[Tfug] Battery replacement

[erich]

I took a look at it tonite,
               and the motherboard has one of those batterys with
+/- leads with a connector, and it has a little Velcro patch so it's
relatively easy to replace. The battery is 4.5 volts,(or so it says on
the label.)
          SWS probably has 'em. Maybe even BestBuy.

Most motherboards will allow you to reset to the defaults (and clear out a boot password, etc) by setting a jumper on the motherboard.  But this just reverts back to the default configuration.
