What machines should be replaced?
Our office recommends you replace the following machines:
Desktops: OptiPlex 9020, 7010, 790, 780, 760, 755, 745, and lower models
Laptops: Latitude E6540, E6530, E6520, E6510, E6500, D630, and lower models
Note: Sometimes, a lower-numbered model will be a newer model, so it’s important that you find out a computer’s warranty status. To determine a Dell computer's status, go to Dell’s support page, type in your computer’s Service Tag (or let the Dell site detect it), verify you are not a robot (if asked), and then review the results.
