There is nothing wrong with the GS, if what I think is correct.

Your Extended Keyboard II is damaged.  Specifically, the keyswitch
of the "s" character is stuck.  The solution is to try to lubricate
the keyswitch.  If that does not work, you will have to replace
it.  This is not difficult, I've done it myself.  Just remove the
all the keycaps, unscrew the bottom of the case from the top, and
disassemble the keyboard.  Then locate the faulty keyswitch, desolder
it, and solder in a new one (or swap keyswitches with an unused or
non-important key . . . an extended keyboard tends to have a few of
these).

If you are going to try to lubricate the keyswitch, make sure to
use non-conductive lubricant!
