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

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:

      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
