3-1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you have followed all

of the procedures below and still need assistance, refer to the ‘Technical Support

Procedures’ and/or ‘Returning Merchandise for Service’ section(s) in this chapter.

Always disconnect the AC power cord before adding, changing or installing any

hardware components.

Before Power On

Make sure that the Standby PWR LED (LE2) is not on. (

Note: If LE2 is on,

the onboard power is on. Be sure to unplug the power cable before installing

or removing the components.)

Make sure that there are no short circuits between the motherboard and

chassis.

Disconnect all ribbon/wire cables from the motherboard, including those for

the keyboard and mouse. Also, be sure to remove all add-on cards.

Install a CPU and heatsink (-be sure that it is fully seated) and then connect

the chassis speaker and the power LED to the motherboard. Check all jumper

settings as well.

No Power

Make sure that there are no short circuits between the motherboard and

chassis.

Make sure that all jumpers are set to their default positions.

Check if the 115V/230V switch on the power supply is properly set.

Turn the power switch on and off to test the system.

The battery on your motherboard may be old. Check to make sure that it still

supplies ~3VDC. If it does not, replace it with a new one.
