Dell Latitude 5400 Repair

The Latitude series was originally launched in 1994, and is a long line of portable laptops consisting of hundreds of models. The Latitude 5400 however, was released in 2019 featuring an 8th generation intel processor, 14 inch display, Wi-Fi and Bluetooth support, integrated graphics drivers, and an HD resolution webcam. The Latitude 5400 is a laptop developed by Dell focused on it's business capabilities in software such as Microsoft Office and it's respective programs.

As of December 4th 2025, Dell has not instated any emergency health or safety recalls on the Latitude 5400 series of business laptops.

It is possible to quickly determine your laptop is a Dell Latitude 5400 by checking a few important locations. First, check the bottom cover. The Dell team usually would have provided either a label or etching that highlights the model number as “Latitude 5400.” Next, open the Dell BIOS/UEFI menus by pressing F2 when your computer starts up. The exact model name will be shown on the main system information page. In Windows there is also a way to double-check- go to Settings > System > About or in the Start menu you can type “msinfo32” to create a system summary that includes the model. Some notable features distinguishing the Latitude 5400, aside from it being a 14-inch laptop, is that it has a USB-C port for DisplayPort, and that some configurations have a smart-card reader which will assist in verifying the model number.
