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
guideaddressesonlythoseitems.Youshouldusegoodjudgmenttoidentify
potentialsafetyhazardsaccordingtotheattachmentofnon‐Lenovofeaturesor
optionsnotcoveredbythisinspectionguide.
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
cancauseseriousorfatalelectricalshock)
• 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
removedortamperedwith.
