6-2 Minitower Repair

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.

All screws are Phillips-head, unless otherwise specified.

Label all removed connectors. Note where the connector goes and in what posi-
tion it was installed.

On completion of any reassembly, perform a power-on test (see “Check” in Section 2). If a
fault occurs, verify that the reassembly was performed correctly.

CAUTION:

When handling boards or chips,

ground yourself to release static.
