DELL Latitude 5540 laptop i7-1355U 16GB 4TB PCIe SSD 15.6 FHD

Business laptop with large SSD

The Dell Latitude 5540 is a 15.6-inch business laptop built around a 13th Gen Intel Core i7-1355U processor with 10 cores and 12 threads. It ships with 16GB of DDR4 memory and a 4TB PCIe NVMe SSD running Windows 11 Pro. The configuration targets professionals who need ample local storage and modern connectivity in a 3.56lb chassis.

Sustained workload behaviour

The i7-1355U combines two performance cores with eight efficient cores and can reach 5 GHz turbo frequency. Under continuous load the 12MB L3 cache and 15W base power envelope keep thermals manageable inside the slim chassis. Integrated Iris Xe graphics handle typical office visualisation and external 4K output at 60 Hz through HDMI 2.0 or Thunderbolt 4 without a discrete GPU.

Upgrade context and fit

This unit replaces an older business notebook that lacks Thunderbolt 4, WiFi 6E or a multi-terabyte NVMe drive. The jump is worthwhile when local datasets exceed 1TB or when dual 4K docking through a single cable becomes a daily requirement. Buyers who need discrete graphics, a touchscreen or user-replaceable memory should look elsewhere.
