If you still have trouble after trying these steps, contact your Chromebook manufacturer.
#BRIGHTNESS CONTROL ON CHROMEBOOK MANUAL#
We should be able to enable/disable it on the fly and make manual adjustments without disabling the automatic settings. In the future, we’d love to see a more mobile-like approach to automatic brightness. At least Chromebooks start quickly, so there’s that. But it does help to understand why things work the way they do. Yes, it’s a simple solution-albeit a slightly annoying one. If you want to keep it enabled, you then have to avoid making manual adjustments. In the end, the only way to re-enable automatic brightness is to reboot the system. That feature was removed in the latest build and the system now uses the guidelines we talked about in the previous section when determining the appropriate brightness levels at boot. In previous builds of Chrome OS, the automatic brightness setting would actually survive rebooting, so the last-used brightness level got re-applied at boot. Under 'Display,' turn Enable docked magnifier on. In the 'Accessibility' section, select Manage accessibility features. That said, brightness will change instantly as you change the power state: plug in the Chromebook, and the brightness goes up. To magnify the top section of your screen, press Ctrl + Search + d or press Ctrl + Launcher + d. You won’t notice a gradual response to subtle environmental changes like you do on your smartphone. Devices that don’t have light sensors will default to the “less than 400 lux” settings. If the lux is lower than 400, it’ll set to 80% on AC power and 63% on battery. If the lighting in the area is more than 400 lux- a unit in which light is measured in a given space-and the system is on AC power, the brightness is automatically set to 100%. This is all controlled by a deamon called “powerd”-the Chrome OS Power Manager. After that, it checks a few more variables-like general lighting and whether the system is on AC power or battery-then sets the brightness to specific parameters based on what it finds. At boot, the system automatically sets the display brightness to 40%, then adjusts accordingly as the system starts. The phone uses your preferred brightness as a baseline, then adjusts up or down accordingly as the environment changes.Ĭhromebooks don’t really work like that, because the way they judge brightness isn’t nearly as granular.īy that, we really mean Chromebooks only use a few discrete settings.

Most modern smartphones allow you manually adjust the display brightness and use the ambient sensor at the same time. How Ambient Light Sensors Work on ChromebooksĬhromebooks are a little bit different from your smartphone.

The opposite happens in sunlight or a bright room. For example, in a dark room, the display dim to be easier on your eyes and the keyboard brightens so you can see it better. That sensor monitors the ambient light wherever you are, then adjusts the display brightness and keyboard backlight accordingly. The same rule applies to Chromebooks (or other laptops that have this feature). But if you’re rocking a modern, premium smartphone, the sensor should be pretty easy to spot. It’s worth keeping in mind that not all phones have these-especially if they fall into the “affordable” price spectrum.

If you look closely on the top bezel of your phone, for example, you’ll like see a few little void areas-one of these is likely the ambient light sensor. The light senors usually hang out somewhere at the top of the device (regardless of whether it’s a tablet, phone, or laptop)-typically near the camera.
