    ASUSPRO B Advanced Series business notebooks are tested to exceed the demanding US MIL-STD 810G military standard, ensuring extreme reliability. They are designed to meet the needs of enterprise, institutional and government users in a fully-managed IT environment, and offer improved productivity with business-class security and manageability.

    ASUSPRO P Series

    Outstanding reliability

    All ASUSPRO B Series notebooks are strictly quality-tested to much higher standards than mainstream notebooks, to satisfy the reliability and durability demands of business and institutional users. They are tested for durability in drop tests, hinge cycle tests, and panel pressure testing. B-Series notebooks also ship with an anti-shock hard drive that includes a triple protection mechanism to ensure data is always safe.



    Durable carbon-reinforced screen cover

    True-comfort keyboard and precision touchpad

    The screen cover on B Series notebooks is constructed from a durable carbon-reinforced material that is several times stronger than conventional plastics. This allows the notebook to withstand 20% higher panel pressures compared to standard notebooks, affording better damage protection with less weight.

    Subtly stylish

    Extra-strict ASUSPRO reliability testing standards

    Business users demand higher standards and greater reliability, so all ASUSPRO Series notebooks are strictly quality-tested to much higher standards than the industry norm for mainstream notebooks. They are tested for durability in drop tests, hinge cycle tests, and panel pressure testing. They also ship with an anti-shock hard drive that includes a triple protection mechanism to ensure data is always safe.



    Enhanced drop testing
    More than double the drop height of standard notebooks

    Stronger hinge testing
    20,000 more cycles than standard notebook testing

    Enhanced pressure testing
    Up to 20% higher endurance compared to normal notebooks

    Spill-resistant keyboard
    Occasional liquid spillages are no longer a problem

    Anti-shock hard drive keeps data safe

    ASUSPRO B advanced series notebooks offer increased hard drive protection, with damage-absorbing sponge cushions designed to protect the hard disk against shocks and drops during transportation. Additionally, the hard disk features a complete protection mechanism consisting of G-Sensor hardware and software that actively protects against imminent impacts in order to help keep data safe and secure. This system uses a 3D digital accelerometer with three levels of sensitivity: off, normal, and high. The latter is activated by default, and impact detection remains on at all times.

    Designed for professionals

    True-comfort keyboard and dedicated numeric keypad increase productivity

    Notebook keyboards are of great concern in the workplace, as they are essential for comfort and productivity. ASUS engineers have fine-tuned the B Series keyboard, providing optimum key feel and long key travel to maintain comfort during long hours of work. The keyboard also provides a full dedicated numeric keypad, complete with navigation keys, to increase efficiency for data entry or document navigation.

    Ultraportable, subtle, stylish




    47% bigger multi-gesture touchpad

    Large multi-gesture touchpad

    47% bigger multi-gesture touchpad

    The touchpad has been enlarged to 107 x 61mm, matching the screen ratio to aid input and navigation. Larger than touchpads on similar notebooks from other brands, it provides responsive and accurate multi-touch control. With gesture support, it effectively replaces the mouse, offering an alternative and intuitive input option. Multi-touch input allows effortless accuracy without a mouse, including two-finger web page scroll, zooming and rotating images, plus three-finger tapping to mimic a right-click. Workflow can be streamlined with gesture control, especially multi-step tasks such as presentations and research projects.

    47% bigger multi-gesture touchpad


    Anti-glare display for comfortable viewing

    The matte screen surface used in ASUSPRO notebooks prevents unwanted reflections, reducing eye fatigue. It also prevents unsightly fingerprint smudges from spoiling displayed content such as presentations. Ergonomically-angled and textured palm rest areas provide a comfortable and solid feel for optimum productivity.

    Flexible and considerate connectivity options through a separate docking station allow for the quick attachment of peripherals, communication devices, power cables, and adapters.




    Trusted Platform Module for robust, hardware-based security

    Trusted Platform Module (TPM) is a hardware chip integrated on the motherboard that securely encrypts data, reducing the risks posed by hackers looking to capture password and encryption keys to sensitive data. TPM adds an additional layer of security and allows notebooks to run applications more securely, making transactions and communications more trustworthy. When used in conjunction with an optional security software package, it provides greatly improved overall system security, file protection capabilities, and email/privacy safeguards. TPM enables stronger security than that delivered by the BIOS, operating system, or any non-TPM application.

    Improved security with fingerprint scanning

    Fingerprint scanning ensures maximum security and data protection. The electronic scanner in ASUSPRO B Series notebooks uses RF imaging to read fingerprint patterns, which is less affected than other sensor technologies by skin conditions, including dry, worn, calloused, dirty or oily skin.

    TPM data protection

    Smart card-based identification

    Supported on the ASUSPRO B Series, smart cards can be used for identification, authentication, data storage, and application processing. Users can use them for logins or online transaction authorization.

    Smart card-based identification



    Keep data safe, plus trace and locate stolen notebooks

    Protect your data – trace and locate stolen notebooks

    Intel® Anti-Theft Technology and Computrace® LoJack® for Laptops


    The ASUSPRO B Series utilizes Intel® Anti-Theft Technology (Intel® AT) to help disable access to the operating system in the event that your notebook is ever lost or stolen, keeping it safe and secure. Notebooks are also bundled with Computrace® LoJack® for Laptops by Absolute® Software, giving you the power to remotely locate missing notebooks, plus lock and delete data before it falls into the wrong hands. LoJack® for Laptops ‘s dedicated Theft Recovery Team services work in parallel with local police to track down lost or stolen notebooks and bring them back to you.

    USB 3.0 and USB Charger+

    USB 3.0 and USB Charger+ offer ultra-fast transfer speeds and quick device charging

    B Series notebooks ship with USB 3.0 as standard, delivering up to ten times the transfer speeds of USB 2.0. Exclusive ASUS USB Charger+ software easily charges smartphones, media players, and other portable devices even when notebooks are powered off or in sleep/hibernate modes — in a fraction of the time it would normally take.



    Wake-on-LAN (WOL) allows PCs to be turned on remotely via the network

    Wake-on-LAN(WOL)

    ASUSPRO B series have a built-in hardware module on the motherboard that supports Wake-on-LAN (WOL). This allows them to be powered on or woken from sleep mode by a network message via LAN or WAN connections. This feature is invaluable for remote PC maintenance and support.

    Replaceable battery and smart power
    connect alert

    The removable battery pack can be replaced with an optional extended-life battery, and adding an external battery case can even double battery life. It's also easy to replace old batteries when necessary. The PU Series also feature a power connector alert that notifies users if the power supply malfunctions or is disconnected, minimizing the risk of sudden shutdowns and interruptions.
