Overview
This document contains step-by-step disassembly instructions for the EasyNote BU

Technician Notes
Only technicians authorized by Packard Bell 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 unit, follow these general rules:
n Turn off the power and disconnect all cables.
n Label all removed connectors. Note where the connector goes and in what
position it was installed.
n Do not disassemble the unit 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 product. Check that everything is properly installed
and tightened.
Required Tools
All disassembly procedures can be performed using the following tools:
n Phillips (#1 bit) screwdriver
