1. Safetyprecautions
1.1. General guidelines
1. Whenservicing, observetheoriginal leaddress. Ifashortcircuit
isfound, replace all parts whichhavebeenoverheatedor
damagedbytheshortcircuit.
2. Afterservicing, see toitthat all theprotectivedevices suchas
insulation barriers, insulation papersshieldsareproperlyinstalled.
3. Afterservicing, make thefollowing leakagecurrentchecks to
preventthecustomerfrombeing exposedtoshock hazards.
1.1.1. Leakagecurrentcoldcheck
1. Unplug theACcordand connect ajumperbetweenthetwoprongs
on theplug.
2. Measuretheresistance value, withanohmmeter, betweenthe
jumperedACplug and eachexposedmetalliccabinet parton the
equipmentsuchas screwheads, connectors, control shafts, etc.
Whentheexposedmetallicparthas areturnpathtothechassis,
thereading shouldbebetween1M and 5.2M . / Whenthe
exposedmetal does nothaveareturnpathtothechassis, the
reading must be . Figure1
1.1.2. Leakagecurrenthotcheck / (See Figure 1 .)
2

1. Plug theACcorddirectlyintotheACoutlet. Donotuse an
isolation transformerforthischeck.
2. Connect a1.5k , 10 watts resistor, inparallel witha0.15 F
capacitors, betweeneachexposedmetallicparton theset and a
good earthground suchas awaterpipe, as shownin Figure1.
3. Use anACvoltmeter, with1000 ohms/voltormoresensitivity, to
measurethepotential across theresistor.
4. Check eachexposedmetallicpart, and measurethevoltageat
eachpoint.
5. Reverse theACplug intheACoutlet and repeat eachoftheabove
measurements.
6. Thepotential at anypointshouldnotexceed0.75 volts RMS. A
leakagecurrenttester(Simpson Model 229 orequivalent) maybe
usedtomake thehotchecks, leakagecurrentmust notexceed1/2
milliampere. Incase ameasurementisoutsideofthelimits
specified, thereisapossibilityofashock hazard, and the
equipmentshouldberepairedand recheckedbeforeitisreturned
tothecustomer.
1.2. Caution forfuse replacement
2. Prevention of ElectrostaticDischarge (ESD) to
ElectrostaticSensitive(ES) Devices
Somesemiconductor (solidstate)devices canbedamagedeasilybystaticelectricity. Such
componentscommonlyarecalledElectrostaticSensitive (ES)Devices. Examples oftypical ES
devices areintegratedcircuitsand somefield-effecttransistor-sandsemiconductor "chip"
components. Thefollowing techniques shouldbeusedtohelpreduce theincidence of
componentdamagecausedbyelectrostaticdischarge(ESD).
1. Immediatelybeforehandling anysemiconductorcomponentor
semiconductor-equippedassembly, drainoff anyESDon your
bodybytouching aknownearthground. Alternatively, obtainand
wearacommerciallyavailabledischarging ESDwrist strap,
3

whichshouldberemovedforpotential shock reasonspriorto
applying powertotheunitundertest.
2. Afterremoving anelectrical assemblyequippedwithES devices,
place theassemblyon aconductivesurface suchas aluminum
foil, topreventelectrostaticchargebuildup orexposureofthe
assembly.
3. Use onlyagrounded-tipsoldering iron tosolderorunsolderES
devices.
4. Use onlyananti-staticsolderremoval device. Somesolder
removal devices notclassifiedas "anti-static(ESDprotected)"can
generate electrical chargesufficienttodamageES devices.
5. Donotuse freon-propelledchemicals. These cangenerate
electrical charges sufficienttodamageES devices.
6. DonotremoveareplacementES device fromits protective
packageuntil immediatelybeforeyou arereadytoinstall it. (Most
replacementES devices arepackagedwithleadselectrically
shortedtogetherbyconductivefoam, aluminumfoil or
comparableconductivematerial).
7. Immediatelybeforeremoving theprotectivematerial fromthe
leadsofareplacementES device, touchtheprotectivematerial to
thechassisorcircuitassemblyintowhichthedevice will be
installed.
Caution
Besureno powerisappliedtothechassisorcircuit, and observe
all othersafetyprecautions.
8. Minimizebodilymotionswhenhandling unpackagedreplacement
ES devices. (Otherwise hamless motion suchas thebrushing
togetherofyourclothes fabricorthelifting ofyourfootfroma
carpetedfloorcangenerate staticelectricitysufficienttodamage
anES device).

4. Howtoreplace the LithiumBattery
REPLACEMENTPROCEDURE
1. RemovetheTop case and DVD-RAMdriveunitwithMainP.C.B. by
referring theDisassembling Procedure.
2. UnsoldertheLithiumBatteries:B7501 and thenreplace itintonew

5. Handling the Lead-free Solder
5.1. Aboutleadfree solder(PbF)
Distinction ofPbF P.C.B.:
P.C.B.s(manufactured)using leadfree solderwill have aPbF stampon theP.C.B.
Caution:
-Pbfree solderhas ahighermelting pointthanstandardsolder;
Typicallythemelting pointis50 -70°F(30 -40°C)higher. Please
use ahigh temperaturesoldering iron. Incase ofthesoldering iron
withtemperaturecontrol,please set itto700 ±20°F(370 ±10°C).
-Pbfree solderwill tend tosplashwhenheatedtoo high (about
1100°F/600°C).
-Whensoldering orunsoldering, please completelyremoveall ofthe
solderon thepinsorsolderarea, and besuretoheat thesoldering
points withthePbfree solderuntil itmelts enough.
