Packard Bell EasyNote B3 Disassembly Manual
Overview
This document contains step-by-step disassembly instructions for the EasyNote B3 chassis. The
instructions are illustrated where necessary with images of the part that is being removed or
disassembled. Furthermore, the screws that are removed are shown next to the image of the parts
themselves.
Packard Bell reserves the right to make changes to the EasyNote B3 chassis without notice.
Technician Notes
Only technicians authorized by NEC Computers International B.V. should attempt to repair this
equipment. All troubleshooting and repair procedures are detailed to allow only subassembly/module
level repair. Because of the complexity of the individual boards and subassemblies, no one should
attempt to make repairs at the component level or to make modifications to any printed wiring board.
Improper repairs can create a safety hazard. Any indication of component replacement or printed wiring
board modifications may void any warranty or exchange allowances.
Disassembly Instructions
When disassembling the system unit, follow these general rules:
2
n Turn off the power and disconnect the AC adapter, and all cables and peripherals.
n Remove the battery: Unlock both latches of the battery compartment and slide out the battery.
n Label all removed connectors. Note where the connector goes and in what position it was
installed.
n Do not disassemble the system into parts that are smaller than those specified in the
instructions.
Reassembly Instructions
Reassembly is the reverse of the disassembly process. Use care to ensure that all cables and screws are
returned to their proper positions. Check that no tools or any loose parts have been left inside the
chassis. Check that everything is properly installed and tightened.
Required Tools
All disassembly procedures can be performed using the following tools:
n Small Philips screwdriver
n Flat-head screwdriver
n Hex bolt screwdriver

Hazardous Voltage
There is hazardous voltage present inside the
computer when it is connected to an AC supply, even
when the computer’s power switch is off. Exposure to
hazardous voltage could cause personal injury. To
avoid risk of injury, contact an Authorized Service
Provider for proper (un)installation of optional
hardware devices.
Avoid Electrostatic Discharge
Electrostatic electricity can easily damage circuit cards
and integrated circuits (ICs). To reduce risk of
damage, store them in protective packaging whenever
they are not installed in your system.
Add-in cards can be extremely sensitive to ESD and
always require careful handling. After removing the
card from the computer, place the card flat on a
grounded, static-free surface, component-side up. Use
a conductive foam pad if available, but not the card
wrapper. Do not slide the card over any surface.
Before you 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 power switch is OFF. Then,
unplug the computer’s AC power cord. Before picking
up the device you (un)install, you should wear an antistatic wrist wrap (available at electronic supply stores).
Be sure to connect the wrist wrap to an unpainted
metal portion of the computer chassis. As an
alternative, you can dissipate electrostatic build-up by
touching an unpainted metal portion of the computer
chassis with one hand. Then touch the device you are
(un)installing with the other hand, and maintain
continuous contact with it until it is (un)installed in the
computer.
WARNING
Ensure that the computer is disconnected
from its power source and from all
telecommunications links, networks, or
modem lines whenever the chassis cover is
removed. Do not operate the computer with
the cover removed.
AVERTISSEMENT
Assurez-vous que le système est
débranché de son alimentation ainsi que de
toutes les liaisons de télécommunication,
des réseaux, et des lignes de modem avant
d’enlever le capot. Ne pas utiliser le
système quand le capot est enlevé.
WARNUNG
Das System darf weder an eine
Stromquelle angeschlossen sein noch eine
Verbindung mit einer
Telekommunikationseinrichtung, einem
Netzwerk oder einer Modem-Leitung haben,
wenn die Gehäuseabdeckung entfernt wird.
Nehmen Sie das System nicht ohne die
Abdeckung in Betrieb.
ADVERTENCIA
Asegúrese de que cada vez que se quite la
cubierta del chasis, el sistema haya sido
desconectado de la red de alimentación y
de todos lo enlaces de telecomunicaciones,
de red y de líneas de módem. No ponga en
funcionamiento el sistema mientras la
cubierta esté quitada.
WAARSCHUWING
Zorg er voor dat alle verbindingen van en
naar de computer (stroom, modem,
netwerk, etc) verbroken worden voordat de
behuizing geopend wordt. Zet de computer
nooit aan als de behuizing geopend is.
Power Supply Unit
Under no circumstances should you attempt to
disassemble the power supply. The power supply
contains no user-serviceable parts. Inside the power
supply are hazardous voltages that can cause serious
personal injury. Always return a defective power
supply to your dealer.
