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. Make sure that the +5v standby LED (LE1) is not on. ( *Note: If LE1 is on, it
indicates that Standby PWR is on. Be sure to unplug the power cable before
installing or removing the components.)
2. Make sure that the 8-pin 12v power connector at JPW2 is connected.
3. Make sure there aren't any short circuits between the motherboard and chas-
sis.
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 (-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.
7. Make sure to use the correct type of CMOS battery as specifi ed by the Manufac-
turer. Do not install the battery upside down to prevent possible explosion.
No Power
1. Make sure that there are no short circuits between the motherboard and the
chassis.
2. Make sure that all jumpers are set to their default positions.
3. Check if 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--in this case, you will need to remove
all the add-on cards and cables fi rst.
2. Use the speaker to determine if any beep codes exist. (Refer to Appendix A for
details on beep codes.)
3. Remove all memory modules and turn on the system. (If the alarm is on, check
the specs of the memory, reset the memory or try a different one.)
