Yoga 2 Pro - Windows 10 driver for video does not work - error code 43 -- no brightness control

2015-09-15, 20:43 PM

Upgraded from 8.1 (screen working fine) to windows 10. Post that I have been unable to change brightness in my laptop (it is stuck on maximum brightness which medically taking a heavy toll on my eyes), not only do the physical keys on the keyboard placed for brightness not work but the option to adjust brightness on the personalize window within the control panel is altogether missing!!

 

I can't install the 8.1 driver as it says "my computer does not meet the minimum requirements" for that driver, and the 10.0 driver gives me an error 43 in Devices.

 

Anyone got a good working video driver?

yoga 2 pro.  i5 processor.  Brightness worked fine with windows 8.1  Upgraded to 10 and also upgraded BIOS to 76CN43WW (8/13/2015).  trying the Intel Graphics Driver 10.18.15 .4240 (7/15/2015), wont install with the error 43.   tried to roll back to the 8.1 graphics driver  10.18.10 .3496   (8/12/2014), same problem. 

 

I used the 8.1 graphics driver  10.18.10 .3496   (8/12/2014) when it was on win 8.1, and that worked fine.  Since windows 10 I have this problem and I don't know where to find the logs to see what error 43 means and take the next step.

Have you tried to uninstall the existing HD Graphics driver, reboot, and let windows update install a working driver? I m using the windows update version and it works very well, including all the keyboard controls (I haven't tried external monitors so can say either way on that).

Hi Georgia,

 

yes I have tried uninstalling and re-installing the driver several times, no luck.  I have tried Intel HD Graphics Family driver, version 10.18.15.4240, .4256, and .4279 -- all have the same error code 43.  Looking at events, all events seem to finish successfully.  

 

I am thinking this could be a result of the BIOS upgrade? I upgraded it to 76CN43WW at the same time I upgrded to Windows 10.  

 

What I am really wondering -- do we have anyone that has a yoga2 pro running HT Graphics Family driver on Windows 10 successfully? If so, what Bios are you using?
