I had to format and re-install Windows XP on a Satellite A105-S4201 Laptop. I installed XP, and updated to SP3. The brightness control no longer works using Fn+F6/F7 (or any other way for that matter). It was working before the format. I tried a couple of different Common Modules installs. This one: tc00324000b (version 6.07.03) won't even install. Gave me error message, "TVALG Driver installation has failed". And this one: SPA210 TCommon Modules-XP (version 1.00.06) installed, and had me restart, but when I tried to install the hotkey utilities afterward, it said "TOSHIBA Common Module not found! This setup will terminate." Also, I have the latest BIOS version installed (v 6.0) Any ideas?
