W540 - USB Charging iPad Issue

I have recently purchased a W540 and a Thinkpad Ultra Dock 135W. Is there a reason why none of the USB ports on either the laptop or dock can charge an iPad 2? I have tried them all and only get the message "Not Charging" on the iPad. I believe it is a power output issue but have no idea why and would have expected at least one USB port to be able to charge? I have the dock connected to permanent 240V power as well?? Help!!!

The USB standard only allows a certain amount of power. Some manufacturers choose to ignore this upper limit and allow higher currents.
There is however a workaround to it with an unofficial tool from Gigabyte:

This was reported to work a while back, but I've never tried it myself. It may or may not still work on Haswell machines.

Curve 8330 usb/charging port issues.

My 8330 just started to have problems with its usb/charge port. I plugged it in last night before bed like I always do, but when I woke up it hadn't charged a bit and wasn't even recognizing that it had been plugged in. I tried my USB data cable as well, and that didn't register either unless I wiggled the cord around and held it still once it did register. I eventually did get the phone to register that I had plugged it in, but I had to wiggle the cord just so and leave the charger half-way plugged in once I found the sweet spot.
It is a few years old and pre-owned, but this problem literally just cropped up. I haven't dropped it recently, and I only plug it in once a day. It has no problem holding a charge, but getting it to register the cord is a battle. Do I need to just replace it or is there a way to fix this? There are no other problems, just the port acting up. Thanks!

You can try contacting Sprint for repair options for your device.

Core MIDI from iPad Mini to Mac via lightning USB charging cable

I want to use some of my Core MIDI compatible iPad Apps to control Logic Pro and other DAWs on my MacBook Pro via USB (Core MIDI over WiFi has unmanageable latency issues).
I read on various forums that it is possible to use Core MIDI via USB using the Apple Camera Connection Kit or Lightning to Mini USB adapter, but doesn't this simply work with the included Lightning to USB charging cable?

Image Capture is a built-in program and should be in your Applications folder, Aperture I bought from the Mac App Store.
For Simple Transfer it's an iPad app, so you would download it on your iPad from the app store.

Charging iPad One vs iPad 3rd gen via USB...

just got an iPad 3rd gen. As I've read here, apparently, the PC's USB port doesn't supply enough power to make the 3rd gen battery charging icon say "charging". Instead, it reads "not charging". However, it initially DOES say 'charging', before changing to 'not charging' a couple of minutes later.
Question: my iPad 1st gen ALWAYS charges via PC USB port. Why? Both AC chargers are 10 watts I believe, so why would the 1st gen charge while the third gen doesn't? Does the 3rd gen require more charging watts than the 1st gen unit does?

Using the 10W charger, an iPad 1 will charge in about 3-4 hours, however, the iPad 3 requires about double the time. How long does it take to charge your iPad 1 using the PC's USB port?
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) 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 (2.5W, 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%.

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.

Charging ipad mini issue. Urgent help needed.

Please help me. Past 2 days, I notice my ipad took longer time to fully charge. Normally, it just take around 3-3.5 hours, but now it take 8 hours to complete. What is the problem, was it my ipad, or my charger adapter issue.

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) 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).

Powered USB charging issue

I purchased a Dynex powered USB hub. It's a four port hub and works fine for my M-Audio interface, my iPod Touch 5th gen, iPod Classic... basically anything I plug into it. However, when I plug in my iPad2 it connects to iTunes fine and transferring files is okay, but a message pops up beside the battery icon saying "iPad not charging".
If I unplug the powered USB hub from the wall all the other devices continue to work, but now the iPad is completely unrecognized.
I've tried resetting the iPad and unplugging all the other devices.
It's a drag having this hub in an easy to reach location and still having to reach over to my MacBook in the farthest corner of my desk to plug in my iPad.
Any thoughts/suggestions? Is this common? Should I try another hub at the risk of waisting more money?
Thanks for any feedback.
MacBook 2008 latest Lion, iPad2 (late model) latest IOS 6

The power output from the hub is not the required 10W to charge the iPad (it is charging, but very slowly).
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) 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).

My USB charger is not supporting while i am connecting from PC to iPad for charging (showing as " Not Charging"), Kindly advice me

Hi Folks,
I have tried most of what have been said here ( thank you for the great Job) but unforunatally it didn't solve the issue.
However, now the "Not Charging" message in the right corner disappeared and my iPad is charging normally from my laptop.
The reason behind that is using the USB3.0 port in my Dell inspiron N5110. Earlier, I was using the USB 2.0 ports and that is why it was showing that message but as sooon as I pluged it in the eSATA USB 3.0 port , the message disapeared and the iPad started charging normally.
So don't waste ur time here and there try to plug it to USB 3.0 port and it will works, Insha ALLAH.
Cheers

IPad Not Charging w/ 10 watt non-Apple USB charger

Yes, I've read that the iPad requires a 10 watt charger. I have the original iPad 10W USB charger, and also a high quality 10W USB charger that came with my HP TouchPad. When using the TouchPad charger - which is rated for 5V @ 2A (10W) the iPad says "Not Charging."
Why is that? The TouchPad charger works perfectly with every other USB-powered device I own: hard drives, cameras, phones, TouchPad, etc. The cable works fine with the Apple OEM iPad charger; but stops working when connected to the non-Apple-OEM 10 watt charger. Does the OEM charger send a signal that tells the iPad to charge? Dell power adapters do this (annoyingly). Does Apple do it too? I haven't seen any disclosure of such signals from Apple.
Why does the iPad fail to charge when presented with the proper voltage and current specs? Does the iPad require only Apple-branded chargers?

Bsanders, I've had the EXACT same experience you describe using as you note a very high quality HP Touchpad 10W, 5V USB charger, whether I use the Apple or a 3rd party cable. Despite what Nathan says, I have also had the same experience ("Not Charging" message) using other 3rd party, same voltage if lower wattage, USB chargers that Nathan suggests should work. Only my Apple charger will work and give a prompt charge and there is no specification reason the 10W HP USB charger shouldn't. I am not cutting a cost corner here, rather, I prefer the HP charger design as superior (smaller, same power, smaller interchangeable/twist-on international supply prongs, packs better, black color). I strongly suspect there IS some type of proprietary signal or cabling involved to push users to Apple chargers only. I would ask Nathan to dig a bit deeper for an explanation or workaround. Thanks

Usb charging issue

my incredible charges fine plugged into a wall charger, but when I plug it into my computer to usb charge it cycles through charging/not charging, and it also seems to be an issue with my car charger, I thought the charger was bad but the issue seems to be happening now with my computer also..
any clues?
tia

solved
I went into the verizon store and they told my my phone was no good and I need to replace it, I had a real hard time believing that to be the case and with nothing to lose I played around with the power cables.
I took a pair of needle nose pliers and lightly squeezed the end of the mini usb cable and the problem is solved.
Very disapointed with the verizon store trying to just sell me a new phone, and not even trying to have me try a new car/usb charger.

IPad USB Charger

Does anyone know if the iPad USB charger is the same as the iPhone charger?
I looked up the specs - "what's in the box" and the iPad is a 10 W charger, and the iPhone says its just a charger.
They are the same size, but are they OK to use interchangably?
Thanks

The iPad's charger is twice as powerful as the iPhone's : 10W to 5W. It's safe to use the iPad's charger with the iPhone (http://support.apple.com/kb/HT4327), and charging the iPad with its own charger will be quicker than trying to charge it with the iPhone's charger.

HT1665 Recently read on a deal site forum page that you can only use Apple lightning cables to charge iPads running iOS 7 or higher. Is that the case or will any 8-pin to USB cable work? Thx in advance for any helpful replies.

Recently read on a deal site forum page that you can only use Apple lightning cables to charge iPad Air or iPad Mini Retina running iOS 7 or higher. Is that the case or will any 8-pin to USB cable work? Thx in advance for any helpful replies.

Due to a lot of bad press that Apple was getting due to burnt chargers, shocked users (the electrical kind...), etc., due to the lousy third party El Cheapo brand generics, as of iOS 7 the cable must be Apple-certified before the iGadget deigns to use it for charging purposes. Unfortunately (for Apple) the old traditional USB to 30-pin cable is just that, a straight piece of wire, and can't be validated by the iGadget. But lo & behold, the new gear uses the new Lightning cable, which contains an embedded chip that CAN be validated and lousy imitations disabled from use.

Charging iPhone using iPad USB charger

Is it possible to charge my iPhone with my iPad USB charger or vice versa - or will this invalidate the warranty?
Thanks

You can and it won't invalidate your warranty. It's compatible with all iPhones... http://store.apple.com/us/product/MC359LL/A?mco=MTY3ODQ5OTY
