hapter 3. Tips on using the computer
This chapter pr vides tips n using the c mputer.
Attaching a Kensington-style cable lock
Y u can use a Kensingt n-style cable l ck t secure y ur c mputer t a desk, table, r ther n npermanent
fixture. The cable l ck c nnects t the security-l ck sl t at the rear f y ur c mputer. Depending n the type
selected, the cable l ck can be perated with a key r c mbinati n. The cable l ck als l cks the butt ns
used t pen the c mputer c ver. This is the same type f l ck used with many n teb k c mputers. Y u
can rder such a cable l ck directly fr m Len v by searching f r Kensington at:

hapter 4. Replacing hardware
This chapter pr vides instructi ns n h w t replace hardware f r y ur c mputer.
Before replacing hardware
Attention: D n t pen y ur c mputer r attempt any repairs bef re reading this secti n and the Important
Product Information Guide.
Notes before replacing hardware
• Use c mputer c mp nents pr vided nly by Len v .
• When installing r replacing an pti n, use the appr priate instructi ns explained in this manual al ng with
the instructi ns that c me with the pti n.
• In m st areas f the w rld, Len v requires the return f defective CRUs. Inf rmati n ab ut this will c me
with the CRU r will c me a few days after the CRU arrives.
Handling static-sensitive devices
D n t pen the static-pr tective package c ntaining the new part until the defective part has been rem ved
and y u are ready t install the new part. Static electricity, alth ugh harmless t y u, can seri usly damage
c mputer c mp nents and pti ns.
When y u handle pti ns and ther c mputer c mp nents, take these precauti ns t av id static-electricity
damage:
• Limit y ur m vement. M vement can cause static electricity t build up ar und y u.
• Always handle pti ns and ther c mputer c mp nents carefully. Handle PCI/PCIe cards, mem ry
m dules, system b ards, and micr pr cess rs by the edges. Never t uch any exp sed circuitry.
• Prevent thers fr m t uching the pti ns and ther c mputer c mp nents.
• T uch the static-pr tective package c ntaining the part t a metal expansi n-sl t c ver r ther
unpainted metal surface n the c mputer f r at least tw sec nds. This reduces static electricity fr m the
package and y ur b dy bef re y u install r replace a new part.
• When p ssible, rem ve the new part fr m the static-pr tective package, and install it directly in the
c mputer with ut setting the part d wn. When this is n t p ssible, place the static-pr tective package n
a sm th, level surface and place the part n the package.
• D n t place the part n the c mputer c ver r ther metal surface.
Knowing FRUs (including RUs)
• Field Replaceable Units (FRUs) are c mputer parts that a trained technician can upgrade r replace. FRUs
include all CRUs. F r detailed FRU inf rmati n, such as the FRU part numbers and supp rted c mputer
m dels, g t :
http://www.len v .c m/serviceparts-l kup
• Cust mer Replaceable Units (CRUs) are c mputer parts that a user can upgrade r replace.
– Self-service CRUs: Y u can install self-service CRUs easily. These CRUs might be stand-al ne,
latched, r secured by up t tw screws. Examples f self-service CRUs include the keyb ard, m use,
any USB device. Y u are resp nsible f r replacing all self-service CRUs.
– Opti nal-service CRUs: Handling pti nal-service CRUs requires s me technical skills and simple t ls
(such as a screwdriver). These CRUs are is lated parts within the c mputer. They are usually
© C pyright Len v 2018, 2019 11

c ncealed by an access panel that is secured by m re than tw screws. Y u must rem ve the screws
and panel t access the specific CRU. Opti nal-service CRUs can be rem ved and installed by users
r, during the warranty peri d, by a Len v service technician.
Before replacing FRUs
Bef re replacing any FRU, read the f ll wing:
• Only certified and trained pers nnel can service the c mputer.
• Bef re replacing an FRU, read the entire secti n ab ut replacing the part.
• Be extremely careful during writing perati ns such as c pying, saving, r f rmatting.
The sequence f the drives in the c mputer that y u are servicing might have been altered. If y u select
an inc rrect drive, data r pr grams might be verwritten.
• Replace an FRU nly with an ther FRU f the c rrect m del.
When y u replace an FRU, ensure that the m del f the machine and the FRU part number are c rrect.
• An FRU sh uld n t be replaced because f a single, unrepr ducible failure.
Single failures can ccur f r a variety f reas ns that have n thing t d with a hardware defect, such as
c smic radiati n, electr static discharge, r s ftware err rs. C nsider replacing an FRU nly when a
pr blem recurs. If y u suspect that an FRU is defective, clear the err r l g and run the test again. If the
err r d es n t recur, d n t replace the FRU.
• Only replace a defective FRU.
Locating FRUs (including RUs)
Notes:
• S me f the c mp nents are pti nal.
• T replace a c mp nent that is n t in the list bel w, c ntact a Len v service technician. F r a list f
