What could be the cause of this issue in the following case?
Jessica is interning at the IT help desk and while your boss is away on vacation he assigned you to mentor her and provide senior leadership. Jessica asks for your advice when she receives a call from one of the executives, who says her laptop screen is appearing really dim and that she can’t remember making any changes.
The most common causes of dim screens have nothing to do with faulty hardware. It is normally triggered by the brightness settings on the monitor or the video card being reset or changed. Another typical scenario, particularly with laptops, is that power-saving mode can be activated when the battery life falls below a certain level.
