Dell Latitude 5420 — 14" Business Laptop
A certified refurbished 11th Gen business ultraportable, professionally tested and backed by a 12-month warranty. Intel Core i5-1145G7, 16GB of dual-channel DDR4 and a 256GB NVMe SSD in a 14" chassis built for daily commercial use.
Key Benefits
-
11th Gen Intel Core i5-1145G7 — four cores and eight threads with Turbo Boost to 4.4GHz, comfortably ahead of the 8th Gen machines still common in refurbished stock.
-
16GB DDR4-3200 dual-channel — two 8GB modules running in dual channel, enough headroom for a full browser session alongside Teams, Excel and Outlook without swapping to disk.
-
256GB NVMe solid state drive — PCIe NVMe rather than SATA, so boot and file access are near-instant.
-
Thunderbolt 4 and USB-C — single-cable docking for power, display and data, plus HDMI and USB-A for older peripherals.
-
Wi-Fi 6 and Gigabit Ethernet — Intel AX201 wireless plus a real RJ45 port, which most ultraportables have dropped.
-
Windows 11 Pro with TPM 2.0 — domain join, BitLocker and Group Policy ready for managed environments.
Performance In Use
The Latitude 5420 sits in Dell’s mainstream commercial line, which is where most of their engineering effort on serviceability goes. The i5-1145G7 is a Tiger Lake part that holds its turbo clocks longer than the low-power chips found in thinner consumer machines. In practice that means a busy browser session, a large Excel model and a Teams video call run together without the fan cycling constantly.
Sixteen gigabytes of dual-channel DDR4 is the specification that ages best. Dual channel matters more than the raw figure on Iris Xe graphics, which draws on system memory — a single-module 16GB machine gives up meaningful graphics performance against this configuration. Paired with the NVMe SSD, cold boot to desktop is a matter of seconds and applications load without the pause a SATA drive introduces.
The 14" panel on this configuration is a 1366 × 768 HD display. That is a lower resolution than the Full HD panels this chassis is often fitted with, and the price reflects it. For spreadsheet work, line-of-business applications, remote desktop sessions and general office use it is perfectly serviceable; if you spend your day in two documents side by side, choose one of the Full HD configurations in this same family instead.

Frequently Asked Questions
What screen resolution does this configuration have?
This one is the 14" HD panel at 1366 × 768. The Latitude 5420 chassis is also sold with Full HD panels — if you need 1920 × 1080, choose one of the Full HD listings in this family rather than this one.
Does it come with Windows, and is it genuine?
Yes. It ships with Windows 11 Pro 64-bit, professionally reimaged and activated, ready to join a domain or Azure AD.
Can the memory or storage be upgraded later?
Yes. The Latitude 5420 has two SODIMM slots and an M.2 NVMe bay, both accessible under the base cover.
How long will the battery last?
Battery health is graded with the machine — 70% or better for Grade A, 50–70% for Grade B. Batteries are consumable and carry a 30-day battery warranty. Replacements are available if you need all-day runtime.
Will it work with my existing dock?
It supports Thunderbolt 4 and USB-C docking, so any Dell WD or TB-series dock and most third-party USB-C docks will drive power, display and data down one cable.
What does shipping cost?
Free standard AU shipping is included on this item.
Can I buy several for a team?
Yes — get in touch and we will confirm what we can supply as a matched batch, along with business and education pricing.
