Background and Identification
The Dell Latitude E6420 was released in 2011. This laptop typically ships with Windows 7 Pro installed and can come with a Core i3, i5 or i7 processor. Most laptops come with the Core i5 processor and onboard Intel graphics.
This laptop is meant to be an office-to-home business laptop. It has a sleek black color with silver around the edges. This silver edge distinguishes the E6420 from the E6400 and E6410, which are solidly colored. The laptop features a 14" LED backlit display and an optional backlit keyboard. The Latitude E6420 received its fair share of favorable reviews.
The Dell Latitude E6420 was only manufactured in 2011-2012 and has since been replaced by many newer Dell Latitude laptops. Despite this, the Dell Latitude E6420 was well built, still has many useful features, and does not need to go to waste if the laptop works and meets your needs.
