I formatted my Sony Vaio Vpc F13wfx/bc, and all components has working correctly, except for the keyboard backlight.

The problem is that the keyboard light never turns off.

enter image description here

I tried to install this it: Sony® Notebook Utilities but neither worked.

I installed the windows 7 ultimate 64bits

Anyone ever had this problem? know of any driver that works, or how I permanently turn off the lights?

Thanks

Have you tried to setting up the turn off time in the BIOS? –  Sebastián Sep 21 '12 at 13:55
    
I'm working and do not have it here, but as I recall has no such setting in BIOS. She has few settings. When I get home, I'll search this setting –  Xosler Sep 21 '12 at 14:02

If you know where this setting is in the BIOS, please describe how to get there, et cetera. Cheers! –  slhck Sep 22 '12 at 13:34

Try this:

sudo "echo 1 > /sys/class/leds/keyboard/brightness"

After a Long time search, i found this solution

echo 0 > /sys/devices/platform/sony-laptop/kbd_backlight

It's working very well.

I'm using Fedora 18 :)
