Dynabook Portégé Z40L-N Now Official, laptop with a replaceable battery

Dynabook has unveiled the Portégé Z40L-N, a premium business laptop featuring a 14-inch 1920 x 1200 display, Intel Core Ultra 7 268V processor, up to 32GB RAM, and 2TB PCIe NVMe SSD storage.

A user-replaceable 65Wh battery. While it’s not hot-swappable, removing a bottom panel allows users to replace it, extending the device’s lifespan—something rare in today’s thin-and-light laptops.

Weighing less than 1kg (2.2 lbs), the magnesium-aluminum chassis ensures durability while keeping it ultra-light. The laptop also meets MIL-STD-810H standards, proving its resilience against drops, shocks, and extreme conditions.

The Portégé Z40L-N is powered by Intel Core Ultra 5 and Ultra 7 processors, with 16GB or 32GB of onboard RAM. While the memory is not upgradeable, users can swap out the SSD (up to 2TB PCIe NVMe).

Ports include:
2 x Thunderbolt 4
2 x USB 3.2 Gen 1 Type-A
1 x Gigabit Ethernet (Intel i1219)
1 x 3.5mm audio jack
1 x microSD card reader

Other features include a 5MP IR webcam with face recognition, WiFi 7, Bluetooth, and a spill-resistant backlit keyboard.

Pricing & Availability
