  • Weight and dimensions may vary according to configuration.
  • Users will need to set a password the first time the device starts up.
  • Specification may vary by model and region.
  • Internet connection required. Google, Google Play, YouTube and other marks are trademarks of Google LLC.
  • 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.
  • The stated width of the side bezel is the distance between the edge of the non-active screen display area and the inside edge of the case. If the case width is included, the side bezel width is 5.7 mm. The stated width of the bottom bezel is the distance between the edge of the non-active screen display area and the visible edge of the display when the laptop is opened to 90°. Measurements are based on the standard (not anti-glare) display configuration.
  • USI Stylus sold separately and will be released at a later date.
  • ASUS Chromebook CX9 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. 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 notebook, then tilting the laptop to drain away the excess liquid, wipe off and let it dry for at least 24 hours.
  • Based on Chromium OS power Load Test. The 14-hour use on a single charge was determined by looping local video playback at higher than 80 nits and at the default display brightness level. Battery performance is based on a mix of standby, web browsing and other use. Charging time requires the battery to be at least 5% charged, with the device inactive and using the included charger. Actual battery life depends on usage, specifications, applications and environment, among other factors.
  • Unless otherwise stated, WiFi and data transfer speeds are based on theoretical performance. Actual performance may vary.
  • Google feature availability varies according to country. Please check with your local ASUS retailer for details. Offer expires and must be redeemed by January 31, 2022.
