The ASUS ZENBOOK UX21E is meticulously designed and engineered to achieve the thinnest profile and lightest form factor of any ultrabook, all while accommodating the latest technology in a harmonious marriage of power and art. Elegant and durable aluminum with a hairline spun finish reflects a cool, infinite look of limitless depth. The ASUS ZENBOOK™ UX21E measures a minimum thickness of only 12" and weighs only 2.43lbs.
Exclusive ASUS Super Hybrid Engine II with Instant On enables 2-second resume of the notebook from sleep, with up to two weeks of standby time with open files and other pending data kept safe in memory. Plus, automatic data backup when the battery reaches 5% charge further helps secure your work. The ASUS ZENBOOK UX21E keeps energy saving front and center with a dedicated Battery Saving Mode, which conserves power whenever possible to increase battery life by as much as 25%.
You're also always in the know when it comes to the battery thanks to ASUS PowerWiz, a utility that shows exactly how much charge is left per application -- web browsing, gaming, movie watching and more. The ASUS ZENBOOK UX21E combines power, efficiency, smooth usage and user empowerment, all on in one sleek package.
ASUS is proud to deliver the world's first ultrabook with SATA 128GB solid state storage, making for an amazingly smooth and fast computing experience. Additionally, the ASUS ZENBOOK UX21E ships with SuperSpeed USB 3.0 as standard, multiplying the transfer rates of current USB 2.0 by as much as a factor of ten.
Another ASUS exclusive, SonicMaster technology was co-developed with Bang & Olufsen ICEpower to deliver breathtaking, lifelike audio that far exceeds the limitations of conventional notebook PC sound performance. Deeper, more impactful and wider in range, SonicMaster delivers four times the sound output of other ultrabooks without increasing the size or weight of the form factor.
