ISight Turns Off, Must Unplug Firewire
Hello:
I keep my iSight turned off (i.e., lens cap closed, green light off) when I'm not video chatting. I turn it on before initiating each chat or responding to an invitation.
Lately, iSight has been doing a strange thing when I turn it on. It initially works (i.e., green light on, my image on screen), then it dies (green light off, image frozen). No matter how many times I twist and untwist the ring to turn it on and off, it remains frozen.
The only solution I've found is to unplug, then replug, the Firewire at the back of my Mac Mini. This always brings iSight back to life.
Any clues as to why my iSight behaves this way? I assume that it shouldn't.
FYI...I use SightSpeed as my video chat service (**** "XXX will not respond" problem!), but I don't see why that would be the cause.
Thanks for any comments.
Sal
... SightSpeed ... but I don't see why that would be the cause.I do not know why either. Perhaps it is a Possible hardware or software conflicts with another third party component of your system?
Have you recently performed Mac OS X maintenance? If not, try it now, and see if your problem abates.
Have you checked with the SightSpeed Support site for help? If the problem relates to your third party application, their FAQs or Help / Technical Support services should be able to give you suggestions.
The suggestions in Apple's What to do if your computer won't recognize a FireWire device kBase Article may help you if your problem relates to your Firewire ports or to an internet connection that may be holding onto port settings when you shut your iSight off.
If you think the problem might be with your iSight itself, you can check your iSight using the suggestion in How to test your iSight to ensure it is functional.

'm sure your'e going to tell me I just need a new phone but maybe there is hope for my iphone 4. It will not charge past 66% (it's not the charger), it turns off when unplugged, and it will not even let me turn my wi fi to the on possition. Help!
Hi there 8472kck!
I have some information for you that can help you troubleshoot this issue a little further. That information can be found right here:
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 15 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
and that information comes from this article:

My iPhone 4s was playing music now won't on my sony dream machine how do I fix. "This device is not supported by this I-phone". I have turned off phone unplugged sony and did the pin reset on bottom. Help please I need my tunes
Try plugging it up to your computer and launching iTunes and either resetting it to factory settings or resetting to last sync. Hopefully it just noticing it's plugged up to iTunes will fix it. This happened to my friend once and all she had to do was plug it into her computer and that fixed it.

ISight turns off and wont turn back on
Up until yesterday my iSight was functioning properly. I tried to ichat with it, and I noticed that the green light was not on. The white lens cover was not on, and I had it plugged into the firewire port in the front of the tower. I did notice that is got very hot. I unplugged it and let it cool for the night. Today, I plugged it in and the light goes green for a few seconds and then the iSight makes a noise, similar to when it adjusts for light, and turns off. I also tried the camera on my other mac G4, with the same result.
Software Update doesn't pull up an isight upgrade, so I must be current.
Any thoughts?
MatHi David,
Essentially the same questions.
have you tried it with iChat Open ?
With the App Shut down ?
Reseating the cablesa t both ends ?

Macbook works fine when plugged in, turns off when unplugged.
Hello all,
As stated my 2008 Unibody 13 inch, serial number W8******1AX turns on and works fine when it is connected to power.
When it is unplugged it instantly turns off and turns its fans on full until it depletes the battery (so it is obviously getting power.. just not where I want it)
Since the problem began I have tried two new batteries, neither of which had any different symptoms.
Before this, the computer had an intermittent life, it would turn off when it saw fit, which got progressively worse.
I have followed the guides to resetting the SMC but have had no luck
I have been running it without the battery (to save it charging and discharging for no reason) and sometimes when plugged in without a battery
the magsafe green indicator light goes from dim to bright.
With the battery installed it stays bright orange until it is charged and then switches to bright green.
(I have tried it with another charger, same symptoms)
Here is the Battery Read out;

I'm at my wits end with this thing, I know it is getting on in age, but other then this, it has been flawless in its operation.
If anyone has any suggestions I would be happy to hear them.
Many thanks!!
<Edited By Host>There may be a hardware cause behind the symptoms you cite, so a diagnostic
is recommended to see which parts are weak or failed in the computer. A visit to
an Apple Store with Genius bar may be helpful, as they can perform testing there.
A call ahead or use their web page, to schedule an appointment, is advised.
In the US and Canada, the Genius bar at a retail Apple Store can perform
a diagnostic service, for no fee, even on Apple products without AppleCare.
See links:

List of Apple Stores, cities, countries:

Also authorized Apple service providers who can test, repair and guarantee their
work should be able to handle an out-of-warranty older Mac, within age limits...
Ones too old for the Apple Store could be serviced at a Specialist, instead.

•Did you try resetting the System Management Controller?

•Calibrating is part of maintenance, esp with older portables:
Apple Portables: Calibrating your computer's battery for best performance
•The power adapter can be problematic and cause issues, so there's this:
Apple Portables: Troubleshooting MagSafe adapters
Also another item, other than keeping the magnetic connections clean of
debris, grime, and corrosion, is to check the MagSafe Board or have it
checked as part of a greater diagnostic. This board is behind the port
that supplies the computer and the battery with power from the adapter.
When it partially fails or if/when one of the connecting wires or plug fails
you can find odd issues or partial use. The battery may charge but it
may not be able to power the computer, and other odd effects.
https://www.ifixit.com/Device/MacBook
In older portable Macs, this was generally called a 'DC-in board' and as
such, you could read about it in an iFixit repair guide for the MacBook
model you have. These vary so the matching article is recommended to
see if that is something you may want to try. But I would have diagnostic
testing done and avoid additional damages from attempted DIY efforts.
There have been a few reports of other failure on the logic board that
contributes to a partial failure of the charging system, so about all this
may do is troubleshoot around the failure without finding an exact cause.
However it goes...
Good luck & happy computing! -
Nano turns off after unplugging from computer
My nano works fine, if its plugged into my computer. When I eject and then unplug it turns off and I can't get it to turn back on. Once I managed to unplug and get it to turn on, then turned it off then I tried to turn it on again 5 mins later but nothing. Battery says it's off and I go through making sure everything is off or paused at least before unplugging but same result everytime.
I think this is ridiculous. I got the iPod nano 4th generation (8gb) this summer and my click wheel isn't working. Apple is making a huge mistake by ignoring our emails which could lead to business loss.
But!! I know how to get it working (for a while).
You just leave your ipod alone for about a week or two. And it's completely responsive. But unfortunately if you plug it into the computer, the wheel will become unresponsive again. It costs more to fix than to buy. <-- Crazy
The only thing is that i've lost the reciept ¬¬' But if you go to an official apple store. I've got a great excuse or whatever to why you deserve a new ipod or money back. It is 3 years garentee and it has only been made for 2 years.
Going to the store soon so i'll see if i can give you guys some info. -
Macbook turn off when unplug magsafe but the battery is 98%
Magsafe plugged : side battery led 8 light, computer 100% work but if i unplug magsafe computer turn off.
Magsafe unplugged: side battery led not work an computer not work.
I've reset SMC and PRAM but not work
do you think the battery is damaged?do you think the battery is damaged?
Could be - unusual problem. I don't think that there's much that we can do for your here - best to take your machine to your local Apple Store or an AASP for a diagnosis.

My ibook loses battery power when turned off and unplugged
I have been puzzled by this since November 2006. I calibrated my battery twice as prescribed and still, as soon as i shut down my ibook and unplug it, it's battery charge goes down. Why is this? I'd greatly appreciate help. I'm a former pc user and none of my pc laptops have this problem. I just want to know why my battery loss power when unplugged and turned off. thanks in advance
Well you might want to try what they call "battery reconditioning" which is 7 simple steps listed below:
1: Charge your iPod fully.
2: Use it till you cant trun it on anymore!
3: Then carge your iPod fully again.
4: Then Use it till you cant trun it on anymore!
5: One more time charge your iPod fully.
6: And then again Use it till you cant trun it on anymore!
7: Then one last time charge it fully again.
Reminder: it is best to let the battery die all of the way each time inbetween chages. for example if it has 60% battery life dont charge it use it till it is dead and then charge it up all the way!
*This should inturn maximise your battey life also!* -
my computer battery says it is fully charged. then when i unplug it the screen comes up that asks "shutdown" "restart" "cancel" and regardless of what you push or if you dont push anything, the computer turns off. i have another macbook and i have switched the batteries and this computer still continues to do that with another battery in it. it sounds to me like this may be a problem with a setting, but can anyone tell me where i might could find that setting? thanks!
and the message is "are you sure you want to shut down your computer now?" (restart) (sleep) (cancel) (shut down)
or is it "your computer is running on reserve power" ? -
Iphone turning off once unplugged from charger
my battery is at least 30% but when I take it off the charger for a second it turns off and wont turn on until I plug it back into the charger, and this only happens on occasions (mainly when I am in a hurry). I just don't know why it does it, and its not like my battery is too low to keep the phone on. HELP
Hi
Thanks for the replies.
I have this afternoon taken the phone to a third party repair service store.
They took the battery out and used a fully charged battery, which i saw power another iphone.
This did not fix the issue.
The gent in the repair shop told me that it looks like a logic board fault. He also mentioned that it looks like it had been tampered with!
He also advised that he has seen a huge increase of this sort of thing happening on ebay.
He wished me luck with it and closed the phone up.
So it looks like i am now left with a dead phone and a fight with ebay! :-(
Cheers all. -
Turn off after unplug the power cord
Hi,
I have a MacBook Pro form 6-8 months and everything works great but from 2-3 days ago now everytime when i disconnect the power cord from the computer the system turn off.
I think the battery is good because i can use the computer only with battery (like im doing right now) and if i press the battery indicator button all green lights turn on and i can use the computer for 1-2 hours using battery only but for some reason if i connect the power cable again and disconnect later the computer is turned off.
I install all updates by apple.

7th gen Nano only works when plugged into computer, as soon as I unplug it shuts off (it was ejected from iTunes). Battery is fully charged. Have already done a restore in iTunes and checked for updated software.
Hello there, DizDude.
The following Knowledge Base article offers up some good recommendations for troubleshooting battery issues with the 7th generation iPod Nano:
iPod nano (7th generation): Hardware troubleshooting
http://support.apple.com/kb/TS4433
Particularly this section:
Battery life appears short
Learn how to conserve battery life.
Ensure that the latest software is installed on the iPod.
When charging, use the cable that came with iPod nano (7th generation) and leave the device connected until it is fully charged.
Note: If you are charging using your computer, don't connect iPod nano (7th generation) to your keyboard. Also, the computer must be turned on and not in sleep or standby mode. If iPod nano (7th generation) is connected to a computer that's not turned on or is in sleep or standby mode, the iPod nano (7th generation) battery may drain.
When you are done using the iPod nano, verify that:
The Radio application is off (tap the button)
Music is paused (tap the button in the iPod application or disconnect the earphones)
There is no active Pedometer session (tap the Stop button in the Fitness application)
Dimming the screen is another way to extend battery life on iPod nano. Go to Settings > General > Brightness and restore the brightness to the default, or drag the slider to the left to lower the default screen brightness.
Playing tracks with EQ requires your iPod processor to consume more energy than playing tracks without EQ, because the EQ information is not encoded in the song. To prolong battery life, turn EQ off if you don't use it. Go to Settings > Music > EQ and select Off from the list. Note, however, that if you've added EQ to tracks in iTunes, you'll need to set EQ to Flat to have the effect of Off, because iPod keeps your iTunes settings intact.
Try restoring iPod nano (7th generation) by connecting it to iTunes and clicking Restore.
Test the battery life.
Issue not resolved
If the issue is still not resolved, please read this information on servicing your iPod.
Thanks for reaching out to Apple Support Communities.
Cheers,

MacBook Pro turns off when unplugged from outlet
I have a MacBook Pro Intel Core Duo 2.26GHz
2 days ago when I unplugged it from the wall it shut off. It has been doing this since even though the battery is fully charged.
Once it is off I am able to turn it back on not plugged in and use it for the full length of the battery without problem.
Anyone would know what would cause this? and how to fix it?
ThxI would try the SMC reset.

Airport turns off - must shut down and turn back on
Hi. I am wondering if anybody else is having a similar problem with their late 2008 MacBook aluminum. In the last few weeks I have found that Airport on the MacBook will not turn on. This usually happens when I start the computer. Airport does not start up. I can click the Turn Airport On from the drop down menu as much as I want, and the command is ignored. I must shutdown the MacBook and restart it. That usually fixes the problem.
My router is an Airport Extreme which I purchased in April of 2007.
Anyone else experiencing this problem?One of the Apple software updates has apparently fixed this problem.

IPhone 4 turning off after unplugged from wall or PC/MAC
Hi
Can someone help please?
I sold my iphone 4 recently and it was returned to me.
The guy had it for 6 hours and it suddenly crashed apparently (this is his words)!
He then tried to restore and it failed with unknown error 21.
Im no stranger to resetting and sorting an iphone out but this one has me banging my head against a brick wall.
I have tried to restore and the same error occurs.
I have also tried entering into DFU mode etc and the same results.
Volume up and down and resetting still no change.
I took it to the apple store as a last hope to see what they said and they dvised it had been tampered with so would not test any parts!
Should i try a new battery? Or is this something else? Has anyone seen this before?
Needless to say i am furious as i personally feel that this may have been a drop/water damage or jailbreak gone wrong or, even worse, a logic board swap SCAM.
Any help would be great.
