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 non hot-swap hardware components.
Before Power On
1. Make sure that there are 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 the CPU (making sure that it is fully seated) and connect the front panel
connectors to the motherboard.
No Power
1. Make sure that there are no short circuits between the motherboard and the chassis.
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.
No Video
1. If the power is on, but you do not have video, remove all add-on cards and cables.
2. Remove all memory modules and turn on the system (if the alarm is on, check the
specs of memory modules, reset the memory, or try a different one).
