OK sorry maybe your L notebook doesn’t have this option in BIOS. Many other models have it definitely.
Problem is as follow:
Windows 7 64 bit is supported but you didn’t got it with your notebook and I don’t know how you have installed it. Fact is that all necessary drivers and Toshiba specific tools and utilities must be installed in right installation order.
I will send you install order for Vista. Generally speaking, the principle for Win7 installation should be the same.
LAN Driver Version
Touch Pad Driver
Wireless LAN Driver
TOSHIBA Value Added Package
TOSHIBA Hardware Setup Utility
TOSHIBA Supervisor Password
TOSHIBA Face Recognition
I hope this will help you.
You know there is no some trick. Toshiba value added package contains several tools and utilities and one of them is button support utility. By default it should work after VAP installation.
Generally speaking the illumination buttons are controlled by Value Added Package so theoretically that’s the only tool that you need for these buttons. After installation it must work.
What version of VAP have you installed?
I would also recommend loading the default settings in BIOS and try a BIOS update if the above one didn’t do the trick.
