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.

Note: Always disconnect the power cord before adding, changing or installing

any hardware components.

Before Power On

1. Make sure no short circuits between the motherboard and chassis.

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

keyboard and mouse.

3. Remove all add-on cards.

4. Install one CPU (making sure it is fully seated) and connect the chassis speaker

and the power LED to the motherboard. (Check all jumper settings as well.)

5. Use only the correct type of CMOS onboard battery as recommended by the

Manufacturer. Do not install the onboard battery upside down to avoid pos-

sible explosion.

No Power

1. Make sure no short circuits between the motherboard and the chassis.

2. Verify that all jumpers are set to their default positions.

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

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

5. The battery on your motherboard may be old. Check to verify that it still supplies

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

No Video

1. If the power is on but you have no video, remove all the add-on cards and

cables.

2. Use the speaker to determine if any beep codes exist. Refer to the Appendix

for details on beep codes.

Losing the System’s Setup Conﬁ guration

1. Ensure that you are using a high quality power supply. A poor quality power

supply may cause the system to lose the CMOS setup information. Refer to

Section 1-6 for details on recommended power supplies.

2. The battery on your motherboard may be old. Check to verify that it still supplies

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

3. If the above steps do not ﬁ x the Setup Conﬁ guration problem, contact your

vendor for repairs.
