Disassembly 2: Disassembly Overview This chapter provides step-by-step instructions for disassembling parts and subsystems. When it comes to reassembly, reverse the procedures (unless otherwise indicated). We suggest you completely review any procedure before you take the computer apart. To make the disassembly process easier each section may have a box in the page margin. Information contained under the figure # will give a synopsis of the sequence of procedures involved in the disassembly procedure.
Disassembly NOTE: All disassembly procedures assume that the system is turned OFF, and disconnected from any power supply, and that all peripheral cables are disconnected (including telephone lines and network cables). Maintenance Tools The following tools are recommended when working on the computer: 2.Disassembly • • • • • • M3 Philips-head screwdriver M2.
Disassembly Maintenance Precautions The following precautions are a reminder. To avoid personal injury or damage to the computer while performing a removal and/or replacement job, take the following precautions: Power Safety Warning Before you undertake any upgrade procedures, make sure that you have turned off the power, and disconnected all peripherals and cables (including telephone lines). It is advisable to also remove your battery in order to prevent accidentally turning the machine on.
