These folks are right – Our laptop has no options for dimming or adaptive brightness. After doing a registry hack to add them back as options – turning them off did not work anyway. Also tried disabling Intel graphics Power saving option and no luck with that either. Finally did this:
We went to Device Manager -> Batteries -> Microsoft ACPI-Compliant Control Method Battery and right clicked on it. Then we selected ‘Disable Device’.

This worked and has not had any adverse affect whatsoever.

It may not be an option on your computer – ours is a Lenovo x1 Nano.
