Display and keyboard backlight troubleshooting
Context
The device has one LED driver that provides current for the display backlight.
The brightness of the display is adjusted by the Ambient Light Sensor (ALS).
You can enable/disable ALS with the help of Phoenix service software.
Display brightness can be adjusted manually, if ALS is disabled. If the ambient light sensor is enabled, it
adjusts the display brightness automatically.
