Re: Any way to prevent "The AC power adapter type cannot be determined" message on XPS M1710? (AC adapter is properly plugged in)
I had about the same problem except it said "AC Adapter type cannot be determined and the battery will not charge. This was the same adapter it came with and never had any problems with this before. I unplugged and took out the battery twice like Dell recommended. I updated the BIOS. In the BIOS it said the adapter type could not be determined. None of that changed anything. Then about two hours later I unplugged it and plugged it back and it worked. I have no idea why it decided to start working again.
