Calculator how to deal with poor contact of the circuit board

If the keys don't respond, you should also check the battery status of the calculator. When the battery level decreases, the calculator's reaction time slows down or becomes unresponsive. Therefore, replacing the battery is also a good way to solve the problem.

Repair or replace circuit boards

If cleaning the keys and replacing the battery can't fix the calculator, you may need to send the calculator to the product manufacturer for repair or a replacement circuit board. After identifying the problem with the calculator, the manufacturer inspects and repairs the calculator with the correct tools and replacements, and ensures that the board connectors are reconnected.
