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 +5v standby LED is not lit (LE2 on motherboard).
2. Make sure that the 4-pin 12v power connector at J24 is connected to
your power supply.
3. Make sure that there are no short circuits between the motherboard
and chassis.
4. Disconnect all ribbon/wire 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 chassis speaker and the power LED to the motherboard. Check
all jumper settings as well.
No Power
1. Make sure that there are no short circuits exist between the motherboard
and the chassis.
2. Check if all jumpers are set to their default positions.
3. Make sure 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.

and cables.
