DELL Precision 3551 laptop i7-10750H 4GB 1TB Quadro P620 15.6" HD

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.
