URGENT - Random Restart Reboot only when Plugged in

I am marking this urgent because I have a term paper due in a couple of days, and this is happening at the worst possible time.
My MacBook, as of last night, has begun shutting down and rebooting automatically. Once it reboots, it finishes loading everything up, and then promptly restarts again. It so far does NOT do this when unplugged from the AC cord. So, as far as I know, when running on battery only, this does not happen
I already have the firmware update installed.
Please help!

Adding to my first post, it also seems to do it when running only on battery WHILE backing up to an external HD with super duper.

Iphone 4 keeps rebooting... but only when plugged in

My iphone keeps rebooting itself... but only when I have it plugged in to the wall. When its not plugged in, it seems to work fine.
We have two iphones in our house... and I have tried the other wall charger... same result.
I went through the recovery mode restore... and its still doing it.
Any suggestions?

If no change after restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup, when your iPhone is connected to your Mac, is it connected direct to a USB port on your computer - not connected to a USB hub?
Since the buzzing/beeps continue when your iPhone is connected to the AC adaptor, do you have another USB dock connector cable to try to rule out a problem with your iPhone's USB cable?

Droid 2 Global: phone staying on only when plugged in.

I've had my phone for about 8 months and I've had no problems until this morning. When I turned my phone on at frist it seemed normal. After it sitting for a second, it cut off. I tried turning it back on and the Motorola screen just kept popping on and off and when plugging it into a charger it would go to the bootloader and say "battery low can not program". I read other threads saying to plug it into the charger and leave it plugged in but my phone was fully charged, from a wall charger, in the first place. Now it only stays on when it is plugged in. WHAT'S GOING ON?

krg2941,
Good afternoon! I'm sorry to learn the phone is being difficult. That's a big bummer! I would recommend you check the charging port on the phone for rust or corrosion, as that could be causing these concerns. Also, popping the battery out for 10-20 seconds while the phone is on, is another good tip. You may benefit from a new battery or a new device if you are unable to resolve with a reboot. Please send me (AdamE_VZW) a direct message for further assistance if necessary.
Thank you,

My com auto reboots only when im playing 'Dota'

Hi!
My com keeps restarting by itself only when i'm playing Dota. My com specs are as follows:
CPU: Intel E7200 Duo Core 2.53GHz
Mother Board: MSI MS-7345
Memory Brand: Cosair DDR2 1GB
Video Card: WinFast PX8600 GTS TDH 256MB DDR3 128 Bit
Hard Drive: Seagate 250 GB
OS: Microsoft Windows XP Professional SP2
Power Supply Unit: 350W (output), 12V2 18amps (input)
It is interesting to note that whenever my com restarts, it will show the 'blue' screen before rebooting. After rebooting, my mouse will seem to be 'disconnect' and i would have to replug it in again or it will not work. I am using a Razer Diamondback Mouse (Not 3D mouse). My keyboard is a normal BenQ keboard with nothing fanciful.
My comp temp flutuates from the following temps when I'm playing 'Dota':
Motherboard: 42 to 46deg
VGA: 50 to 54deg
I suspect that it is my PSU, any comments anyone?

How to turn on backlit keyboard only when plugged in to the power

Hi there,
is there any way I can have the backlit keyboard turn on only when the laptop is plugged into the wall outlet and not when it is running on battery?
thanks!

Not that I know of. Your only option is to use the F5/F6 keys to turn on/off when needed/not needed.

My iphone 4 is stuck on the apple log then goes to plug into itunes only when plugged in.

my iphone is only accesable when pluged in and when plugged in it goes on and of from the apple logo and then if i hold the sleep wake and home botton it will go to restore mode/connect to itunes.

Oops I mean I don't have a computer*

Ipod in endless reboot loop when plugged in?

I acquired an ipod touch 2nd generation from a friend, and they don't know what's wrong with it, and neither do I. I've tried all the tricks by pressing the home and power buttons, plugging it into itunes, trying to restore it, etc.
When I try to plug it in, it'll power up to the apple logo, and then reset, so all I ever see is the apple logo and it won't go any further. I can get it into restore mode, but when I hit restore in itunes, I get an error.
Also, it doesn't actually power on unless it's plugged in, so this led me to believe it was a battery issue maybe?
I have no idea if it was ever jailbroken, or how it was used. It has some cracks in the screen, but does power on when plugged in, so it's not COMPLETELY broken.
Any ideas?

Error 1604
This error is often related to USB timing. Try changing USB ports, using a different dock connector to USB cable, and other available USB troubleshooting steps (troubleshooting USB connections. If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.
If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:
Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode,put it into Recovery Mode.
Restore and wait for the error.
When prompted, click OK.
Close and reopen iTunes while the device remains connected.
The device should now be recognized in Recovery Mode again.
Try to restore again.
If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection.

MacBook Pro w/ Retina Display 15-inch 2012 making strange cricket-like noise (only when plugged in)

Hi guys, I have a year old retina MBP. Recently, it just started making this high-pitched whirring cricket-like sounds. Although pretty quiet, the sound is pretty annoying. This sound has a few strange characteristics that make it hard for me to pin it down to any component:
- the sound only occurs when laptop is PLUGGED IN, when my laptop is not plugged (on battery), there is no sound
- reducing the screen brightness, reduces the sound but does not make it go away (even with no backlight, the sound is still there)
- the sound occurs mostly when performing going into MISSION CONTROL or swiping between desktops. It also sometimes happens randomly, but that is less common. It follows the inputs of trackpad and keyboard, though mostly mission control swipes and desktop changes. It doesn't coincide with intensive CPU, GPU, RAM or SSD tasks (ie running a CPU/GPU heavy app, or compressing a file does not increase the quantity of sound)
- I am not very sure where the sound originates from, might be from the top left of the keyboard (q key), but it is also louder near the speakers.
ALSO:
- It is not from the fans, as they occur when fans are running slow or fast and this sound is unaffected by any changes in fan speed
- reducing backlight has no effect
- turning automatic graphic off or on has no effect
- resetting NVRAM, etc. has no effect
Most likely theory:
- some kind of faulty capacitor maybe?
- but then which part of the laptop to replace....
- I don't have Applecare, but I do have a third-party warranty; they've agreed to replace the faulty part...
- I've read the forums and have seen people with similar problems (though never this exactly; replacing fans and logic board does not seem to help)

guiparent,
whether it’s worth the price or not is an entirely subjective opinion. My own choice was to buy a used non-Retina 13-inch Mid 2010 MacBook Pro, and replace its hard drive with a SSD; but since I don’t use graphic-intensive apps such as the Adobe Creative Suite, my own choice would most likely not be best for you. Given your graphic design background, if you find the non-Retina displays sufficient for your needs, I’d recommend that you consider a used 15-inch Mid 2012 MacBook Pro. That model has memory sockets, so you can replace/upgrade the RAM if needed; its internal disk can be replaced by/upgraded with any 2.5-inch 9.5-mm-high SATA hard disk or SSD; and it has a built-in SuperDrive.

Shutting off....only when plugged in.

I know there are a lot of posts out there about the ibook shutting off, but mine has some peculiarities I didn't see in others, so before I take my computer apart as was the conclusion here http://discussions.apple.com/thread.jspa?threadID=1082138&tstart=0, I'll give this a shot.
My ibook randomly (when in use mostly but sometimes not) shuts down, though I don't think all the way. The screen goes black, and it is quieter, but there is still some sound, indicating it is on somehow. I remove the battery, unplug, wait a bit, put it back in, sometimes this works fine. Sometimes I have to repeat the process.
I should note a few things:
This ONLY happens when the power cord is plugged in.
The power cord is not made by apple, it is a replacement cord.
This started happening after buying and using a different replacement cord than the one I am currently using. This particular cord actually died on me. It still had some power, but not enough to power my ibook.
Does anyone have any recommendations? Even just what to ask if I take it to a mac place?

Do you happen to have iStatPro? It is a widget available from the Apple Web Site. I am wondering if the whirring noise you hear is your fan? Intensive applications tend to raise the temperature of everything and cause the fan to come on.
You might also put activity monitor in your dock and check the CPU usage during some of these big applications. I'm wondering if you are running it almost at its limits and it might be getting overheated and shutting down for that reason. I am not a gamer, but possibly some other member of the forum is and has experienced this phenomonon. I'm not sure of this, but I think the iBook is designed to shut itself off before incurring damage from overheating. I don't know what HD, processor, or RAM you have, but it might be helpful to post that. And also, how much free space there is on your HD. I probably can't help any more, but it might give another gamer enough information to confirm or refute my guess.
Good luck!

Ipod Touch is working only when plugged to a charger.

I haven't been using my Ipod for over a month. It wasn't used by anybody at all to be specific. Yesterday, I got it back and tried to use it. First it was charging for about 40 minutes, but after this it turned on and worked correctly. I left it charging a few hours more, and when I came back, unplugged it, Ipod wasn't working. I plugged it back, magic, it's working again. So I left it charging over the night, but when I checked it today's morning it gave the same results. Maybe You've got some solutions i could use.
2 Important things:
- It works only with a wallcharger, not with a computer cable.
- I wouldn't like to go to a service because my warranty has expired.

You can try resetting it by holding down the home and sleep keys, past the power down, and until you see the silver apple logo. Let it reboot and then let it charge and see if it holds the charge. If it doesn't then your battery may have died. Afraid that isn't user servicable. You can either take it into an authorized repair place or you can take it to a third party repair shop. Using hte non-authorized place will void your warranty, but if your warranty is done like you said, then it may be cheaper and doesn't matter as much.

Random songs automatically playing when plugged in

Whenever i plug my iphone 5 into my ihome dock or car deck it automatially plays a random song in my library even if i had a song or playlist selected. it will exit it out of whatever i was last listening to. also exits what im listening to when unplugged and re plugged in even if i have shuffle off. Been doing this since i update to IOS7. how do i fix this so it will function properly like it did in ios6

but when I unplug, it only shows 3/4 charged up. When I unplug device, it says 'no battery power remains, please connect ipod to power'.
What? So does it show only 3/4 a charge or does it say no battery power remains?
Either way, it sounds like the battery lost it's ability to retain a charge and it totally shot. You'll need to have the iPod battery replaced in order to gain full functionality of the iPod again. Apple can swap it out for you for a flat fee or you can send it into a third party repair center to have the job done a little less.

Has anyone else had the issue of the the screen randomly flashing black only when using Messages app in landscape?

I have been having an issue with the screen flashing black for several seconds then turning back on. This olny occurs in the Messages app and only in landscape mode. I have never noticed the issue in any other app. The issue is 100% repeatable. Has anyone else had this issue or know of any solutions to what seems to be a bug?
-iPhone 5s running iOS 7.1
KCM

I think this is an issue with the phone's proximity sensor (the one that turns the screen off when you hold it up to your ear). It's a bug that seems to occur when you switch to another app (any app) while still on a phone call. You'll notice in Messages that the screen goes dark when you move your thumb over the earpiece/iSight camera, but not when you move your other thumb.
Simplest solution is to force-quit the Messages app (double-click the home button, and swipe up on the app). The problem should resolve itself when you restart Messages.

Powerbook Operates Only When Plugged In? Battery Seems Dead? READ THIS

I posted this several days ago for Powebook G4 17'. I thought this could help others...
I just saved several hundred $$$$, thanks to another Apple customer who had posted this tip somewhere in Discussions.
My Powerbook suddenly crashed a couple of days ago, due do a faulty Apple Firewire cable. It would not immediately start, and my first thought was that the logic board was fried. Remembering that I should try to set the PRAM and then possibly the PMU, but forgetting what keys to press, I frantically searched for my users manual. 15 minutes later, I found it, I followed the instructions, and my PB successfully booted. My troubles were far from over. I soon realized that the battery now appeared to be completely drained. The PB would only work with the power cable plugged in, despite the battery showing 98% charged. When the cable was removed or wiggled, the computer would promptly shut down. I reset the PRAM and PMU several times, reset permissions, cleaned caches, checked preference files and other regular maintenance procedures.... No improvement. I then ran the hardware test that's on my original PB software disk. Everything, including the logic board, tested fine. I then used TechTool Deluxe, and everything tested OK as well. I reset the PRAM, PMU again, but the Powerbook still would not operate on battery power only.
Yesterday, somewhere on this discussion board, I read this tip:
With the battery still in, start up the computer, log in if necessary, and get to your desktop. Close the lid so the PB goes to sleep and walk away. Don't touch it for at least 3 hours. Open the lid so it wakes from sleep, then unplug the power cord.
IT WORKED! I was completely shocked.
I've been using my Powerbook on battery power for more than an hour. The menu bar shows the current battery charge as 40%. I thought it may be a good idea to recalibrate the battery, so I'm letting the battery drain completely.
I'd like to thank the kind person who posted this suggestion. You saved me a few hundred bucks, and I appreciate it.
PowerBook G4 17 Mac OS X (10.4.8)

Power Issues Galore!! I purchased (against my better judgement) an overpriced Powerbook G4 in March 2005 (when Apple claimed that the G4 processor was "faster than Intel", which is the exactly the opposite of what they claim now that they use Intel) and alas, recently purchased an iMac for same college student who is quite the Apple fan, and basically required to have Apple products due to college policies and curriculum. The Powerbook power supply has been a constant problem, which we temporarily resolved by purchasing 3rd party products. Now the plug on the unit itself is loose! Could have bought 4 PC laptops for purchase price of the Powerbook! Time will tell about the iMac.
My opinion, based on personal experiences, is that Apple fans are delusional about the quality of Apple products. Given this, since I have spent a lot of money purchasing Apples, I guess I am a little confused myself!!

PowerBook G4 17 Mac OS X (10.4.7) 1 G RAM, a HUGE sigh of relief

Fan buzzing only when plugged in?

Hello all,
I've noticed a low buzzing coming from the rear fan sometimes when the iBook get's really hot. Thing is, it never happens when on the battery, just when it's plugged in. It's not too loud at all, but it is noticable compared to the otherwise silent like hiss of the fans normally. It almost sounds like the tiny blades are softly brushing against something. When the laptop cools down a bit, the noise goes away, and I just hear the silent like fan again.
Again, this never happens when the iBook is running off the battery alone. My energy saver settings for power adapter and battery are both set to Automatic CPU.
I took it to the local Apple store to have it checked out. They tested the fans, while plugged in, and there was no problem. I even sat there for an hour and a half running intensive games - games that produce the sound at home - and nothing. I think it's just too cold in the Apple store
Any ideas? Why would this only be happening when the laptop is plugged in?

There's definately no "unusual" sound coming from my hard drive. When I turn the iBook around and put my ear to the back vent, it's pretty apparent that that's where the noise is coming from.
Also, when I brought the iBook in to the Apple store to have it checked out, the service tech ran a utility that cranked the rear fan to the max. The fan, when activated manually, sounded fine. It just made a normal "fan noise". Of course the iBook is cool during this process, and refused to get hot enough in the store (it's an ice box in there).
When the iBook gets really hot, and the fan kicks on, there's a distint "buzzing" that happens from the rear fan. It must be temperature related. The heat must expand a part near the fan or something, because it sounds as if the blades of the fan are rubbing against something.
Apple can't reproduce it in the store, so they won't do any work on it. I just hope it's nothing that will harm the computer over time.
