DELL Latitude E5440 14" laptop i5-4200U 16GB 256GB SSD

Built for everyday work

The Dell Latitude E5440 is a 14 inch laptop with an Intel Core i5 4th Gen dual-core processor running at 2.60 GHz. It ships with 16 GB of DDR3 memory in a dual-channel configuration and a 2.5 inch 256 GB SSD. Windows 10 Pro 64-bit comes pre-installed. The HD+ display offers a 1600 x 900 resolution on a non-touch panel. Integrated graphics handle standard office and web tasks.

Thermals and power in normal use

The low-voltage processor and integrated graphics keep heat output modest during typical productivity workloads. Fan noise remains low when browsing or editing documents. Power draw stays within the limits of the standard Dell power adapter supplied with the system. The chassis dissipates warmth through the keyboard deck and bottom vents without becoming uncomfortable during extended sessions.

Behaviour under sustained load

Under continuous heavy compute tasks the dual-core CPU will throttle to maintain thermal limits, so peak clock speeds are not held indefinitely. Integrated graphics performance drops further when the processor and GPU share the thermal budget. The 16 GB DDR3 configuration helps avoid paging during long compiles or large spreadsheet calculations. Buyers who need discrete GPU acceleration or higher multi-core throughput should consider other platforms.
