It’s easy to access all the components of the Latitude 5420 if you ever need to repair or upgrade the machine. The back cover is held on with standard Phillips-head screws and internal plastic clips, which are easy to unscrew and unsnap. You can easily replace the laptop’s memory, storage, battery, fan, wireless card, speakers, and display. If you’re more experienced with repairs or if you work in IT, you can repair or replace nearly any component of the machine. For instance, even the power button is its own module that you can swap out if you remove nearly all the internal components, including the battery, motherboard, and inner frame. This level of repairability is unrivaled in comparison against ultrabooks or MacBooks and not seen on most other laptops available. Dell publishes a nice service manual to make repairs easier.
