I have a problem: I use system update to install new bios for my laptop ( lenovo t400). But after installing, i have a problem : when i use function key (ex : Fn+ 12, middle point , Fn+F9) , it isn't effective. My Bios version : Lenovo 7UE81WW (3.11) , 11/26/2009. But i don't remember my older version.
Please, help me.
