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

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

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

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

• 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‐
