I'm bringing up this post because I've tried the solution to the LED issue offered here. However, I've checked the BIOS configuration and can't find the option to disable the LED once the driver was installed.
-My notebook is an Envy 4.
-The driver version installed was 21, which I thought would be better than v13 suggested in the thread back then.
The issue covered in that post is not the same as mine, but many thanks, mdklassen. It's not the whole keyboard, it's not even malfunctioning, my keyboard. My model of notebook has backlight always on under the F5 key, and it's annoying to me. I just happened to find a thread where they say how to disable it on an Xperia model, and I' like to do the same on mine.
