-- Posted by Majo at 1:03 pm on Aug. 3, 2008 My FN key won't work so I can't adjust how bright my screen is. How can I do it without using it?

Would doing so fix that key or what? Because several keys aren't working... underscore six print screen delete home And maybe a few others that I haven't used yet. -- Posted by blufindr at 1:30 am on Aug. 6, 2008 I think that just means your keyboard died. Send it back to Sony.
