I got my Satellit 800 back from R.L. Drake today with a brand new encoder.
But now, for some reason, I can't get the damn thing to run off the
batteries. They are in there correctly (I know I killed a lot of brain
cells in college, but still...) I had no problems with the batteries before
I sent it off. Could Drake have screwed up something related to the battery
power supply while fixing the encoder? Also, the "." key is sticking a
little bit too, which I also don't remember happening before I sent it off.
Does replacement of the encoder require some work with the keypad?

Any comments/suggestions would be appreciated. Thanks.
