Dell Latitude 5590 Ultrabook

The Dell Latitude 5590 is a 15.6 inch business laptop built around an 8th Gen Intel Core i7-8650U quad-core processor. It ships with 8 GB of DDR4 memory and a dual-drive layout that pairs a 256 GB M.2 SSD with a 1 TB secondary SSD. The 1920 x 1080 IPS panel is non-touch and framed by thin borders. Windows 10 Pro comes pre-installed for immediate deployment.

Thermals and power in daily use

The U-series chip runs at a 1.90 GHz base with a 4.20 GHz turbo, keeping heat output modest during typical office workloads. Integrated Intel UHD Graphics 620 handles display output without a discrete GPU, so fan noise stays low when browsing or editing documents. The 45 W power adapter supplied with the unit matches the processor’s thermal envelope for efficient charging.

Build integration and expansion

A USB Type-C port with DisplayPort alternate mode and optional Thunderbolt support drives external monitors or docks. Three USB 3.1 Gen 1 ports, HDMI, VGA and RJ45 cover legacy and modern peripherals alike. An SD card reader and optional SIM tray add field flexibility. The chassis measures 14.8 inches wide by 9.87 inches deep and weighs 4.19 lbs, fitting standard 15.6 inch bags and sleeves.

Questions about this item

How do I install a second M.2 SSD in the Latitude 5590 and which step is often missed?

Remove the base cover, insert the drive into the empty M.2 slot at an angle, then secure it with the screw; the step often missed is pressing the drive fully flat before tightening the screw.

What maintenance will the 256 GB M.2 and 1 TB secondary drives need over time?

Run TRIM periodically in Windows 10 Pro to keep write performance consistent; no mechanical parts require lubrication or replacement.

What limit appears first when the i7-8650U runs at 4.20 GHz boost for extended periods?

The processor reduces clocks once its thermal threshold is reached, so sustained speed depends on the cooling solution rather than a fixed time limit.
