Hello.
I use my Dell Inspiron 1525 with a brazilian keyboard layout, and some keys accessible only thru the "Fn" key don't work, like the SysRq, Pause and Scroll Lk keys. Yet, the numerical keypad works. I'm currently using as a keyboard model the "Dell Laptop/notebook inspiron 6xxx/8xxx" option, in the lack of a better one.
How can I make these keys work? I noticed this when I tried to use the "magic SysRq" key commands.
