The so-called electrically neutral bodies are bodies that have the same number of protons and electrons in their structure.
Bodies may have an imbalance in their neutrality due to the difference in the amount of positive and negative charges in their structure and these, when in contact with other bodies (charged with opposite or neutral charges), they cause the orderly movement of electrical charges, generating current electric. The passage of electric current through a certain body (conductor) is what causes the electric shock.
People who have static charge accumulation (accumulation usually caused by the frictional electrification process, usually more expressive on dry days) when in contact with others that are charged by charges of opposite sign or neutral will receive shock due to the movement of electrical charges from one body to another, until both meet neutralized.
When handling computer boards, the buildup of static charges on your hands must be neutralized,
thus preventing the board from being damaged
