E545 Brightness not adjusting

When I open my E545 laptop after sleeping, I find that the brightness hotkeys do not work (other hotkeys, like for volume, do work). Only after disabling and reenabling my display adapter, or restarting the computer entirely, do the brightness hotkeys work again. I have had a similar issue on another ThinkPad Edge, E530). This has really been bugging me since I got the computers! I see that there was a BIOS update but am not sure that this will solve my problem (or if it could create other problems worse than stuck brightness). Has anyone experienced this issue and/or gotten it resolved?

Re: E545 Brightness not adjusting

Hi Maisymouser,

 

Welcome to Lenovo Community!

 

As per the query, we understood that you are facing an issue with Display brightness on your ThinkPad E545.

 

Have you checked updating graphic driver & Lenovo power manager application?

You can also use ThinkVantage system update utility to check for the latest drivers and application for your system.

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Re: E545 Brightness not adjusting

Hi again, it looks like the solution provided ultimately hasn't fixed my
problem. My brightness function keys are non-functional again. Any new
advice?

Hi Maisymouser,

 

Thank you for the reply!

 

Please go to the AMD Vision Engine Control Center (top option), hit PowerPlay, and disable Vari-Bright!

 

Hope this helps.
