Superer90W 65W AC Charger for Dell Latitude E5440 14" LED Notebook Laptop Power Supply Adapter Cord

How do I get the dell laptop to recognise thi charger when laptop boots up?

can I use this charger on my dell inspiron15 laptop?

Will this work for the Dell latitude 5590? It lists the 5590 in 2 of your descriptions, but the 5590 is not listed in the 2 other descriptions.

Will this work on 7410 Latitude model?
