My Lenovo W500, 4 years old, has a bug making brightness up/down not working with most drivers. The only driver that has ever worked for me is ATI version 8.641.1.1000 (Windows 7, 64).
I have reinstalled Windows, and now I need this good old driver!
I have tried more than 15 newer ones, but they dont solve the brightness bug.
I have found many websites ssaying I can download 8.641.1.1000, but they always test my system and force me to use something newer, that doesn't work.
Please, were can i find ATI 8.641.1.1000???
