that are sensitive to static electricity. Handling and servicing of components that are
sensitive to ESD should be done only by qualified personnel and only after reading and
understanding proper ESD techniques. The following ESD guidelines should be
followed. Following these rules can greatly reduce the possibility of ESD damage to PC
