Brightness setting not working

Question

Hi,

I cannot change the brightness setting on my laptop (using Windows 10). The change brightness slider is active but nothing changes. The screen brightness remains the same if I set the brightness to 2% or to 100%.

Not sure if this is related to Windows update but, after the las update (on ‎18.‎05.‎2018), because the screen was too dark, I tried to change the brightness and found out that the I can't do it.

Hello,

Please see the below options:

Go to Device Manager by typing in Devmgmt.msc in Run dialog box.

Navigate to Display devices and right click ATI Radeon HD or Similar device you have. Choose Properties.

On the Driver tab, hit rollback Driver to go back to the previous version.

Option 2. Remove drivers completely and Install the the newest ones available from the OEM or the maker.

What you need to do:

Hi,

I cannot change the brightness setting on my laptop (using Windows 10). The change brightness slider is active but nothing changes. The screen brightness remains the same if I set the brightness to 2% or to 100%.

Not sure if this is related to Windows update but, after the las update (on ‎18.‎05.‎2018), because the screen was too dark, I tried to change the brightness and found out that the I can't do it.

Althought there are already replies in this problem, I must contribute my thoughts to this issue. I have the same brightness settings trouble which emerge after win update versio 1803. Since this update yesterday my display brightness stucked in 100 %, so I can say this case prevents efficiently my working. I can´t lower the brightness of a display anymore but I try to repair this issue from the instructions which Community Advisors gave. Again, it´s very possible that I can´t fix this problem by myself because I´m not technologically oriented i.e doesn´t understand all instructions.

So, what I want to do is to phrase a dark concern to all update troubles which are very frequent nowadays and all customers are not able to solve these kind of problems by themselves. This is not the only time when this kind of error emerge after updating

• some kind of troubles occurs frequently. Human/Computer colife with operating system becomes harder and harder. Let alone aged persons who doesn´t have any digital age skills. When this kind of problems occurs for example after updating, there is necessarily no one who is helping older people. However there might be no way to live without properly fuctioning devices in the digitized society.

Answer 4

Before I give troubleshooting steps, I would request you to provide following information -

A. What is your computer's make and model? For example Lenovo T470

B. What is the Windows version and build? (To check this, type winver in Windows Start Search box and click winver)

Thank you for your answer. I tried everything except 3.D. Update driver from manufacturer's website 

because I don't know what driver I should download.
