My Palm IIIC will either not charge or cannot detect the battery charge properly. It charges overnight, then I take it out of the charger and watch the battery charge indicator. It goes from full to half to one third to zero back up to three fourths back to zero in about the time it took me to write that. Just today it shut itself off as it does when the battery is dead. I turned it back on, it shut itself off. I turned it back on again, but this time it stayed on for half an hour. It seems as confused as I am.
