“Keep WiFi on during sleep” setting for Chromebooks. ‘Lucid Sleep‘ keeps your Chromebook connected during naps (sleep mode).
Getting back to work after awaking your Chromebook from its digital slumber (sleep) 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 Chromebook is powered down so that it can stay better synced with the rest of your devices and data.
It will, for example, allow your Chromebook to temporarily awake itself (turn on WiFi) and connect to a new wireless hotspot if you change 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 Chromebook screen. You can turn on this feature and try it for yourself by toggling on the “Keep WiFi on during sleep” in the Privacy settings menu on your Chromebook.
The question is should you enable or disable the “Keep WiFi on during sleep” setting for Chromebooks?
The simple answer is how much do you appreciate longer battery life? If you choose longer battery life then consider disable “Keep WiFi on during sleep” option. At the end of the day, its a matter of preference.
1) Open your Chromebooks privacy settings page.
a. Click on the bottom right hand side of your Chromebooks display. (time, notification area, etc…) A small pop-up box will appear (in my case the box is black). Click the rounded gear icon 
to open the Chromebook settings window.

Sometimes you need to balance your battery life and make it last longer. You dont always need Google Chromebook to automatically fetch updates and constantly keeping your device synced even in sleep mode.
