DELL Latitude 5400 i7-8665U 1.9GHz 16GB 2000GB SSD 14.0 laptop

Business laptop with 14.0" screen

The DELL Latitude 5400 is a business laptop built around a 14.0" display and an Intel Core i7-8665U processor running at 1.9GHz. It ships with 16GB of memory and a 2000GB solid-state drive for fast boot and application loading. Windows 10 Pro comes pre-installed and a charger is included. This configuration suits mobile professionals who need a reliable daily driver for office applications and web-based workflows.

Thermals and power in normal use

The ultra-low-voltage 1.9GHz processor keeps heat output modest during typical productivity tasks such as document editing, email and video calls. Fan activity remains subdued under these loads, so acoustic output stays low in quiet environments. Battery life benefits from the efficient chip and solid-state storage, allowing extended unplugged sessions. The supplied AC adapter recharges the internal battery when mains power is available.

Behaviour under sustained load

When the CPU is driven continuously at higher frequencies, the compact chassis causes temperatures to rise and the cooling fan spins up noticeably. Thermal throttling may reduce clock speeds during prolonged heavy workloads such as large compiles or data analysis. The 16GB memory ceiling limits the size of datasets that can stay resident without paging to the 2000GB drive. Buyers who need sustained multi-core performance or more memory headroom should consider a larger workstation-class machine.
