iPod touch Weird charging problem (4th gen iPod Touch)

[j.dstasio]

I have a 4th gen iPod touch with an odd charging problem. When the battery is completely dead (black screen) I can plug the iPod in with a USB cable to my MacBook air or a wall charger and it will indicate that it's charging. After a few minutes it will power on, but as soon as it boots it stops charging. iTunes does not recognize that it's plugged in.

Any ideas?

Can you try another cable? I'm wondering if the cable has gone bad (broken wire; fried resistor) and, once the iPod is charged, it doesn't "detect" a valid cable. The iPod cable is not just wires; it has some resistors inside to let the device know what kind of cable is attached.

I tried several cables and chargers (both Apple OE and third party). It didn't make a difference. I'll probably make an appointment to have it looked at. it is under warranty.

I just thought it was odd that it seemed to charge normally until it booted and then nothing.

I've had the exact same problem with my iPad 2. I got it replaced at an Apple store, but here's what's wrong:

For an unknown reason, the dock connector is disabled when booted into iOS. Due to this, you cannot charge or sync.

if you desperately need to charge, then:

1. Connect charger and boot into iOS
2. Hold down the sleep/wake button and "slide to power off"

Although there is a black screen and the device appears to be off, it will still charge. It just takes about twice as long.

Try holding the power button and home button down at the same time while it's booted until it appears to switch off, then try to charge it again. That's how I fixed mine when I had exactly the same problem (it would turn on, display the battery charging icon except the icon was red with a dodgy looking symbol on it and it wouldn't let me use the iPod, after I reset it and plugged it back in it switched itself on like normal and began charging as normal too as well as let me use it).
