Improve productivity with Dell Precision Optimizer

Intelligence that matches yours

Dell 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.
Private, secure, productive

Private, secure, productive

Productivity at your fingertips: The optional 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. 

Precision, meet privacy: A new feature for all Precision workstations, a camera shutter that ensures others can’t see you through the lens. You can now manually close the shutter for privacy or open it when you want to video conference or take photos.
