14.0" touchscreen business ultrabook

The Dell Latitude 5406 is a 14.0" touchscreen ultrabook running Windows 11 Pro on an 8th Gen Intel Core i7 quad-core processor. It ships with 8 GB of DDR4 2133 memory in a dual-channel 4 GB x 2 layout and a 512 GB M.2 2242 SSD. The integrated Intel UHD Graphics drives the 1920 x 1080 FHD panel. This thin-and-light design targets mobile professionals who need pen and finger input in a compact chassis.

65-watt adapter and thin profile

The system draws power from an included 65-watt AC adapter. Its thin-and-light construction weighs between 3 and 3.9 lbs, leaving limited internal airflow compared with larger workstations. Under typical office workloads the quad-core CPU and integrated graphics run within the thermal envelope of the slim chassis. Fan noise remains low during light productivity tasks but will rise during sustained multi-core loads.

Two soldered SO-DIMM slots at capacity

Both memory slots are populated with 4 GB modules, so 8 GB is the shipping total and no slot is free for expansion. The platform supports up to 32 GB of DDR4, but upgrading requires removing the existing sticks. Buyers who need more than 8 GB of RAM out of the box should plan for a full memory replacement rather than a simple add-on.

Questions about this item

How do I upgrade the memory on this Latitude 5406 and what step is often missed?

Both DDR4 slots are filled with 4 GB modules at 2133 MHz. To reach the 32 GB maximum you must remove the existing pair and install two new modules; there is no free slot to simply add more.

Which component will likely need replacement first during long-term ownership?

The 65-watt AC adapter is the only external power source listed; adapters typically wear out before the internal 512 GB M.2 2242 SSD or the soldered-down CPU.

What thermal limit appears first when the quad-core i7-8650U runs sustained workloads?

The integrated Intel UHD Graphics shares the same cooling as the CPU, so GPU-heavy tasks hit the thermal ceiling quickly and throttle both processor and graphics clocks together.
