Dell Latitude 7420 — 14" 4K UHD Business Ultrabook

The Dell Latitude 7420 pairs a razor-sharp 4K UHD IPS display with Intel's 11th Gen Core i5-1145G7 processor and 16GB of soldered LPDDR4x RAM — all wrapped in a slim 18mm chassis weighing just 1.31kg. Every unit is professionally tested by Reboot IT and backed by a 12-month warranty.

Key Benefits

• Stunning 4K UHD display: 3840×2160 IPS anti-glare panel delivers pin-sharp detail ideal for design work, data-heavy spreadsheets, and video calls.
• 11th Gen Intel Core i5-1145G7: Quad-core processor with Intel Iris Xe graphics handles everyday business workloads and light creative tasks without breaking a sweat.
• 16GB LPDDR4x RAM: Soldered low-power RAM keeps multiple browser tabs, Office applications, and video conferencing running simultaneously with no slowdown.
• 256GB NVMe SSD: M.2 2230 PCIe solid-state drive boots Windows in seconds and transfers files at full NVMe speed.
• Thunderbolt 4 × 2: Dual TB4 ports support 40Gb/s data transfer, dual 4K external monitors, and 65W USB-C charging from a single cable.
• Travel-ready build: At 1.31kg and 18mm thin, the magnesium-alloy chassis fits any bag and survives the commute — MIL-STD-810H rated for drops, dust, and temperature extremes.

Performance in Use

For the professional who needs pixel-perfect output on the road, the Latitude 7420 shines. The 4K IPS panel renders spreadsheet rows and PDF documents with near-print clarity, so you can review contracts and financial models without zooming. The i5-1145G7 runs cool and quietly through sustained document-intensive sessions, while Intel Iris Xe handles Teams video calls, screen sharing, and light Photoshop edits without dropping frames.

Back at the desk, a single Thunderbolt 4 cable docks the laptop to an external 4K monitor, charging it at the same time. The second TB4 port stays free for a high-speed NVMe enclosure or daisy-chained display. Wi-Fi 6 (802.11ax) keeps data flowing on congested office networks, and Bluetooth 5.1 pairs instantly to headsets and mice.

The 63Wh battery comfortably covers a full working day of mixed use — expect 7–9 hours in typical conditions. When you do need to top up, the compact USB-C charger slips into any bag pocket, replacing the need for a bulky barrel-plug adapter.

Frequently Asked Questions

Does this laptop support Windows Hello?

Yes. The Latitude 7420 includes both an IR webcam for face recognition and a fingerprint reader, so you can log in instantly without typing a password.

Can I connect two external 4K monitors?

Yes. The two Thunderbolt 4 ports each support DisplayPort Alt Mode, and the HDMI 2.0 port provides a third video output — giving you a total of three displays (including the built-in screen) at once.

Is the RAM upgradeable?

No — the 16GB LPDDR4x is soldered to the motherboard. This is standard for ultra-thin business laptops and keeps the chassis slim and power-efficient. For most professional workloads, 16GB is sufficient.

What is the storage upgrade path?

The M.2 2230 PCIe NVMe slot is user-accessible. You can swap in a 512GB or 1TB 2230 SSD to expand storage without replacing the entire unit.

Does it ship with a charger?

Yes, each unit is supplied with a compatible USB-C/Thunderbolt charger. Any 65W USB-C PD charger is also compatible.

How is shipping handled?

Free standard AU shipping is included. Express delivery options are available at checkout. Orders are dispatched from our Melbourne warehouse, typically same or next business day.

What does the 12-month warranty cover?

The warranty covers hardware defects and failures for 12 months from purchase, including a 30-day battery capacity guarantee. It does not cover accidental damage. Contact our Melbourne team for any warranty claims.
