The Dell Precision 7520 is a mobile workstation laptop released by Dell in March 2017 as part of its Precision line of mobile workstations. Dell Precision is a series of mobile and fixed computer workstations designed for professional consumers and CAD/Architecture/CG professionals, or as small-scale business servers. The Precision series was launched in 1997.

The Dell Precision 7520 includes a 15.6-inch display with a resolution of 1920 by 1080 pixels with an optional touchscreen or an anti-glare LED 15.6-inch display with a resolution of 3840 by 2160 pixels. According to a review of the Dell Precision 7520 by Laptop Mag, the laptop’s 2.8-kilogram or 6.2-pound weight is heavy, even for a workstation. However, the review also found that the Dell Precision 7520 has a ruggedized construction, even though it is bulky for its class. The Dell Precision 7520 includes a metal chassis and a carbon-fiber lid that is tough enough to pass a variety of Military Standard 810G tests. The laptop includes three USB 3.0 ports, including PowerShare for charging devices using the laptop’s battery, an SD card slot, an audio jack, and a Kensington lock slot on the right edge. On the left edge, the laptop includes another USB 3.0 port with PowerShare, a full HDMI output, a mini DisplayPort, a SmartCard reader, and a Thunderbolt 3 port that uses a USB-C connection.

The Dell Precision 7520 includes a 3.9- by 2.2-inch touchpad that includes three mouse buttons (the right and left buttons for right and left clicking, and a center button for scrolling). It also includes a pointing stick just below the home key row and three more mouse buttons just below the spacebar.
