DESLL use built-in AI and Intel® Adaptix™ Technology to adjust performance levels where you need them most. AI improves battery performance by adapting to your typical power consumption and charge patterns. Express Charge 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. 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.
