Hi,

I am running an Acer Aspire 5720 with Windows Vista Home Premium (32 bit) and I'm having trouble with the backlight killing button.

fn + F6 is supposed to turn off the backlight until you show some activity but this function only seems to work only once per startup. It'll work the first time and then after that pressing the buttons does nothing until I restart the computer. All the other fn functions work fine so I don't know what's going on.

If anyone has had the same problem or knows a fix it'll be greatly appreciated,
Cheers

PS sorry if this is the wrong place for this thread.

I have the same problem here.
If someone knows the solution, please let we know.
Thank's
