Ready for mobile professionals

The Dell Latitude 5550 is a 15.6-inch business laptop built around an Intel Core Ultra 5 135U processor with twelve cores. It ships with 32GB of DDR5 memory and a 1TB NVMe drive under Windows 11 Pro. The FHD IPS touchscreen reaches 250 nits with an anti-glare coating.

Best for single-device workflows

This configuration suits users who want one machine for office applications, video calls and light creative tasks thanks to the integrated Intel Graphics and 1080p IR webcam with privacy shutter. Buyers who need discrete graphics performance for rendering or gaming should look at a different system.

Verify port and display needs

Confirm that two Thunderbolt 4 ports, HDMI 2.1, Ethernet and an SD slot match your docking and peripheral requirements. The 60 Hz panel covers 45% NTSC, so colour-critical work may need an external monitor. Check that Windows 11 Pro 64-bit meets your software licensing.

商品問答

Does the 15.6" FHD Touchscreen need a Thunderbolt 4 dock to run two extra 4K monitors?

Yes, the two Thunderbolt 4 ports and the HDMI 2.1 port together support up to three external 4K displays, so a compatible dock or adapters are required for multi-monitor setups.

Will my existing USB-A peripherals work with the 2x USB Type-A ports on this Latitude 5550?

The laptop includes two USB Type-A ports, so standard USB-A mice, keyboards, flash drives and other peripherals connect directly without adapters.

How can I confirm the Intel Core Ultra 5 135U is using its NPU for AI tasks after setting up Windows 11 Pro?

Open Task Manager, select the Performance tab, and look for an NPU entry showing utilisation graphs when Copilot or other AI features are active.
