I have been having this problem with erratic charging. I have been having it all day today. I just now did an experiment. I connected the device to my PC and clicked on the Connect to PC button. I then turned off the screen and the blinking yellow light started pulsing. On the PC I opened a file manager to the device SD card. I thought that if the USB connection was dropped, the file manager would show it. After a few minuets I checked the device and the yellow light had stopped pulsing. However, the file manager was still connected and I could navigate the folders. Can someone explain this to me? This makes me thing the problem may also be software related. I have now turned off the device and am charging it with the power off. So far it seems to be working because the yellow light is still pulsing. PS: Maybe we should start another poll thread since many that originally voted "No problems" may by now be experiencing the problem. That would be me, for example.
