TAIPEI, Taiwan, February 24, 2025 — ASUS today announced the all-new ExpertBook B5 laptop series (B5405/B5605) — a lightweight, AI-enhanced marvel powered by the latest up to Intel® Core™ Ultra processors (Series 2) with Intel vPro® and built-in Intel Arc™ graphics, ushering in a new era of productivity. Packed with cutting-edge AI capabilities, including a dedicated NPU, ExpertBook B5 is built to streamline complex business tasks and accelerate productivity — especially during video calls, with exclusive ASUS AI ExpertMeet delivering optimized audio, video and real-time transcription for seamless collaboration.
Engineered for professionals who demand both performance and security, ExpertBook B5 is protected by ASUS ExpertGuardian, an enterprise-grade security suite that safeguards data, user identities and system integrity with multi-layered protection. With an up to 15 hours[i] battery life for all-day performance on the go, this durable, MIL-STD-810H-tested business laptop empowers uninterrupted productivity.
ExpertBook B5 also underscores the ASUS commitment to sustainability with the integration of a Digital Product Passport (DPP), providing transparent lifecycle tracking and reinforcing responsible environmental practices.
Performance redefined with AI: Up to 99 total-platform TOPS and ASUS AI ExpertMeet
ExpertBook B5 embraces cutting-edge AI with a dedicated NPU delivering 13 TOPS and up to 99 total-platform TOPS[ii] for enhanced multitasking, performance and productivity, and levelling up security. Powered by Intel Core Ultra processors (Series 2), it enables complex market analysis for informed financial decisions and seamless content creation. To support AI-driven workplaces, exclusive ASUS AI ExpertMeet elevates meeting experiences with noise-canceling audio and camera, and AI-generated transcripts, summaries and live-translated captions — all processed on-device to keep business data secure.
ExpertBook B5 packs the latest AI power into a sleek, lightweight and durable all-aluminum frame that weighs just 1.36kg.[iii] With up to 64GB of memory and dual SSDs supporting up to 2TB storage with RAID functionality, it ensures speed, reliability and flexibility. Engineered to MIL-STD-810H military standards and adhering to the rigorous ASUS Superior Durability Test regimen, B5 withstands extreme conditions, minimizing maintenance and maximizing productivity for business efficiency.
Uncompromising design: Ultra-detailed 2.5K, 144Hz display and ASUS ExpertCool thermals
ExpertBook B5’s design prowess goes much deeper than its lightweight, all-aluminum frame. Its ultra-detailed 2.5K 14-inch or 16-inch display, featuring a blazing-fast 144Hz refresh rate and 400 nits brightness, elevates professional viewing and visual computing experiences. Engineered for sustained performance, the newly-enhanced ASUS ExpertCool thermal solution ensures optimal cooling at 40W, even during extended usage. This advanced system includes fluid dynamic bearing fans for a 50%-longer lifespan, thinner heatsink fins for 26%-better airflow – and incorporates a mesh dust filter to maintain long-term performance and reliability.
ASUS ExpertGuardian: Enterprise-grade security
Security is a key concern for modern organizations, which is why ExpertBook B5 is protected by ASUS ExpertGuardian — an exclusive business-focused solution security. Features include cloud recovery with factory image restoration and built-in antivirus software to protect the computer from malware and other threats. Windows 11 Secured-core PC technologies[iv], such as Core Isolation and Memory Integrity, work alongside a discrete TPM 2.0 chip[v] to fortify OS-level security, ensuring encryption key protection and compliance with Trusted Computing Group (TCG) standards. Multi-factor authentication, including biometric FIDO2 login and Match-on-Chip fingerprint recognition, further safeguards access while minimizing security risks.
On-device security and hardware access protection are reinforced with advanced safeguards such as a NIST SP 800-155-compliant dual BIOS with self-recovery and rollback prevention, certificate-based authentication and enhanced password policies to mitigate firmware threats. A built-in smart card reader[vi] provides secondary authentication, while tamper detection and USB access lock features prevent unauthorized manipulation of physical hardware. With up to five years of security updates and BIOS protection, ExpertGuardian ensures long-term device reliability and enterprise-grade protection against evolving cyber threats.
Flexible configurations: Streamlined IT management
Managing large-scale deployments can be complex, so ASUS simplifies matters by allowing ExpertBook B5 to be customized before delivery, enabling rapid deployment of pre-configured PCs tailored to business needs — ready for immediate use. With factory-integrated BIOS settings, asset labeling, laser etching and software imaging, IT teams can standardize configurations efficiently. B5 also benefits from modular design features, including a tool-free battery latch, ensuring easy maintenance and reducing both downtime and overall costs. Backed by enterprise-grade security from ASUS ExpertGuardian and comprehensive lifecycle services, ExpertBook B5 delivers a seamless, streamlined and scalable solution for modern IT environments.
Digital Product Passport: Driving the circular economy with ASUS
ASUS is at the forefront of the Digital Product Passport (DPP) revolution, integrating this cutting-edge initiative to accelerate the shift toward a circular economy. By digitizing critical environmental and sustainability data, ASUS DPP enhances transparency, traceability and accessibility throughout the entire product lifecycle — from material sourcing and manufacturing to recycling and end-of-life management. This valuable information is accessed simply by scanning a QR code affixed to the base of ExpertBook B5.
This innovation empowers businesses, consumers and policymakers with accurate, real-time information to make informed, responsible decisions. Through enhanced resource efficiency, lifecycle tracking and compliance with sustainability regulations, ASUS DPP supports eco-conscious product design, responsible procurement and waste reduction. This ultimately shapes a more sustainable, transparent and accountable technology ecosystem.
