Examine & Test
  • Examine the contact pads for corrosion.

  • To test if the corrosion is causing the calculator to not power on:

  • Place good batteries in the back of the case (proper direction)

  • Lay the circuit board over the batteries (4 little posts will align them)

  • Press down a little over the batteries to make sure they have a good connection (if necessary)

  • Tap a screwdriver to short the "ON" contact pad (top right)

  • If the display comes on, then the corrosion is the problem

  • Follow the same steps for testing if the corrosion is causing a key not to work. Except short the contact pad for that key to test it.
