As of Jan. 7th, 2022. Based on internal ASUS market analysis comparing the size and weight of ExpertBook B9 to competitor products from vendors including LG, HP, Dell, and Lenovo. Actual weight may vary by specifications.
ASUS ExpertBook B9 keyboard is spill-resistant, not waterproof. Water damage is possible if the product is submerged or exposed to large amounts of liquids for long periods of time. The ASUS standard limited warranty does not cover problems resulting from accidents such as water damage. To prevent water damage resulting from large spills or other accidents, ASUS recommends turning off the laptop, then tilting it to drain away the excess liquid and wiping off it and letting it dry for at least 24 hours.
Weight may vary according to configuration.
NFC is optional and its specification varies according to country. Authentication works with FIDO 2 certified cards only.
Trusted Platform Module (TPM) optional.
The same device will offer differing levels of available storage depending on the chosen RAID level. If RAID 0 is used, the system combines the capacity of all SSDs in order to enhance data-transfer speeds. The available storage will equal the combined physical capacity of all the SSDs on the device. However, if the device is configured with RAID 1, two copies of the data are saved simultaneously in order to protect your data if one SSD fails. As a result, the available storage capacity will be half of the combined physical storage capacity, as half the storage is used for backup copies. For example, a device with two 1 TB SSDs in a RAID 0 configuration will have 2 TB of available storage capacity, but with RAID 1 the available storage capacity will be 1 TB.
The testing regime includes the requirements of both military-grade standards and ASUS quality tests, and varies depending on device. MIL-STD-810 testing is conducted on selected ASUS products only. Note that the MIL-STD-810 testing helps to ensure the quality of ASUS products but does not indicate a particular fitness for military use. The test is performed under laboratory conditions. Any damage caused by attempts to replicate these test conditions would be considered accidental, and would not be covered by the standard ASUS warranty. Additional coverage is available with ASUS Premium Care.
Recharges the battery up to 60% within 44 minutes when the system is off or in standby mode. Power adapter with a minimum capacity of 66 watts is required. After charging has reached 60% capacity, charging will return to normal. Charging time may vary +/- 10% due to System tolerance.
Battery tests conducted by ASUS in March, 2022 using the MobileMark^® 2018 Office Productivity scenario. Battery life test configuration: Intel^® Core^™i5-1235U, 8 GB RAM, FHD display, 1 TB PCIe^® 4.0 x4 SSD, 66 Whr. Test settings: WiFi enabled, BT off, the display brightness set to 200 cd/m², NumberPad off, backlit keyboard off. Actual battery life may vary depending on product configuration, usage, operational conditions and power management settings. Battery life will decrease over the lifetime of the battery.
Please note that all versions of NumberPad work only with the Microsoft Windows operating system.
WiFi 6E network card is available on selected models. The connectivity of WiFi 6E band may vary according to the regulation and certification of each country/ region.
ASUS Control Center is optional and its availability varies according to country. Please check with your local ASUS retailer for details.
ASUS management solutions include ASUS Control Center and ASUS Business Manager platform.
ASUS Service Package options include: 24x7 support; MyASUS app; Three-year international warranty; Pick up & return service; Onsite service; Next business day onsite response; Accidental damage protection; Defective HDD retention. Service and warranty coverage may vary depending on country and territory. Service may not be available in all markets. We recommend that you check with your local retailers to confirm the options available.
Note that the supplied accessory box is manufactured from recyclable paperboard. The condition of this material will naturally deteriorate over time and is not covered by an ASUS warranty. Check your accessory box regularly and, when it is no longer suitable to be used as a laptop stand, please dispose of it responsibly.
