Cleverly, the bulb only works when your reading device is actually on and does not work when it is
in screensaver mode.
This means that when you download a file, leave the machine to go
into screensaver mode or are on the front page you'll see an advertisement.
Select «Screensaver» in the left - hand navigation column and then, within the screensaver menu, select «
Screensaver mode».
Another nice touch of the camera app is if you leave it open without taking photos or recording it will go into
a screensaver mode just to save a little on the battery.
You could still use
the screensaver mode and choose it to work with charging only or both charging and a dock.
When you're not actively streaming something to the Chromecast, it will enter
a screensaver mode that can display images from Google Photos, Facebook, Flickr, curated artwork, the weather and even headlines from top news sources.
