DISASSEMBLY AND REASSEMBLY

This section contains step-by-step disassembly procedures for the system unit. Reassembly
is the reverse of disassembly. A simplified disassembly illustration is provided with most
procedures. At the end of the section there is a parts list and an illustrated parts breakdown
showing an exploded view of the system.
A Phillips-head screwdriver is the only required tool. For complete disassembly of the
system unit, follow the disassembly order listed in Table 5-1. To reassemble, follow the
table and procedures in reverse order.
Individual removal procedures do not require the total disassembly of the computer. Each
of the following subsections lists the parts that must be removed before beginning the
removal procedure.
