Does anyone know if you can use the same power adapters from a Latitude 610 with a newer Latitude 620? 

 

The part numbers are different on Dell's website but looking at the two of them, they seem to be the same - voltage, wattage, connector, etc.  I ask because I just got a 620 and have a couple extra power adapters for my old 610 and it could be handy. 

 

Thanks!
