Quad-Core Performance and Upgradeable RAM

The refurbished Dell Latitude 3400 is powered by the Intel Core i5-8265U — an 8th generation quad-core processor running up to 3.9GHz. Choose 8GB of RAM for straightforward everyday use, or step up to 16GB if you regularly run more demanding multitasking workloads, paired with a 128GB or 256GB SSD depending on how much local storage you need. Unlike many laptops in this class, the two SO-DIMM slots are accessible, meaning RAM can be upgraded by a technician later if your needs change, supporting up to 32GB DDR4 in total. This is a genuine practical advantage over increasingly common soldered-memory designs, since it lets buyers extend the useful life of the laptop as their software needs grow, rather than being locked into whatever configuration they originally purchased.

A Genuinely Full Port Set

The port set is comprehensive: two USB-A ports, USB-C with DisplayPort and Power Delivery, a USB 2.0 port, HDMI 1.4, wired Gigabit Ethernet, an SD card reader and a VGA port for connecting to older projectors — a practical feature for office and classroom environments that haven’t yet upgraded their display hardware. The 56Wh battery comfortably covers a full working day of typical office use, and the combination of wired Ethernet, VGA and modern USB-C in one machine means buyers rarely need to carry a bag of adapters between older and newer meeting rooms.

MIL-STD-810G Durability

Despite its accessible price point, the Latitude 3400 is certified to MIL-STD-810G military durability standards covering drops, humidity, vibration and extreme temperatures. The chassis is built to withstand the daily wear and tear of shared office equipment better than many consumer-grade laptops in a similar price bracket.

Who Is This For?

The refurbished Dell Latitude 3400 is an excellent choice for office workers and small businesses who need a reliable, practical 14-inch laptop with a full port set including wired Ethernet and VGA, and anyone upgrading from an older machine who wants solid everyday performance at an accessible refurbished price without sacrificing legacy connectivity.

Not ideal for: gaming or 3D design work. For office work, study and everyday use, the Latitude 3400 is a strong fit.

Typical Use Cases

This configuration suits office administration and small business use where a stable wired network connection and legacy VGA support matter, classrooms and meeting rooms with older projectors that lack HDMI or USB-C inputs, and buyers who want genuinely upgradeable RAM rather than soldered memory. The accessible SO-DIMM slots also suit IT departments that prefer to standardise on hardware they can upgrade in-house rather than replace outright.

Refurbished vs New at This Price Point

Dell has moved on to newer Latitude 3000-series generations, and this exact configuration is no longer sold new — there is no genuine current equivalent to compare directly. Why pay £££ for new? A current entry-level business laptop with a comparable full port set costs substantially more than this certified refurbished unit. Buying refurbished from Primo Technology gets you a tested and warrantied laptop at one of the more accessible prices in our Dell business range, with the added benefit of genuinely upgradeable RAM that many current entry-level laptops no longer offer.
