Dynabook Americas, Inc. has introduced its new Portégé Z40L-N ultra-lightweight Copilot+ business laptop. Most notably, it has a user-serviceable battery.
Designed for mobility, the Portégé Z40L-N has a 14-inch screen, weighs under 1kg, and comes housed in a durable MIL-SPEC alloy chassis.
It comes loaded with the latest Intel Core Ultra processors (Series 2) with four-times more powerful Neural Processing Unit (NPU) for AI acceleration, Wi-Fi 7, Intel Arc graphics, and AI-enhanced features designed to streamline workflows, enhance collaboration, and improve efficiency.

For example, there are Live Captions, which automatically transcribes audio into text on the screen in real-time, allowing you to read captions for any audio playing on the computer. Dynabook’s exclusive Gesture Control enables touch-free navigation, allowing professionals to switch slides, control media, and navigate presentations with simple hand gestures.
Windows Studio Effects uses AI to automatically enhance video calls with background blur, auto-lighting adjustments, and eye contact correction. Human Presence Detection features use AI to automatically lock the screen when you step away and wake upon return and Peek Alert provides alerts when prying eyes are detected.

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.
Designed for professionals who require durability, 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.

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. Adaptive Dimming helps optimize power efficiency by detecting when you look 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.
The Portégé Z40L-N is backed by Dynabook’s three-year warranty for EZ-Buy models and four-year warranty for Built-to-Order models. Dynabook’s +Care Service warranty with on-site support is also available as optional coverage to minimize downtime in the event of a system issue.
