© C pyright Len v 2022

Important:
• Use nly appr ved t ls and test equipment. S me hand t ls have handles c vered with a s ft material
that d es n t insulate y u when w rking with live electrical currents.
• Many cust mers have, near their equipment, rubber fl r mats that c ntain small c nductive fibers t
decrease electr static discharges (ESD). D n t use this type f mat t pr tect y urself fr m electrical
sh ck.
• Find the r m emergency p wer- ff (EPO) switch, disc nnecting switch, r electrical utlet. If an electrical
accident ccurs, y u can then perate the switch r unplug the p wer c rd quickly.
• D n t w rk al ne under hazard us c nditi ns r near equipment that has hazard us v ltages.
• Disc nnect all p wer bef re:
– Perf rming a mechanical inspecti n
– W rking near p wer supplies
– Rem ving r installing main units
• Bef re y u start t w rk n the machine, unplug the p wer c rd. If y u cann t unplug it, ask the cust mer
t p wer ff the wall b x that supplies p wer t the machine, and t l ck the wall b x in the ff p siti n.
• If y u need t w rk n a machine that has exp sed electrical circuits, bserve the f ll wing precauti ns:
– Ensure that an ther pers n, familiar with the p wer- ff c ntr ls, is near y u. That pers n must be there
t switch ff the p wer, if necessary.
– Use nly ne hand when w rking with p wered- n electrical equipment; keep the ther hand in y ur
p cket r behind y ur back.
CAUTION:
An electrical shock can occur only when there is a complete circuit. By observing the above rule,
you may prevent a current from passing through your body.
– When using testers, set the c ntr ls c rrectly and use the appr ved pr be leads and access ries f r
that tester.
– Stand n suitable rubber mats ( btained l cally, if necessary) t insulate y u fr m gr unds such as
metal fl r strips and machine frames.
Observe the special safety precauti ns when y u w rk with very high v ltages. Instructi ns f r these
precauti ns are in the safety secti ns f maintenance inf rmati n. Use extreme care when measuring high
v ltages.
• Regularly inspect and maintain y ur electrical hand t ls f r safe perati nal c nditi n.
• D n t use w rn r br ken t ls and testers.
• Never assume that p wer has been disc nnected fr m a circuit. First, check that it has been p wered ff.
• Always l k carefully f r p ssible hazards in y ur w rk area. Examples f these hazards are m ist fl rs,
n ngr unded p wer extensi n cables, p wer surges, and missing safety gr unds.
• D n t t uch live electrical circuits with the reflective surface f a plastic dental mirr r. The surface is
c nductive; such t uching can cause pers nal injury and machine damage.
• D n t service the f ll wing parts with the p wer n:
– P wer supply units
– Fans
– Units similar t th se listed ab ve
This practice ensures c rrect gr unding f the units.
• If an electrical accident ccurs:
– Use cauti n; d n t bec me a victim y urself.
– Switch ff p wer.
– Send an ther pers n t get medical aid.
2P16 Gen 1 Hardware Maintenance Manual

Safety inspection guide
The purp se f this inspecti n guide is t assist y u in identifying p tentially unsafe c nditi ns. As each
machine was designed and built, required safety items were installed t pr tect users and service
technicians fr m injury. This guide addresses nly th se items. Y u sh uld use g d judgment t identify
p tential safety hazards due t attachment f n n-ThinkPad / n n-Len v features r pti ns n t c vered by
this inspecti n guide.
If any unsafe c nditi ns are present, y u must determine h w seri us the apparent hazard c uld be and
whether y u can c ntinue with ut first c rrecting the pr blem.
C nsider these c nditi ns and the safety hazards they present:
• Electrical hazards, especially primary p wer (primary v ltage n the frame can cause seri us r fatal
electrical sh ck)
• Expl sive hazards, such as a damaged CRT face r a bulging capacit r
• Mechanical hazards, such as l se r missing hardware
T determine whether there are any p tentially unsafe c nditi ns, use the f ll wing checklist at the
beginning f every service task. Begin the checks with the p wer ff, and the p wer c rd disc nnected.
Checklist:
1. Check exteri r c vers f r damage (l se, br ken, r sharp edges).
2. Turn ff the c mputer. Disc nnect the p wer c rd.
3. Check the p wer c rd f r:
a. A third-wire gr und c nnect r in g d c nditi n. Use a meter t measure third-wire gr und
c ntinuity f r 0.1 hm r less between the external gr und pin and the frame gr und.
b. The p wer c rd sh uld be the auth rized type specified f r y ur c mputer. G t : https://
supp rt.len v .c m/partsl kup.
c. Insulati n must n t be frayed r w rn.
4. Check f r cracked r bulging batteries.
5. Rem ve the c ver.
6. Check f r any bvi us n n-ThinkPad / n n-Len v alterati ns. Use g d judgment as t the safety f
any n n-ThinkPad / n n-Len v alterati ns.
7. Check inside the unit f r any bvi us unsafe c nditi ns, such as metal filings, c ntaminati n, water r
ther liquids, r signs f fire r sm ke damage.
8. Check f r w rn, frayed, r pinched cables.
9. Check that the p wer-supply c ver fasteners (screws r rivets) have n t been rem ved r tampered
with.
Handling devices that are sensitive to electrostatic discharge
Any c mputer part c ntaining transist rs r integrated circuits (ICs) sh uld be c nsidered sensitive t
electr static discharge (ESD). ESD damage can ccur when there is a difference in charge between bjects.
Pr tect against ESD damage by equalizing the charge s that the machine, the part, the w rk mat, and the
pers n handling the part are all at the same charge.
Notes:
1. Use pr duct-specific ESD pr cedures when they exceed the requirements n ted here.
Chapter 1.Safety inf rmati n 3

2. Ensure that the ESD pr tective devices y u use have been certified (ISO 9000) as fully effective.
When handling ESD-sensitive parts:
• Keep the parts in pr tective packages until they are inserted int the pr duct.
• Av id c ntact with ther pe ple.
• Wear a gr unded wrist strap against y ur skin t eliminate static n y ur b dy.
• Prevent the part fr m t uching y ur cl thing. M st cl thing is insulative and retains a charge even when
y u are wearing a wrist strap.
• Use a gr unded w rk mat t pr vide a static-free w rk surface. The mat is especially useful when
handling ESD-sensitive devices.
• Select a gr unding system, such as th se listed bel w, t pr vide pr tecti n that meets the specific
service requirement.
Note: The use f a gr unding system t guard against ESD damage is desirable but n t necessary.
– Attach the ESD gr und clip t any frame gr und, gr und braid, r green-wire gr und.
– When w rking n a d uble-insulated r battery- perated system, use an ESD c mm n gr und r
reference p int. Y u can use c ax r c nnect r- utside shells n these systems.
– Use the r und gr und pr ng f the ac plug n ac- perated c mputers.
Grounding requirements
Electrical gr unding f the c mputer is required f r perat r safety and c rrect system functi n. Pr per
gr unding f the electrical utlet can be verified by a certified electrician.
