‘Lucid Sleep’ keeps your Chromebook connected during naps
Getting back to work after waking your Chromebook Pixel from its digital slumber is about to get a bit easier. Google announced that its new (still experimental) Lucid Sleep feature is now available. This setting maintains limited Wi-Fi connectivity when the machine is powered down so that it can stay better synced with the rest of your devices and data. It will, for example, allow your Pixel to temporarily rouse itself and connect to a new wireless hotspot if you move locations. It can also update push notifications and app data so that everything is up to date and ready to go as soon as you flip open the screen. You can turn on this feature and try it for yourself by selecting “Keep WiFi on during sleep” in the Privacy settings menu.
