Thermals noise and power in normal use

Dell Optimizer learns usage patterns to extend battery runtime and manage thermal behaviour during typical office workloads. ExpressCharge Boost delivers up to 35% charge in about 20 minutes and up to 80% in an hour. ExpressConnect automatically selects the strongest Wi-Fi access point and prioritises bandwidth for critical applications. The Iris Xe integrated GPU and Tiger Lake core architecture keep power draw modest for productivity tasks.

Dell Optimizer and Express features

Dell Optimizer adapts system performance and battery charging to the user's daily patterns. ExpressResponse uses Intel Adaptix Technology to prioritise frequently used applications so they open faster. ExpressSign-in employs a proximity sensor with Intel Context Sensing to wake the laptop and log in via IR camera and Windows Hello when the user approaches, then locks the device when they walk away. ExpressConnect continuously optimises wireless connectivity for video calls and cloud apps.
