Overview

This document contains step- by-steps di sassembly instructions f or the Versa M 400/PB EasyNoteM5 M7 chassis.
The inst ructions are illustrated w here neces sary with images of the p art that is being removed or disassemble d.
Furth ermore, the s crews that are removed are shown next to the image of the part s themselves.

NEC rese rves the right to make changes to t he Ve rsa M400 chassis without noti ce.

Technician Notes

Only technicians authorized by NEC Computers Intern ational BV s hould attempt t o repair this equipment . All
troubl eshooting and repair procedures are d etailed to al l ow only subas sembly/module level repair. Bec ause of the
complexity of the individual boards and sub assemblies, no one shoul d at tempt to make repairs at the component
level or to make modifications to any printed wiring board. Impro per repair s c an create a safety hazard. Any
indication of component replacement or printed wiring board modifications may void any warranty or exchange
allowances.

Disassembly Instr uctions

When disassembli ng the system unit, follow these general rules :

 Do not disassembl e t he system int o parts that are smaller than those sp ecified in the instructions.
 Label al l removed connectors. Note wher e the connector goes and in what position it was inst al l ed.
 Turn off the power and disconnect all power and all options.

Reassembly Instructions

Reasse mbly i s the revers e of the disass e mbly pro cess. Use c are to ensure that all cabl es and screw s are ret ur ned
to their proper positions. Che ck that no tools or any loose parts have been left inside the chassi s. Check that
everyt hi ng are proper ly instal led and ti ghten ed.

Required Tools

All disassembly pro cedures can b e perform using the following tools:

 PH 0x 60 Philips screwdriver
 PH 0x 40 Philips screwdriver
 4.0 x 60 Fl at screwdri ver
 2.0 x 30 Fl at screwdri ver
 SW5.0 Spacer screwdriver
 Small tweezers
 Pin

Hazardous Vol tage

There is hazardo us v oltage pr ese nt insi de the comput er
when it i s connect to an AC supply, even when the
comput er’s pow er swi t ch is off. Exposure to haz ar dous
volta ge could cause personal injury. To avoid ris k of injury,
contact an Authoriz ed Service Provider for proper
(un)installation of optional hardware devices.

Avoid Electrostat ic Discharge

Electro st ati c electri cit y can easily damage cir cui t cards and
integr ate d circui ts (ICs) . To reduce ris k of damage, st ore
them in protective packaging w henever they are not
installed in your system.

Add-in cards can be extremely sensitive to ESD and always
require careful ha ndling. Aft er removing the card from the
computer, pla c e the card flat on a grounded, stat i c-fre e
surface, component-side up. Use a conductive foam pad if
available, but not the card wrap per. Do not slide the card
over any surf ace.

Before you install or remove memor y modules, video
memory, disk drives, circui t cards or other devices, protect
them from static electricity. To do so, make sure your
computer’ s pow er swi t ch is OFF. Then, unpl ug the
computer’ s AC power cord. Before picking up the device you
(un)ins tall, you should wear an ant i-static wrist wrap
(avai la bl e at electro nic supply st ores). Be sure to conne ct
the wrist wrap to an unpainted metal portion of the comp ut er
cha s s is. A s an al ter n at iv e , y o u c a n diss ipat e e le ctr os tatic
build-up by touching an unpai nt ed metal portion of the
computer c hassi s with one hand. The n touch th e devi ce you
are (un)i nstalling w ith the other hand, and mai ntain
continuous conta ct with it until it is (un)installed in the
computer.

Power Supply Unit

Under no circumstances should you attempt to disassemb l e
the power supply. Th e power supply contains no user­servi ceable part s. Insi de the power sup ply are hazar dous
voltages t hat can cause s eri ous pers onal i njury . Always
return a defe cti ve power su pply to your dea ler.

WARNING

Ensure that the computer is disconnected from
its power s ource and from all
telecom mu nicati ons links, networks, or mod em
li ne s whe n e ver t h e chassis c ov e r is re moved.
Do not operate th e comput er wi th the cover
removed.

AVERTISSEMENT

Assure z-vous que le système est débranché de
son alimentation ainsi que de toutes les
liais ons de téléco m muni cati on, des rése aux, et
des lignes de mode m avant d’en lev er le capot .
Ne pas utiliser le sy stème quand le capot est
enlevé.

WARNUNG

Das System darf weder an eine Stromquelle
angeschlossen sein noch eine Ver bindung mit
einer Tele kommu ni kat i onsei nri chtun g, ei nem
Netzwer k oder einer Modem-Leitung habe n,
wenn die Gehäuseab deckung ent f ernt wird.
Nehmen Si e das Syst em nicht ohne di e
Abdeckung in Betrieb.

ADVERTENCIA

Asegúr ese de que cada vez que se qui te la
cubierta del chasi s, el sistema hay a sido
desconectado de la red de alimentación y de
todos lo e nlaces de telecomunicaciones, de red
y de líneas de módem. No ponga en
funciona mie nto el si st ema mientr as la cubiert a
esté quitad a.

WAARSCHUWING

Zorg er voor dat alle v erbindingen van en naar
de computer (st roo m, modem netwerk, etc)
verbroken worden voordat de behuizing
geopen d wordt. Zet de computer nooit aan als
de behuizin g geope nd i s.

AVVERTENZA

Prima di ri m uover e il coperchio de l t elai o ,
assicurarsi che il sistema sia scollegato
dall’alimentazione, da tutti i collegamenti di
comunicazione, reti o linee di modem. Non
avvi are il sistema senza aver prima messo a
posto il coperchio
