hold them down as outlined in the following article:
Turn your iOS device off and on (restart) and reset
To reset, press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo.
If the issue persists, I would next recommend putting the device into recovery mode, and then restoring the device with iTunes on your computer:
If you can't update or restore your iOS device
If you are not able to do so and continue to get an error about the driver, you should uninstall and then reinstall iTunes on your PC with either of these articles depending on your version of Windows:
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
Removing and Reinstalling iTunes and other software components for Windows XP
Thank you for using Apple Support Communities.
Take care,
Sterling
