Brightness on Lifebook AH532 not working, Windows 7

Postby alich90 » Wed Mar 13, 2019 9:53

Hello!

I have a Lifebook AH532 running Windows 7 64-bit. I noticed in the last couple of days that the brightness control stopped working. Neither the function keys nor adjusting it via "Power options > Screen brightness" seem to work. I am unsure if it is related, but it could be due to an update I installed a week ago which was for the Battery Charging Control as described in this link. https://forum.ts.fujitsu.com/forum/viewtopic.php?f=95&t=45832
If that is INDEED the issue, can anyone guide me in how to roll back to a previous BIOS version where the brightness control would work again? And if not, has anyone been through this issue and was able to resolve it?
Thank you!

I have the same problem after upgrading the BIOS due to the battery charging issue.
Windows 10 x64.

Tried to upgrade all the drivers, but no luck. Is Fujitsu going to fix it somehow please?
