Magsafe will not charge...is this correct?
Hello all,
I have a 15" 2008 MBP and just bought a 13" unibody. I just discovered that the power adapter for the 13" will not will not charge the 15" or even illuminate the LED on the Magsafe, whether running or not. Is this to be expected? I had believed the adapter would at least be able to charge the 15" when the machine was not running.
The converse of this (15" supply on 13") does work, although I don't plan to do this regularly.
Thanks for any ideas on this situation!
bliberty: It should work: you should be able to charge the 15" machine with the 60W (not 65W) adapter that came with the 13" model, at least when the bigger machine is not running and no bus-powered peripherals are connected to it. Unfortunately, if everything works properly when the right adapter is used with each machine, there's no malfunction that Apple is likely to help you with.
I would reset the 15" machine's SMC and then try it again.

Any thoughts about my second go around with an I pad that will not charge. This is second go around and I'm wondering if I should repalce or opt out and go different route ???? Can not imagin that Apple could give the type of support I'm recieving and continue?? The first one was under warranty not so lucky this time.
Go to the Apple Store and try a different charger & cable.
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

In rare instances when using the Camera Connection Kit, you may notice that iPad does not charge after using the Camera Connection Kit. Disconnecting and reconnecting the iPad from the charger will resolve this issue.

The icon is telling you that you have to connect it to your computer. If iTunes sees the iPod then you should get messages that tells you what to do.

My ipod touch will not charge or connect via usb
When i plug in my ipod touch, it only recognizes that it is plugged in for a few seconds at a time. Therefore, it will not charge, and this occurs no matter what cable i use with it, whether i plug it into my computer, or into the wall with an adapter. I also cannot use itunes with it because of this. I have already looked through the forums for other people having the same problem, but most of them just got useless answers such as checking the troubleshooting guide. I would prefer a "REAL" answer to this. To be completely honest, all that the troubleshooting guide tells you is how to do an idiot-check on yourself. I have only had the ipod for a few months, two at the most, so a depleted number of recharges in the battery is highly unlikely, especially since the computer also will not recognize it. An error message comes up saying that it does not recognize the device. Thanks for any help!
I have checked for problems with the connections, but from what i can see with the naked eye, nothing appears abnormal. It is very strange, and very sudden. It just stopped in the middle of a charge. The apple store is my next step. I just wanted to see if anyone on here had some extremely eye-opening solution or check. thanks though!
I'm also within warranty, so it's not a huge problem. -
My Iphone 6 Plus I got 2 days ago will NOT charge
OK, so I have been having issues with this phone since I took it out of the box. First it would blue screen everytime I would turn it on. Hard resets and tried everything finally it would at least stay on....and got it activated. Now, I let it charge all night. Well I thought it was charging. I get up and the phone is at 1% and WILL NOT charge above this. I unplug and it immediately shuts down. So is it my phone and should I have it replaced or is it a bug and I'm not the only one? HELP!
Thanks for giving those steps a try for us brett762. If a hard reset has not resolved the issue, there may most certainly be a hard ware defect. In this case we would recommend replacing the device. Being new it would be within warranty in order to have it replaced. We would not be able to see our store locations inventory, but you can certainly contact a store near you to check their stock http://vz.to/1sTbdCW.

My iPhone 4s will not charge in car or truck. It would appear after research that this is a software issue with ios5. Will there ever be a patch to correct this infuriating problem?!!!
Mine charges just fine, as does everyone's iPhone 4S that I know. Apple even sells a number of car chargers that are certified to work:

Perhaps there is a problem with your charger or the outlet you're using in your car/truck. -
My nano will not charge. Which is correct port on my macbook pro for this?

Since updating my phone to the new operating system my phone will not charge most of the time. It shows that it is charging but the battery percentage decreases rather than increases. Is anyone else having this issue?
Are you using a non-Apple Lightning cable? iOS 7 added controls to prevent non-branded Lightning cables from working.
If you're using a genuine Apple cable then perhaps try a Reset of your iPhone. If that does not help, then do a backup and full Restore and reload your backup. -
My Iphone 5 will not Charge! what should I do?
Please stop giving this - wrong - advice.
This "hard" reset is essentially pulling the power from the phone without giving it a chance to clean up and power down gracefully.
Would you recommend to people to pull the power plug from the wall on a running computer to solve an issue?
The proper way to restart is to hold down the Sleep/Wake switch, then Slide to power off. Push the switch again to power back on.
This gives the phone a chance to shutdown properly by flushing the caches and buffers, closing open files, and terminating running processes correctly. Pulling power with a "hard" reset can corrupt the data on the phone and make things worse. It achieves nothing extra than a proper restart.
The only reason to do what you are advising is when the phone is completely frozen and will not respond to the normal shutdown. -
Hello Everyone,
This is my first time using the forum. My macbook battery will not charge. I have tried unplugging and doing an SMC reset but it did not seem to change. I have yet to try another magsafe charger. The charger has a dim green light while plugged into the computer. What should my next steps be, besides trying a new charger as well as being the most cost effective?
Thanks

The battery may need replacing.
Check the battery maximum cycle count > Mac notebooks: Determining battery cycle count
And check the adapter > Apple Portables: Troubleshooting MagSafe adapters -
My Macbook Pro will not charge. I have tried other charges and nothing. Can the MagSafe port go bad? Is that expensive to repair?
The port can fail. Internal boards can fail. Batteries can fail. All with the result that no charging occurs.
You can try Resetting the System Management Controller and you can try Troubleshooting MagSafe adapters.
But usually you will have to take the mac in to a service place for testing. It can get expensive, although occasionally it is not.

Just Upgraded my IPOD 5 to iOS 7.0.2 and it will not charge the battery anymore.
When I plug it in, it now gives the message "This cable or accessory is not certified and may not work reliably with this IPOD".
Anyone else have this issue after they upgraded the iOS system?

You have 14 days from the date of purchase to return your MBP. Personally, I would not waste my time "troubleshooting" if the normal solutions do not work.
Return the MBP for one that works before your 14 days are up and/or call AppleCare ASAP!!!
Good luck!
