Compact 15.6-inch mobile workstation

The Dell Precision 5520 is a 15.6-inch performance-class laptop built for professionals who need serious compute power in a thin chassis. Its borderless InfinitiEdge display delivers 1920 x 1080 resolution on a matte LED-backlit panel. An Intel Core i5-7440HQ quad-core processor running at 2.80GHz drives demanding workflows. 16GB of DDR4 memory and a 256GB M.2 PCIe solid-state drive provide responsive multitasking and fast boot times.

Aluminium frame with essential I/O

The precision-machined aluminium body keeps the footprint small for a 15-inch device while surviving daily transport. Two USB 3.0 ports handle peripherals and external storage without adapters. Integrated AC Wi-Fi and Bluetooth maintain wireless connectivity in office or field environments. A built-in webcam supports video calls without extra hardware. The matte screen finish reduces glare under bright lighting.

Fixed memory and single-drive constraint

The 16GB DDR4 capacity is soldered and cannot be expanded beyond the factory configuration. Only one M.2 PCIe slot exists, so storage upgrades require replacing the 256GB drive rather than adding a second unit. The four-core 2.80GHz CPU limits sustained heavy rendering compared to six- or eight-core alternatives. Buyers who need more storage or user-upgradable memory should consider other platforms.

商品問答

What does the USB 3.0 interface limit in practice?

Each of the two USB 3.0 ports runs at up to 5 Gbps, so external storage and peripherals are capped at that bandwidth.

What physical space does the 256 GB M.2 drive need?

The drive uses an M.2 slot inside the chassis; no 2.5-inch bay or caddy is required.

How is the operating system installed, and what step is often missed?

Windows 10 Pro comes pre-installed; the step users sometimes skip is completing the first-boot setup and installing driver updates.
