iPad won't charge

Used iPad for 10 days and suddenly it won't charge thru computer or even AC adaptor. Can't recognized iTunes. Apple system profile doesn't show it is connected.

Try every single method such as reset content and setting, boot into recovery mode, reinstall iTunes... Still nothing happened...

Anyone could help?

Macbook 2008, Mac OS X (10.6.3), iPad

Could be a defective Dock Connector to USB Cable. Try another one if you can.

Could be a defective Dock Connector port.

Make an appointment at your nearest Apple Retail Store and have it looked at. http://www.apple.com/retail/geniusbar/

Just bought an iPAD a few days ago. Drained the battery completely then used the AC adapter via the keyboard/docking station. The iPAD failed to charge. Went up to about 7& then drained again on it's own. Tried charging via USB on current MacPro - this also exhibited the same behavior. Then used Craig's advice and removed all other USB connections, plugged in the iPAD and it now appears to be charging correctly. Strange that an AC adaptor block should fail... I'll return that to Apple.

My iPad stopped charging after my update to IOS 4.2. I have tried a cold boot. I bought a new charger Apple pranded and for the iPad. It just won't charge.
It also won't connect to iTunes on my dell laptop. I have tried rebooting my PC. I get a "device not recognized message. It's 7 mos old, had been pampered in the case and that in a case. This is the first problem I've had and I suspect it was the update that caused it.

Hi -

I have the same problem. Collecting the information from various posts in various threads, you have several options:

1. Try a cold reboot. Press and hold both the power button and the home button at the same time, until you see the Apple logo. This is a cold reboot which will clear most software problems.

Note that this didn't work for me. Still the same problem - the iPad will not charge, and iTunes won't recognize it on either Mac or PC. It wouldn't charge even from a power adapter. If you are still stuck, then you have another option:

2. Try pressing the power button, and as soon as you see the slider, plug in the power. It may fix the problem. This was reported in this thread to work for one or more folks. Note that it didn't work for me.

3. As a stopgap, to keep your iPad usable, you might also try an 'offline charge.' Run the battery power right down to zero. The easiest way to do this is by viewing a long video until the iPad runs out of power. Once it turns off, start it up again, and repeat until it will not start up - and shows a battery icon instead. At that point, plug in the power, and leave it for at least overnight, and preferably around 24 hours.

This worked for me, although it never got to 100% charge. But I could still use the iPad. Each cycle, I could charge it up, and then run it down to zero again. This is highly inconvenient, but at least it works.

3. You can also try completly nuking the iPad altogether, by doing a factory reset. WARNING: If you do this, it will wipe the contents of your iPad. If the problem is that it is not connecting to iTunes due to a physical problem, then you will not be able to restore it - because you cannot connect to iTunes. I did this, at the suggestion of Apple phone support, and it rendered the iPad completely useless.

Nevertheless, if you want to ignore the above warning, you can try going to the Settings -> General menu, and do a full reset. Maybe it will solve the problem. It didn't for me.

4. If you are still stuck, then you can take the device to an Apple Authorized Service center. there However, be advised: the service centers may only have the option of replacing the iPad or not replacing it. What happened to me is that they shined a flashlight into the headphones plug hole, looking at a litmus paper that is placed there. It was pink, indicating that some moisture was present, and they refused to replace it. This is called "LCI", which is apparently Liquid Corrosion Indicator. In reality this is just a "moisture has been present" indicator. Then they refused to help me further. They did not offer any escalation or other options, only mentioning that it would be "very expensive" to fix it. I verified later that "very expensive" means more than the price of a new iPad. Note that I live in Singapore, and my iPad is taken frequently between cool dry air conditioned environments into warm humid environments (that is, anywhere other than in my air conditioned rooms.) I know for a fact it has NEVER been subject to any kind of liquid exposure, except atmosphere. That's the likely reason the LCI was positive. But note below...

5. If your iPad is less than 90 days old, then you should in fact take it to an authorized "repair" center and get it replaced, as it will be under warrantee. This is the easiest thing to do in that case. I believe they will replace it regardless if it is within this period of use.

But there one another option, that worked for me.

Here is what I think was the cause of the problem on my iPad: From what I can determine, there appears to be an issue where moisture (likely due to condensation in humid environments) cause problems in the internal workings of the device. This seems to cause the iPad to be unable to charge or connect to iTunes as a common failure mode. I speculate that it happened to me because I live in Singapore, and because I use air conditioning a lot - but only in certain rooms, as is the practice in Singapore - thus the iPad is taken between cool air conditioned (and dry) environments out of the room into warm humid environments frequently. This could have cause condensation to appear inside the iPad (if it was not sealed) and eventually damage the device. It could especially damage connections internal to the iPad. This will of course also cause the litmus paper in the headphones jack to turn pink, in which case the service center may refuse to help you.

Now I am going to tell you what worked to fix the problem temporarily for me. I do not recommend this unless you are out of all other options and Apple support has told you there is nothing that they can do to help. In my case, my iPad was rendered inoperable, so I had nothing to lose.

6. (If you are out of options) you can try this: hold the iPad from the top (so that the apple connector and home button is facing away from you), and glass facing up. Then bang it on a table, hard enough to give it a good jolt, but obviously not hard enough to break the glass. Lightly at first. Then try plugging it in and see if it connects/charges.

The idea here is that if there is corrosion going on inside the iPad due to moisture, then a good thump can sometimes cause the corroded connections to make contact again. You are trying to jar the connector so that it makes contact properly, so the connector end is the one that you want to bang on the table. It's kind of like smacking your TV lightly with your hand to get it to work.

I cannot guarantee this will solve your problem, and obviously how your treat your iPad is your own business -- but this is what worked for me. It's only a temporary fix, because it does not resolve what is causing the corrosion in the first place, so it will likely die eventually. But this might extend it's life if you have been told by Apple that your only option is to buy a new one, as was the case for me. It probably voids your warrantee, but that doesn't matter if Apple is refusing to help you already.

The other (preventative) tip here is if you live in a humid area, and use air conditioning a lot, you might consider keeping your iPad in the cool and dry environment and not moving it. Or make sure that you don't take it quickly between environments -- let it warm up slowly by turning off the air conditioning and letting the room warm up slowly.

I consider this issue actually to be a design flaw; the iPad, like the iPhone, is designed to be a mobile device. It should actually be airtight to guard against this issue. The fact that Apple will flatly refuse to help you if this happens does not speak well for their support. I personally don't plan to buy another iPad until I see they have addressed this.

Hopefully this is helpful to someone! 🙂

orusku, that makes a lot of sense. but i just had an idea:

you're absolutely right that moist air will condense on a cold ipad, but not a warm one. so all you need to do is make sure that moist air doesn't touch a cold ipad.

all you'd need to do, i think, is get a ziploc bag and put the ipad in it before you leave the cool room. the ipad would warm up in the bag, but the air inside the bag wouldn't be moist. and once it's warm, you can take it out of the bag and it won't cause condensation.

if you want to be extra sure, just put a few little moisture-absorbing packets from bags of chips, etc., in the ziploc bag with the ipad. you could even leave it playing a video in the cool room to keep it warm, or even have it sit in a warm location, like on top of a warmer desktop computer, or even a warming pad.

i'm going to try some of the above techniques - and if it doesn't work, i've got the extended warranty . . . (phew!).

let me know if that makes sense to you.

followup on the charge problem: SOLVED!!

the problem was that the ipad didn't charge fully. i tried different chargers (both OEM and aftermarket) and different cables. it didn't seem to take a charge. the ipad is about 4 months old, used daily in my medical practice to access an EHR and do dictations (and to play world of goo at night). even when plugged into the wall charger during use, the battery percentage kept falling.

orukxu's post (2 or 3 above this) mentions several techniques. i had tried all of them EXCEPT the second one he mentions: turn the ipad completely off (power off by moving the slider after holding the power button on the side until the "slide to power off" appears) and make sure the power cord is out. after that, hit the power button again, and when the slider appears, then plug the power in again.

after doing that (and i did it a few times) it worked! one thing i did that may or may not have had an effect is to charge the ipad into a car charger (plugged into a small jump-start unit's cigarette lighter outlet) after doing the above. i don't know.

still, it's working, and i'm happy again. now i have to go catapult some birds at some pigs . . .
