My ipod touch would not be charged on my laptop.
It's not recognized either.
Problem is the cable is fine and ipod touch itself is fine because they both work fine on my desktop.
It's not USB port problem because if I plug the thumb drive, it works fine.
What it's doing is, when the device is connected and locked, the batter charging sign keep flashing (showing in one sec, then next sec not showing)
Occasionally, the window pops up saying it found the ipod, but it goes away in 2 sec and starts keep doing it again.
