Business-ready 14-inch laptop

The Dell Latitude 7490 delivers a 14.0 inch Full HD anti-glare display, an Intel Core i7-8650U processor at 1.90 GHz, 16 GB DDR4 memory and a 256 GB SSD. Windows 10 Pro 64-bit is pre-installed. Integrated Intel UHD Graphics 620 uses shared system memory. The magnesium-alloy chassis weighs 3.11 kg and measures 0.69 x 8.7 x 13.03 cm.

Sustained workload thermal profile

The U-series processor maintains its base 1.9 GHz clock during extended office tasks such as document editing, video calls and browser-based applications. Shared graphics memory means frame-buffer pressure rises with heavy multitasking, so the 16 GB DDR4 ceiling matters for stability. Dual-fan cooling keeps surface temperatures comfortable for lap use over multi-hour sessions.

Upgrade path from older ultraportables

This configuration replaces 8 GB dual-core ultraportables that struggle with concurrent video conferencing and large spreadsheets. The jump is worthwhile when daily work routinely exceeds 8 GB RAM utilisation or when a 256 GB SSD eliminates the need for external drives. Buyers needing discrete graphics, touchscreen input or more than 32 GB memory should consider other models.

Questions about this item

How much fan noise and heat does the Core i7-8650U generate during all-day use?

The 1.9 GHz processor uses integrated Intel UHD Graphics 620 and shares system memory, keeping thermal output modest for typical office workloads.

Which cables or peripherals are required to start working with the 14.0" FHD display and ports?

The laptop includes a DC-in power adapter, HDMI 1.4, three USB 3.1 Gen1 ports, DisplayPort over USB Type-C, RJ-45 Ethernet and an SD 4.0 card reader, so only a power cord is essential.

Will my existing DDR4 SODIMM modules work alongside the installed 16 GB memory?

The system has two DDR4 slots supporting up to 32 GB total, so compatible DDR4 SODIMMs can be added to the factory-installed 16 GB.
