• Ifyouneedtoworkonamachinethathasexposedelectricalcircuits,observe

thefollowingprecautions:

– Ensurethatanotherperson,familiarwiththepower‐offcontrols,isnear

you.

Attention:Anotherpersonmustbetheretoswitchoffthepower,if

necessary.

– Useonlyonehandwhenworkingwithpowered‐onelectricalequipment;

keeptheotherhandinyourpocketorbehindyourback.

Thepurposeofthisinspectionguideistoassistyouinidentifyingpotential

unsafeconditions.Aseachmachinewasdesignedandbuilt,requiredsafety

itemswereinstalledtoprotectusersandservicepersonnelfrominjury.This

Ifanyunsafeconditionsarepresent,youmustdeterminehowseriousthe

apparenthazardcouldbeandwhetheryoucancontinuewithoutfirstcorrecting

theproblem.

Considertheseconditionsandthesafetyhazardstheypresent:

• Electricalhazards,especiallyprimarypower(primaryvoltageontheframe

• Explosivehazards,suchasadamagedCRTfaceorabulgingcapacitor

• Mechanicalhazards,suchaslooseormissinghardware

Todeterminewhetherthereareanypotentialunsafeconditions,usethe

followingchecklistatthebeginningofeveryservicetask.Beginthecheckswith

thepoweroff,andthepowercorddisconnected.

Checklist:

1. Checkexteriorcoversfordamage(loose,broken,orsharpedges).

2. Turnoffthecomputer.Disconnectthepowercord.

3. Checkthepowercordfor:

a. Athird‐wiregroundconnectoringoodcondition.Useametertomeasure

third‐wiregroundcontinuityfor0.1ohmorlessbetweentheexternal

groundpinandtheframeground.

b. Thepowercordshouldbethetypespecifiedinthepartslist.

c. Insulationmustnotbefrayedorworn.

4. Checkforcrackedorbulgingbatteries.

5. Removethecover.

6. Checkforanyobviousnon‐Lenovoalterations.Usegoodjudgmentastothe

safetyofanynon‐Lenovoalterations.

7. Checkinsidetheunitforanyobviousunsafeconditions,suchasmetalfilings,

contamination,waterorotherliquids,orsignsoffireorsmokedamage.

8. Checkforworn,frayed,orpinchedcables.

9. Checkthatthepower‐supplycoverfasteners(screwsorrivets)havenotbeen

Safety inspection guide

Safety information

Anycomputerpartcontainingtransistorsorintegratedcircuits(ICs)shouldbe

consideredsensitivetoelectrostaticdischarge(ESD).ESDdamagecanoccur

whenthereisadifferenceinchargebetweenobjects.ProtectagainstESDdamage

byequalizingthechargesothatthemachine,thepart,theworkmat,andthe

personhandlingthepartareallatthesamecharge.

WhenhandlingESD‐sensitiveparts:

• Keepthepartsinprotectivepackagesuntiltheyareinsertedintotheproduct.

• Avoidcontactwithotherpeople.

• Wearagroundedwriststrapagainstyourskintoeliminatestaticonyour

body.

• Preventthepartfromtouchingyourclothing. Mostclothingisinsulativeand

retainsachargeevenwhenyouarewearingawriststrap.

• Usetheblacksideofagroundedworkmattoprovideastatic‐freework

surface.ThematisespeciallyusefulwhenhandlingESD‐sensitivedevices.

• Selectagroundingsystem,suchasthoselistedbelow,toprovideprotection

thatmeetsthespecificservicerequirement.

– AttachtheESDgroundcliptoanyframeground,groundbraid,orgreen‐

wireground.

– Whenworkingonadouble‐insulatedorbattery‐operatedsystem,usean

ESDcommongroundorreferencepoint.Youcanusecoaxorconnector‐

outsideshellsonthesesystems.

– Usetheroundgroundprongoftheacplugonac‐operatedcomputers.
