Overview

This document contains step- by-steps disassembly instructions for the Versa M400/PB E asyNoteM5 M7 chassi s.
The inst ructions are illustrated w here neces sary with images of the part that i s bei ng removed or disassemble d.
Furth ermore, the screws that are removed are shown next to the ima ge of the parts themselves.

NEC rese rves the ri ght to make cha nges to the Versa M400 chass is wit hout notice.

Technician Notes

Only technicians aut horized by NE C Computers Interna tional BV shoul d attempt to repair this equipment. All
troubleshooting and repair procedures are d etailed t o al l ow only subas sembly/module level repair. Because of the
complex ity of the i ndi vidual boards and subassemblies, no one should att empt to make r epairs at the component
level or t o make modifications t o any printed wiring board. Improper repairs can cr eate a safety hazard. A ny
indication of component replacement or printed wiring board modifications may void any warranty or ex change
allowances.

Disassembly Instr uctions

When dis assembling the system unit, follow these general rules :

 Do not disassemble the system into parts that are small er than those specified i n the instructions.
 Label all removed connectors. Note wher e the connector goes and in what position it was i nst al l ed.
 Turn off t he power and disconnect al l 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 cables an d screw s are ret urned
to their proper positions. Che ck that no tools or any loose parts have bee n l eft inside the chassis. Check that
everyt hi ng are proper ly install ed and tight en ed.

Required Tools

All disassembly pro cedures can be perform using the following tools:

 PH 0x 60 P hilips screwd river
 PH 0x 40 P hilips screwd river
 4.0 x 60 Fl at screwdriv e r
 2.0 x 30 Fl at screwdriv e r

Hazardous Vol tag e

There is hazardo us vol tage pr ese nt inside the computer
when it i s connect to an AC supply, even when the
computer’ s pow er swi t ch is off. Exposure to haz ardo us
voltage could cause personal injury. To avoid risk of injury,
contact an Authorized Service Provider f or proper
(un)installation of optional hardware devices.

Avoid Electrostatic 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 pr otective pa ck aging whe never they are not
installed i n your system.

Add-in cards can be extremely se nsitive to ESD and always
requi re careful handling. After removing the card fro m the
computer, pla ce the card flat on a ground ed, stati c-f re e
surface, component-side up. Use a conductive foam pad if
available, but not the card wrapper. Do not slide the card
over any surfac e.

Bef ore y ou install or remove memory modules, video
memory, disk drives, circuit 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. Befor e picking up the devi ce y ou
(un)ins t all, you shoul d wear an anti-stati c wrist wrap
(avai la bl e at electro nic supply st ores). Be sure to connect
the wrist wrap to an unpainted metal porti on of t he computer
cha s s is. A s an al ter n at iv e, y o u can di s s ipat e e le ctro s tat ic
build-up by touchi ng an unpaint ed metal porti on 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 ha nd, and mai ntain
continuous contact with it until it is (un)installed in the
computer.

Power Supply Unit

Under no circumstances shou ld you attempt to disassemb l e
the power s upply. 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 person al i njury. Always
return a defe ctiv e power supp ly to your deal er.

WARNING

Ensure that the computer is di sco nnected from
its power s ource and from all
telecom mu nications links, netw orks, or mod em
li ne s whe n ever the ch as s is co v e r i s re m oved.
Do not operate the co mput er wi th the cover
removed.

AVERTISSEMENT

Assure z- vous que le système est débranché de
son alimentation ainsi que de tout es les
liaisons de té léco mmunication, des rése aux, et
des lignes de mode m avant d’en lev er le capot .
Ne pas utiliser le système quand l e capot est
enlevé.

WARNUNG

Das System darf weder an eine Stromquelle
angeschlossen sein noch eine Verbindung mit
einer Telek ommunikati onsei nri chtun g, ei nem
Netzwerk oder einer Modem-Leitung habe n,
wenn di e Gehäuseabdeckung entfernt wir d.
Nehmen Si e das System nic ht ohne die
Abdeckung in Betrieb.

ADVERTENCIA

Asegúr ese de que cada vez que se quite la
cubierta del chasi s, el sistema haya sido
desconectado de la red de ali mentación y de
todos lo enlaces de telecomunic aciones, de red
y de líneas de módem. No ponga en
funciona mie nto el sist ema mient ra s 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)
verbrok en worden v oordat de behuizing
geopen d wordt. Zet de computer nooit aan als
de behuizin g geope nd i s.

AVVERTENZA

Prima di ri mu over e il co perchi o del telai o ,
assicurarsi che il sistema si a scollegato
dall’alimentazione, da tutti i collegamenti di
comunicazione, reti o linee di mod em. Non
avviare il siste ma senza aver prima messo a
posto il coperchio
