Sharon,   Try reading Electricity Around the World. On the adapter it will tell you what the voltage range is and you can compare it.     Rick
I have an employee using a Vostro 1015 Config 020, Genuine Windows® 7 Professional, 32bit laptop in Ireland.  A local tech there told her " that with new laptops you don’t need to use a converter because they have a built in one", and I need to find out if that is true. Thanks! Sharon
