Forced restart loop/not recognizing restarts
Hello, when I power on my MacBook, I get the message You Need to Restart your computer, Hold the power button for several seconds or press the restart button. Naturally I hold down the power button image displayed the in the backround and sure enough after a couple of seconds my screen goes black and my computer powers off. When powering back on thought, my hard drive (I think) makes the noise as thought it is waking up from being asleep, and I get the tradional mac power on sound effects from my speakers, apple display than immediatly back to the you need to restart message.
Help?
What you have described is called a Kernel Panic. If the issue happens when you are in your OS and it happens consistently when you're in there, it's possible your Hard Drive needs to be replaced. However, if you are getting anything like that on startup, the Main Logic Board could be failing.
On the other hand, now you're getting booted into Verbose Mode with a strange error... I wouldn't try to do any more troubleshooting if I couldn't boot to my install CD. The only other thing you can try is zap the PRAM or try Safe Boot. If those fail, it's gotta be sent for repair.

All of this randomly started happening. I've remapped the drive, reinstalled iTunes, formatted the iPod, and countless restores.
I've started it in diagnostic mode and everything checks. The headphones work in my laptop as well as sounded the tones for the headphones check in diagnostic mode.
I've spent about 3-4 hours total trying to do various things and I'm stumped. Please help. I cannot go to an Apple store because I am currently deployed. I've had this iPod for less than 2 months and it would be great to get things working agian.
Thank you.Nothing huh? No one's had this problem or this isn't fixable... oh well... if anybody comes up with anything I'll check in occasionally...

Update 1.02- Now continuous restart loop- New Classic 80Gb
Went to synch 2-week old 80Gb classic. Prompted for update, waited until after synch. Then clicked update. Came back later and iPod stuck in a continuous restart loop. Reset/Restart does not work, computer doesn't see it untils it boots...hosed.
Any ideas...?This was finally resolved, so I thought best to post the results.
*Call #1 to Apple:*
Poor English speaking tech, very hard to even get the address right, and very little product knowledge resulted in returning it to Apple. Within 2 days prepaid box arrived and I shipped back. Within a week, the reply that nothing wrong, or may have been corrected via diagnostic testing- software update, etc.. Worth noting no charge.
Received it back, turned on and woohoo...the menu. Plugged into and opened iTunes. First thing I noticed..FORMATTED WINDOWS (FAT32), even though it left me, and I told Apple I was a Mac user. OK- who cares, as long as it works. Did a full synch, the iPod restarted and right back into the loop of restarts again.
Call #2 to Apple:
This time an English speaking, knowledgeable tech who, for the first time, had me put the iPod into disk mode (center/menu until logo, then center/play until disk mode) and for the first time the iPod was seen by iTunes.
He walked me through the restore, menu came up and began synching. All looked good so I let him go at 40Gb of stuff takes some time. BUT as synch completed, iPod restarted and was stuck in the loop again.
Call #3 to Apple:
This call started bad, tech not really understanding history of things so far, new case ID, and had me doing things already done. However, eventually a product specialist and the tech support call we all dream of. Methodical and full knowledge of the iPod. First thing, clear out old iPod software update files to force new download. Then log in to another user (we all have one right?), and going through the restore in the fresh iTunes. Brought some tunes in from CD, synched and finally a working iPod. OK, now back to the other user.
1. Trashed iTunes library file in my user, and moved the iTune Music Library.xml to the desktop.
2. iPod to disk mode, opened iTunes, cancelled erase and synch, did restore, and manually put some tunes on it. All good.
3. Went through adding tunes and checking, all good.
4. Final was Import the previous iTunes Music Library on the desktop, and synch only a few items. All good.
5. Synch some more, couple hundred, and all good.
6. Final synch all music and let it go. All good.
7. And finally, add photos, TV shows, movies, contacts, calendars, etc. and all flawless.....
So...appears the end result was either a corrupt iTunes Library file or iTunes Music Library.xml file. Note that other iPods (2 shuffles, and a 3G 20Gb) continued to synch without issues, only the new classic suffered from the corrupt files..
As a note: As far as Apple Support was concerned I didn't like the fact that each time new Case ID's assigned, or that I had to constantly explain the "sequence of events" leading up to the current call. In addition, the first call was worthless and had I talked to tech from call number three, it would have been fixed then without even sending in.
Anyway, hope this all helps someone...problem solved. -
HELP!!!
Here are the specs of my machine:
2011 13.3" MacBook Pro
4 GB Ram/320 GB HD
For the past several months my MacBook Pro refuses to shut down or restart without holding down the power button. Whenever I choose to restart or shut down the computer, it will hang on a grey screen. I have even tried letting it hang for an hour, and it still won't shut down. I notice that once in a while it will retart or shut down correctly if I had not used opened iTunes since turning it on. However, even manually closing iTunes before shutting down or restarting does not solve the problem. It seems as though it only shuts down if iTunes was not used since restarting the computer. Is this a registry error? Do I need to reinstall iTunes? I noticed this problem began happening after I uninstalled Kaspersky Virus Scanner, could that be the problem as well? Also, I cannot guarantee that the problem is only associated with iTunes. I just noticed that one of the few times it shut down or restarted correctly, iTunes coincidentally had not been used. Also, this problem started happening while I was still using Lion and has continued despite upgrading to Mountain Lion.
Also, whenever I update my iPod through iTunes, it won't eject properly, and a transparent icon of the iPod displays on the screen even after I have removed it from the USB port. Furthermore, the iPod will only be recognized by iTunes and will only be updated the first time I plug it in. After removing it and plugging it back in, it won't recognize or update the device unless I shut down and restart the computer. I have the latest addition of iTunes. I also have two iPods, one 80 GB Classic, and one 8 GB Nano, and I have the same problem with both.
I have AppleCare. Should I take my macbook to the genius bar?
Applications I normally use are Word, Safari, FireFox, iTunes, FinalDraft, Photo Booth, Notes, Mail, App Store, etc. No real heavy lifting.
Any feedback would be very much appreciated. :-)
Thank you everyone!!I have this question too.

Ok, so here's the not so sad story. I bought an iPod Touch 2g 16g through Ebay - so forget warranties. Luckily I did not pay much. The description said it was stuck on the apple logo, so I figured it would be an easy put into recovery mode and restore problem.
Not so much.
If you plug the iPod in and charge up the battery the LCD will come to life after a while with the apple logo, then it displays the spinning wheel with the apple logo over it. That will last anywhere from 10 - 15 minutes, then the iPod will go blank for a few secs and then start up the cycle all over again.
As stated, this iPod will NOT enter either DFU or recovery mode and believe me I've tried it several times several different ways with different timings, connected via USB to a Mac, connected to a different Mac running Windows, and connected to just the charger. Nothing. Occasionally the screen might go blank while holding the power and home buttons but nothing else happens and then it starts it's usual cycle again.
Again, iPod NOT recognized by iTunes on either Mac or Windows side. Since I got off Ebay and seller didn't know much about it, I have no idea if someone tried to jailbreak this or not.
I will not put much money into this machine. So I guess my question is: does this behavior mean that the motherboard is clearly fried? Are there any software programs that might diagnose what the problem is? Could it be as simple as a fried battery?
And most importantly, is this iPod simply toast or is there anything anyone can suggest????
Really any suggestions would be greatly greatly appreciated. Seems a shame to just trash an iPod touch that might need a simple fix...
If it helps matters, I can tinker with iPods somewhat and have torn down and replaced several iPod touch 1g and 2g glass and digitizers with no problems. I'm somewhat software savvy but the whole jailbreak thing is new territory... and I can't really figure out the command in Windows or Mac terminals to list all connected devices so I have no idea if the computer even knows the iPod is there, even if iTunes doesn't. Guess that's it... ummm, please help???Nothing huh? No one's had this problem or this isn't fixable... oh well... if anybody comes up with anything I'll check in occasionally...

My iPod and iPhone are not recognized in Windows 7 iTunes. I've reinstalled iTunes and restarted windows. Now iPod briefly displays, then device manager mass storage shows a yellow exclamation point. iPhone doesn't display in iTunes at all. Please advise
Try Andrei Cerbu's post here, JF Fourie's post here, or see TS1538: iOS: Device not recognized in iTunes for Windows, in particular section 5, forcing a driver update. See also TS1363: iPod: Appears in Windows but not in iTunes.

Cannot switch after restart because bluetooth not recognized
I am having a problem switching from OSX to windows because my bluetooth keyboard is not recognized during restart. So i am not able to hit the Alt(option) button while restarting to get the option of switching. Is there a way to fix/go around this?
thank you.Not really - that would be the easiest option; I also have an older keybord nearby (also because Bluetooth is not as 100% troublefree as a wired connection). So, yes buy a third party keyboard or borrow one from a neighbor...

Thank you for visiting the HP Support Forums and Welcome. I have read about your HP ENVY 15 Notebook and having issues with the startup stuck on HP Logo. You could reset the BIOS with this document selecting the reloading the BIOS default settings.
Please note remove any and all USB devices. Disconnect all non-essential devices, as these could cause some issues.
Here is a link on computer does not start, which has a section for the HP Logo screen. Most times this is an issue with something you have just installed.
Hope this helps you.
Thanks.

Can nayone help. thank you in advance.
So even in Disk Mode the iPod is not recognized by your PC or iTunes software? Are you plugging the iPod into a high powered USB 2.0 port? Have you tried a different USB sync cable to verify that your current cable isn't faulty or damaged?
I assume you are using the latest version of iTunes correct?

Stuck in Restart Loop after Software Update
I recently ran the update to 10.5.3 a few days ago, and thankfully, it's been working great... until today, when I installed two seemingly innocuous updates via Software Update: one for the latest version of Quicktime and another for Apple Brother Print Drivers 1.1. After restarting, everything fell apart. Several of my start-up apps unexpectedly quit after login, and other apps either failed to launch when I tried opening them, or they simply got stuck in an endless loop of bouncing in the dock. I couldn't even force-quit them because they weren't responding at all. Thinking this strange behavior to be symptoms of some permissions issue, I popped in the Leopard installation CD and ran a permissions repair. It fixed several cryptic problems, one for something to do with Java and another for the cups folder, which I assume has some relation to the printer driver update. I then tried selecting my start-up disk and restarting, but the problem only got worse. Now my iMac is stuck in a restart loop. I tried booting in safe mode, but that hasn't worked. If worse comes to worst, I'll have to revert to a Time Machine backup, or else run an Archive & Install, but I'm trying to avoid that. Any suggestions? I'm also curious to know if these two updates had any relevance to these problems, and if so, what the cause may be. I'm thinking the printer driver is to blame, but then again that's only a stab in the dark. Any help would be appreciated. Thanks!
Thanks for the suggestions. I tried a Safe Boot again but unfortunately that didn't work, so I had to go ahead and do an Archive & Install. Now everything is up and running; however, I'm going to stay away from that print driver until I figure out exactly what went wrong. I did a little research and saw it listed on MacUpdate.com, where it was posted along with an interesting note: apparently, the update can only be applied if there is already a Brother print driver installed (in this case there was), and in addition to that, the printer must either be connected (and I assume on for the computer to know it's connected in the first place) or have an active print queue for the update to even be listed in Software Update. Strangely enough, neither of these conditions held true when I saw it in Software Update... so I think that might have been the cause, but I can't be sure. I was wondering if anyone else has installed this update successfully, and if so, what they did?
Thanks again for the suggestions. -
Stuck in an Endless Restart Loop
My Mac Pro 8-core running OS 10.5.4 is stuck in an endless restart loop. The problem started when I tried to allow read & write access on my Macintosh HD to another user. Even though I only applied the permission change to my internal hard drive, all my externals suddenly became locked and I could not access them. When going to set permissions on the externals, it was listed as "custom" and I could not alter them. I went to the terminal to try to allow access to the external drives, but the terminal failed to load. That's when I tried restarting my computer and it's now rebooting constantly without ever loading.
What I've tried so far:
-I can't load the OSX install CD because the computer is unresponsive to the open tray command by holding down the mouse click.
-The computer is unresponsive when I try to start in safe mode.
-The computer is unresponsive when I hold down command option O F to force the tray open with firmware.
-I reset the PRAM by pressing command option P R, this is the only keyboard command that has worked so far, but still nothing.
-I unplugged the computer for 10 minutes and plugged it back in. Still nothing.
Any help on what to do next would be appreciated.I'm having a similar problem.. my early 2008 3Ghz macro when cold starts up the fans rev up and click its off. this repeats for up to five minutes, then i get a chime and then it shuts off. this is repeated for a will as if it is warming up. after about ten minutes it gets as far as finishing booting up and still shuts off. only after about 15 minutes this operating system is stable and does not shut off.
when the computer is fully warmed up it shuts off and restarts fine..
it has recently had a new logic board. can it be the power supply..
please any one got any ideas??? -
4th Gen Classic in Restart Loop
Greetings,
I have a 4th generation classic, 60gb iPod stuck in a continuous restart loop.
I've been able to put it into disk mode and it is recognizable by iTunes where I did a restore to it after which it went back into a restart loop again. I then put it back into disk mode and erased said iPod with Disk Repair and did a zero out on the drive. Restored again via iTunes and, after resetting, has refused to come out of its restart loop.
I can load music onto it and everything but use it as an actual iPod.
Is this the logic board needing a replace or is there something else I can do?A. I've done a restore 3 times and it still does the restart loop as well as after a full wipe via Disc Repair. Aka, then it must not be a software problem
B. I can ONLY get it recognized on my computer in disk mode. Aka I can not use it as an ipod to play music as it refuses to load up out side of disk mode. It falls right into the restart loop after a soft reset.
Fortunately, I've been able to get all of my music files backed up from the disk mode. -
3rd gen iPod caught in restarting loop
As of yesterday morning my 3rd gen scroll wheel iPod has been restarting itself over and over. None of the suggestions on Apple's website have helped (I've tried both the standard restarting technique, toggling the hold switch and holding down play/menu, and the select button/menu technique). It's not under warranty anymore and I don't particularly relish the idea of paying $249 to replace it, so I thought I'd see if anyone here had any suggestions on troubleshooting this issue - I don't care if I lose data, I just want it to play music again.
3rd gen iPod scroll wheel 15GB Mac OS X (10.4.3)Same iPod same restarting loop problem. I put it in forced disk mode but I can't see the disk when connected to the computer with finder even with iTunes. So the latest iPod Updater doesn't see my iPod.
So I can't Restore it.

Pre 2 Lunacy ...Luna restart loop...
Been running Pre2 with 2.1 & preware mods... Luna started self-restarting randomly... More and more frequently over subsequent days. Occasionally would get stuck in restart loop where the animated pulsing-hp logo would suddenly freeze and then restart again (assume luna restart aborted and restarted itself again before presenting user screen.) When caught in this luna restart loop (lunacy), I was forced to do a "triple-toggle restart" after which the lunacy would seem to be cured. Did this several time over several days.
THEN... This morning went to check mail when lunacy started. TWO subsequent triple-toggle device restarts failed to get past lunacy. Third (?) came up announcing I needed to restart, re-login to my Palm account to restore my phone! (all the way back to "English?" prompt)
Now... All apps restored and amazingly including 2.1 new features and my completely rearranged launcher pages (ala Preware mods!) Took me back to 2.0 (apparently) since now suggesting I upgrade to 2.1 !!! BUT.... Been here before and the 2.1 upgrade collided with my Preware patches, leading me to have to doctor the thing!
A) is my hardware the problem or is this understood behavior?
B) diagnostic tools to use?
C) should I allow upgrade to 2.1 to proceed when it does not seem necessary?
....help appreciated!
Post relates to: HP TouchPad (WiFi)Yes... Went to apps catalog and installed the new Bing maps program. Tried it out and liked it! Installed it as soon as it was announced... Now something has changed. The restore of my Palm profile remove bing maps ...so I reinstalled it. Then luna restarts on its own and remove it!
Seriously thinking someone has been playing with exploiting the open-ness of webos, trying to use recovery and update features of the system to install malware. The bing vrs google dispute just provided a convenient test case masqurading as a "protest".
