Hi Paul:

If your Toshiba is anything like my Tecra 510,
there are some strange conditions you can get
into with that "FN" key.  I'm careful not to
press it.  Whenever I get stuck in one of those
weird modes, I have to look in the manual to
get myself back to normal, because the Toshiba
"remembers" the setting from one day to the
next.

First, make sure you aren't in "Resume" mode,
which never lets the computer do a full shutdown
and reboot.  Mine toggles with FN+F3, and there's
no tally light to tell you whether it's on or off.
The only way I know to check is to go into "real" 
DOS and turn the computer power switch off.  
When I next turn the power switch back on, if it
comes right back to the DOS prompt without going
through "POST", you're stuck in "Resume" mode.
Get out of it.

FN+F10 and FN+F11 do some things to NUMLOCK and
the arrow keys, but there are tally lights that
stay lit when these features are engaged.

FN+F12 controls SCROLL LOCK, has no tally, and
I don't know what SCROLL LOCK does when it's
engaged.  Sorry.

There's also an "FN" setting in the BIOS.  I keep
mine set on "Disabled."

I've also wrecked one internal keyboard once
using an external keyboard in the PS-2 port.
But nobody ever was able to explain why that
should wreck the internal keyboard, but it sure
did, so I don't use external keyboards anymore.

Good luck.

Jerry
