18. Non-Functioning Device

Non-functioning device.

Turn off power, disconnect power cord, and open the computer.

Caution: Power is continuous to the system board and power supply even when the power switch is turned off. To prevent damage to the unit, disconnect the power cord from the power source or the unit before beginning disassembly procedures.

Unplug the power and data cable from the non-functioning device. Inspect cables and plugs for bent or broken pins or other damage. For a NIC or SCSI controller, remove the expansion card and inspect leads.
