I bought a targus ac adapter, it worked the first time I charged my Dell 5100 Notebook computor, now a message comes up saying it doesn't recognize the ac adaptor, how can I fix this?


AC adaptor may not be correct. Check label on AC adaptor with label on notebook for voltage (e.g. 19.5V or 20V) and current (e.g. ??A or 90W)

Voltage must be same and current must be same or higher on ac adaptor.
