Doing It Right

Tools and Consequences

Experienced technicians can easily spot a bad repair when they see: stripped screws missing screws bent pins broken connectors improperly bent cables

Many of these problems occur because someone was in a hurry and "made do" with the tools that were immediately available.

Doing It Right

Follow these steps:

Review Service Manual documentation before attempting a new procedure

Identify and have on hand the correct tools called out in the Service Manual

Avoid "making do" with incorrect tools

Keep careful track of screws and other small parts to avoid using the wrong screw in the wrong place

If a procedure involves removing multiple parts (replacing a Mac Pro logic board is a good example) make sure that you have sufficient static bags for storage and some means of keeping track of the screws or other small parts you remove

ESD Related Tools

The following tools are needed to create an ESD-compliant work area:

ESD Wriststrap with clip/plug

Grounded ESD Mat

Wire Lead with Alligator Clips

Ground/Polarity Tester – A polarity tester allows you to make sure that any grounded plugs you use are correctly wired.

ESD storage bags to hold components

ESD equipment is described in detail in the ESD course.

This tool allows you to magnetize your screwdrivers and other tools. It also allows you to demagnetize them in situations where a magnetized tool may harm components.

Magnetizer

Needlenose Pliers

Utility Knife or

Razor Blade

ESD - Compliant

Plastic Probe

Metric Ruler

Fine-point felt-tip permanent marker

Tweezers

Paper Clip

Coin

You may want to have both small and large pliers. Any pliers you get will need to have small tips.

In some situations, you may need to detach tape or cut plastic components.

This gives you a more precise means of moving components and cables. A good example of this is Apple's Nylon Probe

Tool (black stick). Another name for this type of tool is

"spudger".

Screws in portable Mac computers are referred to by their lengths in millimeters, and many are very small, requiring you to verify their lengths to ensure you are replacing the right screw. Also, having a straight edge can be useful in many situations.

You may be required to mark the locations of various internal components, such as thermal sensors, to ensure they are replaced in exactly the same positions.

Plastic tweezers are preferable since they are less likely to damage components. Be sure that they are ESD - compliant.

There are some situations such as forcing open an optical drive tray or resetting an AirPort Base Station where only a paper clip will work.

Some portable computer models require a coin to unlock and remove the battery.

Multimeter

ESD - Compliant

Screw Box

Glue Gun/Glue

Sticks

In some situations, you will need to measure voltage and resistance. Details of multimeter use are provided later in this course.

Given the many screws in each Mac, you need a partitioned screw box with at least 12 partitioned sections.

Some repairs may require that you glue down a component.

Cup Hook

1600 Watt Hair

Dryer

Flashlight

Dental Pick

One Power Mac computer has a plastic rivet that can only be removed via screwing in a cup hook and leveraging the hook with a screwdriver or wooden chopstick.

One portable Mac computer requires the hair dryer to heat component adhesive prior to component removal. Do not use a heat gun because it can be far too hot.

As computers use ever smaller components, getting enough light on where you are working is getting increasingly difficult. Also, some portable Mac computers require flashlights as part of troubleshooting video issues.

A very sharp probe is sometimes useful when you need to move components small distances. Moving cables while checking routing is one example.

Alcohol Wipes and

Pads

Small Brush

Some procedures require that thermal paste be cleaned off a component. These are the best tools for doing this.

This is useful for cleaning debris from MagSafe connectors.

Small Wire Cutter

In some situations, you may need to cut cabling.

Double Stick Tape

This is used to reattach components such as thermal sensors.

Known-Good

CD or DVD

Dental Mirror

To test optical drives, you need to have a working CD or

DVD. You may also want to have some blank discs on-hand to use in case the optical drive may damage discs.

This is useful for looking under or behind components.

Safety Tips when Using a Multimeter

Overview

You may need to verify a computer's power supply voltages when troubleshooting power issues, or check the resistance of cables when troubleshooting intermittent connection issues. Taking multimeter measurements as part of a troubleshooting procedure can quickly isolate the cause of an issue.

Before taking a measurement the multimeter must be configured to read the desired parameter and set to the correct range. Refer to Service Source service manual troubleshooting documentation to determine what parameters are being measured as part of the troubleshooting flow, and then configure the multimeter appropriately.

NOTE: High voltages in energized circuits can kill - use caution when using a multimeter.

What Is a Multimeter?

A multimeter is an instrument for measuring several different electrical parameters including most commonly voltage, current, and resistance.

Multimeter Design

Measurement Symbol Units

DC Voltage Volts DC

DC Current Amps DC

AC Voltage Volts AC

Resistance Ohms

A typical modern digital multimeter (also known as a DMM) has an LCD or LED digital numeric readout and various switches and/or dials to configure the multimeter to measure one of the available parameters, such as DC voltage, AC voltage, DC current, AC current, resistance, etc. You will see symbols on the multimeter like the ones shown above which represent these measurement parameters and units.

A multimeter also has two or three electrical terminals built into its enclosure, into which are usually inserted

two short colored-wire leads (usually one red or 'positive', one black or 'negative'), the ends of which terminate in stiff, pointed ends called 'probes'.

The colors of the probes identify the polarity (+ positive or - negative) of DC voltage and DC current parameters during measurement (AC voltage, AC current and resistance have no polarity). The tips of the probes are brought into electrical contact with the part of the circuit being measured by the user, and thus carry the voltage to be measured to the multimeter's internal circuitry where the magnitude of the appropriate parameter is determined and displayed (e.g. +12.0 DC Volts).

When measuring AC or DC voltages or resistance the black probe is connected to the terminal labeled common (COM) and the red probe is connected to the terminal that is usually labeled with the symbols for voltage and resistance. Some multimeters may provide additional capabilities such as temperature and diode measurements that are also made using this terminal. When measuring current the red probe must be moved to the terminal labeled with an A, mA, or µA indicating amperage. Only use the current terminal for current measurements and nothing else.

NOTE: The safe use of a multimeter requires an understanding of the voltages used in the circuits being measured. Multimeters are always designed with an upper limit on the magnitude of parameters such as voltage and current that they can safely measure. This limit is usually somewhere in the range of a few hundred Volts, DC or AC, and a few Amperes, DC or AC. Specialized equipment is required to safely measure any voltages or currents above this range, which is beyond what would be expected inside a typical computer anyway. It is unsafe to measure CRT voltages using a multimeter without specialized equipment.

How to Use a Multimeter

The technician turns the multimeter on by its switch, and then selects the appropriate dial or switch positions to configure the multimeter to read the desired electrical parameter, such as DC voltage

The technician energizes the circuit being measured, then, holding the two probes, one in each hand, the technician carefully touches the pointed ends of the two probes to the part of the circuit being measured, to make electrical contact, being careful not to touch the probes to anything else or to each other.

The multimeter will then display the magnitude and polarity of the parameter on its display as long as the probes are making contact with the circuit under test.

For example, to measure the voltage of the backup battery in a desktop Mac (which is typically located somewhere on the main logic board):

1. Locate the battery on the logic board and identify its type, so you know what its expected voltage capacity should be. Most recent desktop Mac backup batteries should be 3.6 DC Volt capacity.

2. Identify the battery's positive and negative terminals (they are usually marked as + and - on the logic board, somewhere near the battery).

3. Turn on and configure the multimeter for DC voltage. Ensure the multimeter's display reads 0.0 DC

Volts when not measuring anything.

4. Carefully touch the black (- negative) multimeter probe to the - negative battery terminal, and the red

(+ positive) multimeter probe to the + positive battery terminal, being careful not to touch the probes to

anything else or to each other.

5. Observe the multimeter's display. Most recent desktop Mac backup batteries should read somewhere around +3.6 DC Volts. A dead Mac backup battery would typically read somewhere between 0.0 DC

Volts and +0.5 DC Volts. By the way, even though the multimeter's leads are polarized, they can be safely connected to the battery backwards without harm; this would simply cause the multimeter's display to read -3.6 DC Volts instead of +3.6 DC Volts.

When Do You Use a Multimeter?

Verifying Backup Battery Voltage Volts DC

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

Verifying Power Supply Output Voltage Volts DC

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

(Late 2005) Power Supply Verification procedure.

Verifying AC Input Voltage Volts AC

You can measure AC input voltage into a computer's power supply to determine if the computer's power supply or 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 eMac ATI Graphics/USB 2.0/2005 no power troubleshooting section. The image below was taken from the eMac ATI Graphics/USB 2.0/2005 service manual.

CAUTION: Measuring AC input voltage (sometimes called mains or line voltage) can be very dangerous and is only advised for skilled technicians with multimeter measurement experience. This voltage is typically in the 120-240 AC Volt range, which can cause lethal electrocution. Use extreme care whenever measuring any voltages of this magnitude.

Verifying Cable Connectivity Ohms

You can measure electrical resistance in a cable, to determine if the cable is faulty or to measure a fuse to determine if it has blown or is intact. In this case, the multimeter is set to measure resistance in Ohms, and the cable or fuse to be tested is completely removed from its circuit.

The two multimeter probes are then simultaneously touched one to each end of the cable or fuse. The expected reading for a good cable or fuse that is making good connection is somewhere close to 0 Ohms

(which represents no resistance or a closed circuit). A bad connection caused by a faulty cable or blown fuse would read infinite Ohms (which represents infinite resistance or an open circuit).

CAUTION: When measuring resistance, the multimeter must be connected only to circuits or cables which have been de-energized (that is, all sources of electrical power to the circuit have been removed by disconnection).

This is because a multimeter measuring resistance actually sources a small amount of constant electrical current coming out of its probes which flows through the probes into the cable or circuit being measured, and this allows the multimeter to measure this electrical flow and calculate the resistance from the voltage drop measured between its two probes.

Attempting to measure resistance in an energized circuit will not only cause inaccurate readings, it can also be dangerous and may damage either the circuit under test, the multimeter, or both. Resistance measurements are therefore usually only made on things like disconnected cables and connectors, to verify a good or bad electrical connection.

Verifying Circuit Current Flow Amps DC

You can also use a multimeter on DC current settings to measure the amount of electrical current flowing through a circuit, such as when verifying the charging circuitry in an Apple portable product by measuring the amount of DC current flowing through a connected AC power adapter. This is rarely done during most troubleshooting scenarios, because it involves connecting the multimeter 'in series' with the circuit being tested, which is an invasive procedure.

'In series' means that the multimeter is actively connected into the circuit such that the circuit's current also flows directly through the meter, and this usually requires 'breaking into' the circuit being tested using special patch cables and connectors, rather than simply touching the multimeter probe tips to the circuit. There is also a special third probe jack on most multimeters that is used only for current measurements. Readings are in units of Amps (Amperes) or milliamps (thousandths of an Amp).

Caution: Extreme care should be taken when making current measurements as it is very easy to short the circuit out and damage it by incorrectly connecting the probes.

Safety Tips when Using a Multimeter

Here is a summary of some important safety tips when using a multimeter to measure electrical circuits.

Please consult the operator's guide for the multimeter being used for specific instructions and tips:

Be sure the test leads and multimeter switch(es) are in the correct position for the desired measurement.

Never use the multimeter if the meter or the test leads look damaged.

Never measure resistance in a circuit when power is applied.

Never touch the probes to a voltage source when a test lead is plugged into the 10 A or 300 mA current input jack.

To avoid damage or injury, never use the multimeter on circuits that exceed the maximum ratings

specified for that meter.

Never apply more than the rated voltage between any input jack and earth ground.

Be careful when working with voltages above 60 V DC or 30 V AC. Such voltages pose a shock hazard.

Keep your fingers behind the finger guards on the test probes when making measurements.

To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery inside the multimeter as soon as the battery indicator appears.
