ASUS ExpertBook B1 (B1503) 15.6-inch Business Laptop
The ASUS ExpertBook B1 B1503CVA-S78673X (part number 90NX0801-M09XT0) is a 15.6-inch business laptop with the Intel Core 7 150U processor, 16GB of DDR5 memory, a 512GB PCIe 4.0 NVMe SSD and Windows 11 Pro.

This configuration ships with a 720p HD camera, a 42Wh battery, and a carry bag plus wired USB optical mouse in the box.
Intel Core 7 150U Processor
The Intel Core 7 150U has 10 cores and 12 threads, boosts up to 5.4 GHz and has 12MB of cache, with integrated Intel UHD Graphics. It is a low-power U-series chip suited to Microsoft 365, web applications, ERP and accounting software, and video meetings.

The 15.6-inch Full HD (1920 x 1080) panel is anti-glare and rated at 300 nits, with 170-degree viewing angles. The larger chassis leaves room for a backlit keyboard with a dedicated numeric keypad.
Upgradeable DDR5 Memory and Expandable Storage
The 16GB of DDR5 is fitted in SO-DIMM slots (two in total), so memory can be expanded later. The 512GB M.2 2280 PCIe 4.0 SSD is joined by a spare M.2 2230 PCIe 4.0 slot with an SSD housing for adding storage.
Ports for the Office
Ports include RJ45 Gigabit Ethernet, two USB 3.2 Gen 2 Type-C ports with display output and power delivery, two USB 3.2 Gen 1 Type-A ports, HDMI 1.4 (up to 3840 x 2160 at 30Hz) and a 3.5mm combo audio jack. Wireless is Wi-Fi 6E with Bluetooth 5.4.
Security and Durability
A fingerprint sensor is integrated into the touchpad, the webcam has a physical privacy shutter, and the platform includes TPM 2.0, Microsoft Secured-core PC features, Intel BIOS Guard and Boot Guard, and a Kensington Nano security slot. The chassis is tested to US MIL-STD 810H, and ASUS lists EPEAT Gold with Climate+, ENERGY STAR 8.0 and TCO Certified for this configuration.
