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

1.Check that the onboard power LED is lit (DP2 on the motherboard).

2.Make sure that the power connector is connected to your power supply.

3.Make sure that no short circuits exist between the motherboard and chassis.

4.Disconnect all cables from the motherboard, including those for the keyboard and mouse.

5.Remove all add-on cards.

6.Install a CPU and heatsink (making sure it is fully seated) and connect the internal (chassis) speaker and the power LED to the motherboard. Check all jumper settings as well.

7.Use the correct type of onboard CMOS battery (CR2032) as recommended by the manufacturer. To avoid possible explosion, do not install the CMOS battery upside down.

No Power

1.Make sure that no short circuits exist 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.
