Asus has introduced three models in its ExpertBook B Series: B1, B3 and B5, each powered by the latest Intel Core Ultra Series 2 processors and offering enterprise-grade security, durability and AI-ready performance. The B1 family, available in 14″ and 15.6″ FHD variants, is configurable with up to a Core i7-1365U vPro CPU, Intel UHD graphics, two DDR5-5200 SO-DIMM slots supporting up to 64 GB RAM and dual PCIe 4.0 M.2 SSD bays (2280 + 2230).
SurveyPort selection includes two USB 3.2 Gen 2 Type-C (PD + DP), two USB 3.2 Gen 1 Type-A, HDMI 1.4b, RJ-45 and a combo audio jack, alongside Wi-Fi 6 and Bluetooth 5.4. A 42 Wh or 50 Wh battery delivers all-day endurance via USB-C charging (5 V–24 V), while MIL-STD-810H testing, 50,000 hinge cycles and 78 cc spill resistance underscore its resilience. Security features encompass discrete TPM 2.0, a chassis-intrusion sensor, fingerprint/IR login, dual-EEPROM self-healing BIOS and a one-year McAfee Premium subscription.
The B3 series steps up to 14″ and 16″ WQXGA (2560×1600) IPS panels with 144 Hz refresh, 400 nits brightness and TÜV-certified low-blue-light filtering. Configurable up to Core Ultra 7-265H vPro CPUs with integrated Intel Arc and an NPU, these models support 64 GB DDR5-5600 RAM and dual M.2 slots—one doubling as an optional 4G/5G modem bay. I/O expands to two Thunderbolt 4 USB-C ports (USB4, PD, DP), two USB 3.2 Gen 1 Type-A, HDMI 2.1, RJ-45, combi audio, microSD and optional smart-card reader.
Networking includes Wi-Fi 6E and Bluetooth 5.4, and the 50 Wh/63 Wh battery offers up to 11 hours of runtime with quick-charge to 60 percent in 49 minutes. Durability is enhanced by 24 MIL-STD-810H tests, 15,000 USB-C cycles and 30 kg panel-pressure endurance. The ExpertGuardian suite adds Absolute Persistence 2.0 for firmware-level asset tracking.
At the top, the B5 lineup combines all-aluminum, CNC-milled chassis, just 17.9 mm thin and starting at 1.35 kg on the 14″ model, with the same Core Ultra 7 H-series CPUs, Intel Arc graphics and 16-core NPU. Memory and storage mirror the B3, but I/O standardizes dual Thunderbolt 4 ports alongside USB 3.2 Gen 1, HDMI 2.1, microSD, RJ-45 and optional SIM and smart-card slots.
Spill resistance up to 78 cc, 30 kg panel pressure, 10 million keystroke durability and self-healing BIOS ensure long-term reliability. Security is further bolstered by Windows Secured-core certification. All three models ship with AI ExpertMeet for on-device transcription, translation and noise cancellation, and benefit from Asus’s nationwide service network with onsite support in 15,500+ pin codes and international warranty coverage in 80 countries.
