5-2 Disassembly and Reassembly
This section contains step-by-step disassembly procedures for the system unit.
Reassembly is the reverse of disassembly. The procedures are supported by
simplified disassembly illustrations to facilitate removal.
A Phillips-head screwdriver is the only required tool. For complete disassembly
of the system unit, follow the disassembly order listed in the following table. To
reassemble, follow the table and procedures in reverse order.
Individual disassembly 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 disassembly procedure.

When disassembling the system unit, follow these general rules.
Disconnect all peripherals.
When handling boards or chips, touch the system unit frame to discharge
static.
Do not disassemble parts other than those specified in the procedure.
Use a Phillips-head screw driver, unless otherwise specified.
Label all removed connectors. Note where the connector goes and in
what position it was installed.
On completion of any reassembly, perform a power-on self-test (see
Section 4, “Maintenance and Troubleshooting”). If a fault occurs, verify that the
reassembly was performed correctly.
