7th gen Nano only works when plugged in, turns off when unplugged... battery is fully charged.

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,
Pedro.

Ipod nano 4g works good as locked. turns off when unlocked

works good as locked. turns off when unlocked

If you have the Hold switch ON and it's connected to power, the iPod is ON... What happens when you disconnect it like that? Does it stay on for any length of time? Does it immediately turn OFF?
If it immediately (or within a few seconds) turns OFF, I'm not sure what's going on with the Hold switch, but your battery is probably worn out and not holding a charge.
If it stays ON, you are saying it will turn OFF if you move the Hold switch to the OFF position?

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)

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!!

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:
Apple - Concierge
Genius Bar - Apple Retail Store:
http://www.apple.com/retail/geniusbar/
List of Apple Stores, cities, countries:
http://www.apple.com/retail/storelist/
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.

•A reset of NVRAM may help with some issues:

•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!

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:

My 7th gen nano was working fine, now no sound

And yes, I tried two different sets of ear buds and they were both pushed in all the way. It's worked fine for months, now this morning everything appears normal, but there is no sound output. Any ideas? Thanks!

Hey live_music_fan,
I know you have a 7th generation and the article this information is from is for the 6th gen, but the steps should still apply. If you haven't already, I would run through the following:
Check the volume setting.
Try adjusting the volume by pressing the volume buttons.
Try another song or audio file.
Reset iPod by holding down the Sleep/Wake button and Volume Down buttons until you see the Apple logo appear.
My issue is still not resolved. What do I do next?For information on servicing your iPod, go to the iPod Service FAQ.

My 7th Gen nano only synch some of the songs selected from iTunes.

I've restored it and then synched. Different songs synched. I've also re-set it and nothing works. All the Apple software for the Nano and Mac are up-to-date. Does anyone have any insights? Thanks.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Unsync all music and resync
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.

New Problem - It will start when open, but turns off when closed

I started a new thread so that I wouldn't confuse anyone.
I was trying to solve a problem with my G4 not starting after installing an additional DVD drive, but the problem is different now.
The G4 will start and run correctly with it opened up, but as soon as I shut the door, it shuts down.
Any ideas?????
Brian

Hi
I'd check whether any cables are being pinched or crimped as the case is closed. With the case open, you can also apply some light finger pressure to each cable, bending it in the same direction as when the case is closed, to narrow down the problem. It may be a connector is loose, or a cable is damaged internally. I'd pay particular attention to the cable that connects the front panel board (containing the On button etc) to the logic board. This is normally a narrow black ribbon cable and crosses the main case hinge near the front.

HT1414 My iPhone 4s which was working perfectly previously suddenly won't switch on (battery was fully charged!)

iPhone 4s won't switch on. Was fine - was not turned off - just went dead and won't turn on. Any ideas what to do next ?

My 6th gen nano never works unless connected to my computer

my 6th gen nano never works unless connected to my computer. I already restored factory settings twice, it's still not working. It automatically turns off when I unplug it from pc.

If a complete restore of the Nano failed to resolve the issue, the issue is hardware related. In your case it sounds like the battery is shot and in need of a replacement as it can no longer hold or rebuild any sort of charge. You can choose to have Apple swap out the battery for a flat fee or you can send it to a third party service to have them replace the battery for a little less.
If the Nano is less than a year old, it should still be covered under Apple's 1 year warranty against manufacturing defects. In that case, bring to your local Apple Store/Genius Bar and show them what is going on and they should swap it out for you at no cost.

Yoga 13 Turns Off When Plugged In And Won't Charge

I've had my Lenovo Yoga 13 for about a year. When I plug in the laptop to charge it, it turns off and will not charge while it is off. The only way for me to turn it back on is to unplug the charger.
So I guess this is two issues in one: my computer turns off when it's plugged in and it will not charge. Do you guys think it could be caused by a bad charger or do you think it has to do with the computer? Has anyone had this happen to them?
Thanks!

What happens is as soon as I plug in the charger the computer turns off. The battery does not charge while the charger is plugged in and I cannot turn my computer back on until I unplug the charger.
When I first noticed this behavior the battery was about 80% charged and I was able to turn the computer on and use it for multiple hours, so I don't think the battery stopped working. It wasn't until I plugged my computer in again when it was charged under 10% that I realized what had happened wasn't a one time thing; my computer turned off again. I waited about an hour before I unplugged the charger and turned my computer on again. The battery hadn't been charged at all that whole time.

Screen not turning off when closing the lid

I have Windows 7 64-bit installed on my MacBook Air 13.3" as the only OS.
Everything is working great with the bootcamp drivers except that when I close the lid the screen does not turn off. I don't want to turn off the notebook but only want the screen to turn off when the lid is down. I have looked a lot for a solution and am not able to find anything which can solve this problem.
There is nothing in the power options that can be done. Bootcamp is supposed to recognize this by itself, but unfortunately it doesn't.
Does anyone know a work around for this?
Thank you

That is correct. I have noticed the same thing. Windows 7 gives better battery life on MacBook Air then Mac OSX.
I went to talk to a Genius about this, pretty useless, told me to wait for an update. It has been half a year but no update yet. This is the only problem with the Bootcamp drivers I have experienced. I have managed to live with it, but is still pretty annoying. I always once in a while think about finding a way to fix it, but there is nothing that can fix this problem. Unless someone at Apple sees and listens to what is going on in the online fourms and fix the problem.

I get the message Ipod detected but could not identify when i plugged in my new 7th gen Nano. Tried troubleshooting steps with no luck. Tried plugging in my old iPod and i get the same message.

Doublechecking. Have you also tried a complete uninstall of both iTunes and all the other related software components and then a reinstall? If not, try the instructions from the following document:
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8

Pressing "shuffle" on my 7th gen Nano will only randomly pick the first song, then repeats it over and over. How do I get "shuffle to work properly?

My Nike HRM is not working with my 7th gen Nano

I got the 7th Gen Nano a few weeks ago and so far I like it very much. I had a Polar HRM and discovered that my existing HRM transmitter would not
work with the Nano. I got the HRM transmitter that says it works with Nike+ and it's not working. Any suggestions?

When I plug it in iTunes recognizes my iPod, syncs it, but then the iPod library is grey.
If the iPod's Music list is greyed out, that usually means the iPod uses automatic syncing. You cannot change anything directly on the iPod, because you are not manually managing content. You let iTunes manage the content, based on the settings on the iPod's Music settings screen.
Select the iPod in iTunes. In iTunes 12, click the "device button" on the horizontal bar (its icon looks like the device). The iPod's "management" screen comes up, showing the iPod's Summary settings view. Is the box for Manually manage music checked or not checked? If it's not checked, you are using automatic syncing. In the iPod's sidebar, under Settings, click Music to show the iPod's Music settings screen and set up (or update) automatic syncing for songs.

Nano only works via mains charger then freezes when unplugged....

Could use someones wise advice please!
My nano is just over 1yr old, worked fine until recently. I have tried the 5 r's, software is upto date, battery is fully charged, only works via mains charger but when i disconnect it, it freezes with a line through the screen. Connect it to charger, it is fine again.
Via pc usb, the apple logo comes on then it goes black then logo then black screen etc seems it almost boots up but just quite doesnt.
I have found if you hold ccentre button & left scroll button you access an engineers menu, been through all this and it seems fine. Any help would be cool

If the iPod functions normally while plugged into an external power source of some sort (either USB port on your PC or Mac OR while plugged into a wall adapter), but doesn't when running on battery power, it's likely that the iPod's battery is shot.
You can have Apple or a third party repair center replace the battery for a flat fee. Otherwise, it's time to start saving for a new iPod or replacement.
