Increase And Decrease of Brightness

Hi,

There are several possible reasons why you cannot modify the brightness of your device. It could be a software conflict or a hardware issue. For us to better assist you, we'd like to ask you a few questions:

• Did you encounter any error messages when increasing or reducing the brightness of your laptop?
• Did the issue occur right after you bought the laptop?
• Have you made any recent changes to your device before the problem started?
• When did the issue begin?

We'll wait for your response.

 

When I decrease my brightness it increases and when I increase is decrease.

When I decrease my brightness it increases and when I increase is decrease and when I increase to max it shows black screen and again when I decrease for max(black screen) it is showing very low brightness.
