DELL Latitude 5400 14" FHD Touchscreen i5-8350U 16GB 128GB SSD

14-inch FHD touchscreen ultrabook

The Dell Latitude 5400 is a 14.0-inch ultrabook with a 1920 x 1080 touchscreen display. It runs on an 8th Gen Intel Core i5-8350U quad-core processor paired with 16GB of DDR4 2133 memory in a dual-channel configuration. A 128GB M.2 2242 SSD provides the primary storage, while Intel UHD Graphics handles visual output. Windows 10 Pro comes pre-installed for immediate deployment.

Thermals, noise and 65-watt power draw

The system ships with a 65-watt AC adapter that defines its typical power envelope during normal office workloads. The ultrabook chassis manages heat from the quad-core processor and integrated graphics without discrete GPU overhead. Fan activity scales with sustained CPU load, staying subdued during document editing or video conferencing. No liquid cooling or specialised thermal hardware is present in this form factor.

Upgrade path from smaller SSD or less RAM

This configuration replaces a unit limited to 8GB of soldered memory or a drive below 128GB. The M.2 2242 slot supports up to 1TB, allowing a straightforward capacity increase when local storage becomes a bottleneck. Memory slots are fully populated at 16GB, so further expansion requires module replacement up to the 32GB maximum. Buyers who need Thunderbolt 3 connectivity or a lighter sub-3-pound chassis should consider other models.
