Electrostatic Discharge


aliases:

  • ESD

The discharge of accumulated static electricity from a non-grounded object to a grounded object.

Internal hardware parts are vulnerable to electrostatic discharge (ESD) and can cause the immediate damage or failure of parts, such as the:

  • motherboard
  • processor
  • hard drives
  • memory sticks
  • expansion cards

ESD damage can happen from a discharge as little as 100 volts, while a discharge of upwards of 3,000 volts must happen before you can feel it.

Safety Measures

  • relative humidity in the 35-70% range
  • temperature between 72-77$^\circ$ F
  • use antistatic mats under PCs and on the floor
  • discharge yourself before touching any component
  • always wear an antistatic wrist strap attached to the metal PC chassis
  • keep computer repair locations/stations free of objects and materials that accumulate electric charges, like plastic and Styrofoam
  • NEVER WORK ON INTERNAL COMPONENTS WITH THE SYSTEM STILL PLUGGED IN
