Overview
This document contains step-by-step disassembly instructions for the EasyNote W3
(Dragon A) chassis. The instructions are illustrated where necessary with images of the
part that is being removed or disassembled.
Packard Bell reserves the right to make changes to the chassis without notice.
Disassembly Instructions
When disassembling the system unit, follow these general rules:
nTurn off the power.
nDisconnect the AC adapter.
nRemove the battery.
nDo not disassemble the system into parts that are smaller than those specified
in the instructions.
nLabel all removed connectors; note where the connector goes and in what
position it was installed.
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:
nPhilips (#2 bit) screwdriver
nHex 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 anti-static 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.
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.
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.
