Human Presence Detection features use AI to automatically lock the screen when the user steps away and wake upon return and Peek Alert provides alerts when prying eyes are detected. By leveraging on-device AI acceleration, these features enable business users to work more effectively, reduce distractions, and maximize productivity in a rapidly evolving digital workplace.

"Businesses today demand smarter, more efficient computing solutions that keep pace with the rapidly evolving digital workplace. The Portégé Z40L-N represents a new era of AI-powered business laptops—one that not only enhances productivity but also redefines how professionals interact with technology," said James Robbins, General Manager, Dynabook Americas, Inc.

AI-Optimized Performance for Business

At the heart of the Portégé Z40L-N is Intel's Core Ultra processor (Series 2), equipped with a powerful new NPU that accelerates AI workloads directly on device, ensuring faster processing, enhanced efficiency, and better security. With Intel® Arc™ Graphics, the laptop delivers smooth visuals and AI-powered performance enhancements, making it ideal for data analysis, video conferencing, and content creation.

The AI-enhanced power management system dynamically adjusts battery consumption based on applications used, allowing for hours of unplugged video conferencing and all-day productivity. A self-replaceable battery extends the laptop's lifespan, reducing IT costs and downtime for businesses.

"By harnessing numerous productivity- and performance-focused applications for edge AI in our latest systems, Dynabook is empowering organizations with unparalleled intelligence, security, and mobility. We're dedicated to pushing the boundaries of innovation to ensure our customers stay ahead in an increasingly intelligent world," Robbins continued.

Built for Business Mobility

Designed for professionals who require durability without compromise, the Portégé Z40L-N is housed in a magnesium alloy chassis that meets MIL-STD-810H standards, ensuring resilience against drops, shocks, and extreme conditions. Despite its thin and ultra-light form factor, the laptop delivers full-size connectivity, including USB-C/Thunderbolt™ 4, HDMI, and USB-A ports, eliminating the need for adapters for maximum convenience.

Smarter, More Secure Workflows

As a Microsoft Secured-core PC, the Portégé Z40L-N prioritizes enterprise-grade security with chip-to-cloud protection, safeguarding sensitive data while enhancing user convenience. Designed to proactively defend against security threats, the device features Peek Alert, which detects unauthorized onlookers and allows users to instantly block the screen with a simple hotkey. Presence Detection automatically locks the laptop when the user steps away and wakes it upon return, reducing security risks while maintaining seamless accessibility. Adaptive Dimming helps optimize power efficiency by detecting when a user looks away, intelligently adjusting the display to conserve battery without disrupting workflow. Additional AI-driven features like Lock on Leave and Wake on Approach enhance security by ensuring the device remains protected when unattended, while Windows Hello fingerprint and face authentication provides a fast, password-free login experience, further streamlining secure access for business professionals.
