Precision 3551 mobile workstation

The Dell Precision 3551 is a 15.6-inch mobile workstation built around a six-core Intel Core i7-10750H processor with a 5.0 GHz turbo frequency. It ships with 4 GB of memory, a 1 TB hard drive and an NVIDIA Quadro P620 graphics card with 2 GB of dedicated video memory. Windows 10 Pro comes pre-installed on the HD-resolution non-touch display.

Installation and common issues

As a complete laptop, the unit requires no internal assembly; simply connect the power adapter and press the power button. Memory and storage upgrades involve removing the bottom cover, which uses standard screws but may need a plastic pry tool to release the clips without damaging the carbon-fibre chassis. The 4 GB of soldered memory cannot be expanded, so the single SO-DIMM slot is the only path to more RAM.

1366 x 768 HD display resolution

The panel resolution is 1366 x 768 pixels, which determines the amount of on-screen workspace and the sharpness of text and CAD geometry. Buyers who need a higher pixel density for detailed visualisation or multi-window layouts should look for a model with a Full HD or 4K panel, as this screen cannot be changed after purchase.

Questions about this item

How can I confirm the Nvidia Quadro P620 2GB GPU is active after setup?

Open Device Manager and verify the Quadro P620 appears under Display adapters; run the Nvidia control panel to confirm driver version and 2 GB dedicated memory are reported.

What accessories are included in the box and what must I purchase separately?

The laptop ships with a power adapter; memory card reader, SIM slot, headphone jack, USB 3.2, HDMI, RJ-45, lock slot and Thunderbolt ports are built in — add external storage, dock or monitor cables as needed.

Which configuration should I choose between the 4 GB RAM and 1 TB drive for professional graphics work?

The 1 TB hard drive provides ample project space, while the 4 GB memory will limit large assemblies; plan to upgrade RAM after purchase for smoother CAD and rendering performance.
