Do you mean the backlight brightness that can be altered by the keyboard shortcuts? If so, when does this happen? Randomly, or at certain times? You have two power profiles, one when the laptop is plugged in, and one when the laptop is unplugged and using its battery power. Go into control panel and select power options, then edit power plan or change plan settings, there you will see the two brightness settings for plugged in, and battery power.
This may or may not help your issue, if not give us some more details about when exactly this is happening.
