The only definitive solution to this problem (rather than disabling various options) is to go windows service and disable the sensor service.
Do the following:
1. Press "Windows Key + R" to open the command menu.
2. Type "services.msc" and press enter
3. Scroll through the list of services and look for "sensor monitoring service"
4. Permanently "Disable" the service.
The "sensor monitoring service" may be used for multiple sensors, but most Dell Laptops have a ambient light sensor that dynamically changes the screen contrast and brightness. This is the only sure way to disable it.
