DELL Latitude 7400 5400 14" i5-8350U 16GB 512GB laptop

Ultrabook for business travel

The Dell Latitude 7400 5400 is a 14.0" Windows 11 Pro ultrabook built around an 8th Gen Intel Core i5-8350U quad-core processor. It ships with 16GB of DDR4 2133 memory in a dual-channel 8 GB x 2 configuration and a 512GB M.2 2242 SSD. The 1920 x 1080 non-touch display, integrated Intel UHD Graphics and 65-watt AC adapter complete a compact package suited to mobile professionals.

Thunderbolt 3 port limits dock choice

The 7400 model provides a single Thunderbolt 3 port with DisplayPort functionality alongside two USB 3.1 ports, HDMI and RJ-45 Ethernet. That lone Thunderbolt connection is the only gateway for high-speed docks or external GPUs, so users needing multiple 4K displays or daisy-chained devices must verify hub compatibility carefully. The 5400 variant replaces this port with a third USB 3.1 connection and lacks Thunderbolt entirely.

Soldered memory caps upgrades at 16GB

Both SO-DIMM slots are populated at the factory, leaving zero available slots for expansion. The platform supports a maximum of 32GB, but reaching that figure requires replacing the existing modules rather than adding to them. Buyers who anticipate memory growth beyond 16GB should consider this constraint before purchase.
