DELL Latitude 7400 5400 14" i7-8650U 32GB 1TB

Business ultrabook for mobile professionals

The Dell Latitude 7400 is a 14.0" thin-and-light laptop built for business users who need a compact Windows 10 Pro machine. It ships with a quad-core Intel Core i7 8th Gen processor, 32GB of DDR4 2133 memory in a 16 GB x 2 configuration and a 1TB M.2 2242 SSD. The 1920 x 1080 non-touch display and integrated Intel UHD Graphics suit office applications and video calls.

Thermals, noise and power draw

A 65-watt AC adapter powers the system during normal workloads such as document editing, web browsing and conferencing. The ultrabook chassis dissipates heat quietly under typical office use, keeping fan noise low while the processor maintains steady performance. Power consumption scales with CPU load but remains within the adapter’s rated output for everyday tasks.

Build integration and expandability

Both memory slots are populated, so the 32GB maximum is already reached and no further RAM upgrades are possible. Storage uses a single M.2 2242 drive bay; adding a second drive is not supported. Connectivity includes two USB 3.1 ports, one Thunderbolt 3 port with DisplayPort functionality, one HDMI output and an RJ-45 Ethernet jack on the 5400 variant. The integrated webcam and dual-band wireless with Bluetooth cover conferencing needs without extra peripherals.
