Windows 10: The laptop's brightness decreases when I play a video or game without pressing anything and...

The laptop's brightness decreases when I play a video or game without pressing anything and the brightness button is all the way down. What is the solution?

:)

 

Laptop brightness automatically decreases to zero but if I press refresh, backspace, enter, shift or spacebar keys it stops decreasing

I have turned off automatic display brightness and I don't think it is a display hardware issue as when I started the BIOS i didn't have any changes in brightness. I got an old Lenovo Ideapad Yoga 13 windows 8 i5-3337U and 4gb ram working after maybe a year of non-usage. The battery is fine it works after unplugging the charger also. Now that those details are out of the way here is the problem.

Now the problem is that as soon as I start the laptop the brightness just decreases in steps all the way to zero. If i try to increase the brightness by pressing the button it decreases again at the same rate so I have to hold the brightness up button for it to be maximum then if I press backspace, refresh, enter or spacebar keys it stops decreasing and everything is normal. After that if i press any of the number keys or brightness decrease key (f11) it again starts to decrease. Please suggest a solution I'm at the end of my wits here.

Can not control the laptop brightness

Hi Dinh,

Thank you for posting your query in Microsoft Community.

I understand the inconvenience you are facing currently.

I would appreciate if you can provide us the following information to help us understand the issue better.

What happens when you try to change the screen's brightness?

For a majority of laptops, there isn't a control for setting the contrast. However, you can set the brightness of many laptops by pressing and holding the Fn key, and then pressing a function key to decrease brightness
or increase brightness.

I suggest you to uninstall the display driver from your computer and then install in Compatibility mode.

To uninstall the driver follow the steps given below.

• 
  Press Windows key + X and select
  Device Manager.
  
• 
  Search for Display Adapter
  and expand it.
  
• 
  Right click on the Display Adapter
  and select Uninstall.
  
• 
  Do not restart your computer.
  

Once you have successfully uninstalled the driver, please install the driver in compatibility mode following the steps given below.
