Symptoms

Screen flicker and other reasons to turn off the ambient light sensor.

The Ambient Light Sensor is an automatic feature designed to balance battery life, with optimal display brightness. It does this by detecting the light present in the laptops environment and adjusting the display accordingly. While battery life is increased, there are situations where manually controlling the brightness is desirable.

Anyone familiar with the older location for enabling and disabling the ambient light sensor discovers it all changed in Windows 8.1. Older utilities designed to incorporate the ambient light sensor interface were retired when we went to Windows 8.1. (For Example: Quickset or Backlitkb.exe)

Cause

Note: Updating to the current BIOS on some laptop models may allow this issue to be addressed from the BIOS. (For example: The Vostro 5470 BIOS version A06 added an ON/OFF feature for automatic brightness.)

Resolution

How to disable the ambient light sensor in Windows 8.1
