1. Testing conducted by Acer using Google Chrome OS power_LoadTest. Battery life will vary and the maximum capacity of the battery will naturally decrease with time and usage. See http://www.chromium.org/chromium-os/testing/power-testing for test details.
2 802.11ac 2x2 160 MHz enables 1733 Mbps maximum theoretical data rates, 2x faster than standard 802.11ac 2x2 80 MHz (867 Mbps) and nearly 12x faster than baseline 1x1 BGN (150 Mbps) Wi-Fi as documented in IEEE 802.11 wireless standard specifications, and requires the use of similarly configured 802.11ac wireless network routers or better. To achieve Gigabit wireless speeds, the network requires a wireless router/access point that supports 160 MHz channels.
3 Starting from 2021, availability of the MicroSD Card Reader feature on this Chromebook device may vary depending on model and/or region.
