Electrical Safety

  • disconnect PC from power supply before opening the case
  • Hold the power button for a few seconds after disconnecting the power cord to ensure all the internal components are drained of charge
  • do not disassemble non field repairable components
    • E.g., power supply

Electrostatic Discharge

  • use tools and procedures that minimize risk of damage to electronic components
  • CPU, RAM, adapter cards, motherboard, etc. are all susceptible to ESD
