Built to power your ideas
Small yet mightyDesigned to impress: Performance has never looked better on Dell’s thinnest and lightest mobile workstation. The sleek, compact design fits a 15.6-inch display into a 14-inch frame and is now available in two colors.
Show off your work: An InfinityEdge display with up to an OLED PremierColor ensures brilliant, virtually borderless viewing.
Enhanced viewing: Upgrade to an optional UHD touch screen that features 100% Adobe RGB with either 500nits or an OLED display with 100% DCI-P3.
Quick office integration: Thunderbolt™ 3 Type-C with x4 PCIe and HDMI 2.0 ports enable 4K video connectivity at 60 frames per second.
Stays cool: A revolutionary cooling system with dual fans improves airflow and keeps your system cool under heavy workloads.
Seamless sign-on: The optional Windows Hello fingerprint reader ensures that you and only you can access your work. Simply place your finger on the sensor and just like that, you’re ready to take on the next task. Or upgrade to the Windows Hello IR Camera and sign on with one look.
Intelligence that matches yoursDell Optimizer for Precision is a built-in AI platform that learns how you work and continuously adapts to your style to create a smarter, more personalized and productive experience.
ExpressResponse: Launch your most used apps faster. We use built-in AI and Intel® Adaptix™ Technology to adjust performance levels where you need them most.
ExpressSign-in: Get to work faster than ever. Our workstation proximity sensor enabled by Intel® Context Sensing Technology detects your presence to instantly wake and log you in via the IR camera and Windows Hello, all without lifting a finger. It locks upon walking away, so your work stays safer.
ExpressCharge: AI improves battery performance by adapting to your typical power consumption and charge patterns. Always on the go? You’ll get an ExpressCharge Boost to gain 35% charge in about 20 minutes. Have more time? ExpressCharge will automatically get you up to 80% in an hour.* And if you can’t charge your system right away, it will subtly adjust settings to preserve resources, such as dimming your screen or turning off Bluetooth when not in use.
Intelligent Audio: Dell Optimizer’s Intelligent Audio will automatically tune your system by adjusting background noise, managing speech volume and refining overall sound experience so you can hear and be heard better wherever you work.
