Hello,
the Fn and up arrow will not brighten my Dell Inspiron 1720 laptop computer. Is has worked before........
 
There should be software to map the function key properly, but the download from Dell's site for the model are very confusing, many just give a generic name for the download with the version number without actually saying what it is.

Unless you want to download random files and install them to see what will fix this, try calling Dell support and asking them what you need.
