Here is what happens:

  1. I pull out all batteries so the RAM can reset.
  2. Put batteries back in and calculator starts working for about 30 seconds
  3. Calculator shuts off by itself
  4. Turn on, screen flashes real quick to display where I previously was, then shuts off.
  5. #4 repeats until ram is reset again. Things I have tried -OS Reset -RAM Reset -Backup battery and battery replacements -Cleaning connectors I have another calculator I can sub out parts with. Is it a capacitor or something I need to replace?

Try cleaning the I/O port and the USB port of any dust or debris. This can cause it to turn on. Check for a short circuit around the [ON] key. If this doesn’t help, your calculator may have a more serious issue. Such as having a defective component. Try checking any wire and component contacts you can for a broken circuit.
