• Question 45:

  You are preparing to service a MacBook. To reduce the risk of damage from ESD, you clear the area of plastic, vinyl, or foamed polystyrene, and have static-shielding storage bags available for ESD- sensitive components. While you are working you should also remember to ________________ and _______________. SELECT TWO

  A. ground yourself and the equipment you are working on
  B. always place ESD-sensitive components on metal surfaces
  C. discharge the display to protect the other ESD-sensitive components
  D. handle any ESD-sensitive components by the connectors, rather than by the edges
  E. ask other technicians to avoid touching you when you are working on ESD-sensitive components
  A. ground yourself and the equipment you are working on
  E. ask other technicians to avoid touching you when you are working on ESD-sensitive components

  ---

  Before working on any circuit board or assembly containing ESD-sensitive circuits, groundyourself and the equipment you are working on to an earth or building ground. Use agrounded conductive workbench mat and a grounding wrist strap, and ground the equipmentto the mat. Do not touch anyone who is working on ESD-sensitive circuits or circuit boards of any kind. Ifyou touch someone who is properly grounded, your "zap" or body charge may not cause anydamage, but just to be safe, keep your own body charge away from other technicians.

  When Do You Use a Multimeter?

  Verifying Backup Battery VoltageVolts DC

  You can measure a computer's backup or main battery DC voltage to determine if the battery is dead andrequires replacement. An example of this procedure is outlined above. Other examples of this procedure canbe found in many Apple

  service manuals.

  Verifying Power Supply Output VoltageVolts DC

  You can also measure the DC voltage outputs from a computer's power supply to determine if the powersupply is faulty and requires replacement. Examples of this procedure can be found in the Power Mac G5 (Late2005) Power Supply

  Verification procedure.

  Verifying AC Input VoltageVolts AC

  You can measure AC input voltage into a computer's power supply to determine if the computer's power supplyor AC line filter / AC power input is faulty. Examples of this procedure can be found in the iMac (Flat Panel)service manual, in the

  'No Power' troubleshooting symptom charts. Another example can be found in the eMacATI Graphics/USB 2.0/2005 no power troubleshooting section. The image below was taken from the eMac ATIGraphics/USB 2.0/2005 service manual.
