T61 FN Key worked sporadically, then stopped working completely - Anyone know a cure?

Question

Hi,
I'm running a T61 (8892-02U), with XP SP3.  All's been stable for about a year. 
Within the last month my FN (Function) key became more and more sporadic.  I typically only used it in conjunction with the PgUp key to control the keyboard light, and Home/End for screen brightness and F7 for entering projector mode. 
Sometimes when I held it down, pressing the the second key would produce the correct response, other times it wouldn't.  Finally it stopped working entirely. 
I haven't modified the program set or turned off features (that I know of). 
I can initiate presentation director by running the executable.  I really miss the ability to dim the screen.
Anyone else having the same problem?  Have I inadvertently turned it off somehow?  I thought it was hardwired. 
Is there any way I can test if the key contacts are still good (besides using it in conjunction with the aforementioned keys)?
Does anyone have a cure?
Thanks!

mressl, welcome to the forum,
Fn + PgUp, (diagonally opposite from each other), should turn on and off the ThinkLight at the top of the screen. (PgDn does nothing and is irrelevant). This should work as soon as the system is started, it does on my T43 before entering my power on password.
Please excuse a potentially stupid question, but have you had a look under the key? I once had a case where I got the "merry runaround" because a particular key didn't work, the cure was to remove the half a peanut that had found it's way underneath it.
