Hey guys- I've ran into a problem with my laptop over the past couple of days. I have a Dell Inspiron 1420 running Windows Vista, and the battery and charger have been working fine up until recently. Several days ago I plugged my wall charger into my laptop, and instead of seeing the battery meter in the tray showing it's charging, I get an error message: "The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 65W AC adapter or higher for best system operation". Some of what I've read around the Internets suggest that the battery is toast, but it's been holding a charge just fine lately, and I haven't received any kind of message suggesting the battery's nearing the end of its use life. Before I go and spend money on a new battery and/or wall charger, has anyone run into this problem before?
