All four models include a SATA III SSD (128GB or 256GB), Wi-Fi (b/g/n), Bluetooth V4.0, 0.3MP webcam, a sleeve, VGA and Ethernet adaptors, an audio subsystem incorporating Bang & Olufsen technology, and one USB 2.0 and one USB 3.0 ports. The USB 3.0 port features 'USB Charger+' technology that allows portable devices to be charged ore quickly than usual.
Important ultrabook features include good battery life and quick startup. Asus claims up to 25% longer battery life than other ultrabooks (up to 5 hours for the 11.6in configurations, and up to 7 hours for 13.3in) and standby time of up to two weeks.
System resume time is said to be around two seconds. A useful safety measure is that the ZenBook automatically saves open files when the battery level falls below 5%.
