• Use the correct type of onboard CMOS battery as recommended by the manufacturer.
Check to verify that it still supplies approximately 3VDC. If it does not, replace it with a
new one. Warning: To avoid possible explosion, do not install the battery upside down.
• Verify that all jumpers are set to their default positions.
• Check that the power supplies' input voltage operates at 100-120V or 180-240V.
• Turn the power switch ON and OFF to test the system.
No Video
• If the power is ON but you have no video, remove all the add-on cards and cables.
System Boot Failure
If the system does not display POST (Power-On-Self-Test) or does not respond after the
power is turned ON, check the following:
Turn ON the system with only one DIMM module installed. If the system boots, check for bad
DIMM modules or slots by following the Memory Errors Troubleshooting procedure below.
Memory Errors
• Make sure that the DIMM modules are properly and fully installed.
• Confirm that you are using the correct memory. Also, it is recommended that you use the
same memory type and speed for all DIMMs in the system. See
details.
• Check for bad DIMM modules or slots by swapping modules between slots and noting the
results.
• Check the power supply voltage 115V/230V switch.
Losing the System's Setup Configuration
•
Always replace power supplies with the exact same model that came with the system. A
poor quality power supply may cause the system to lose the CMOS setup configuration.
•
Check that the motherboard battery still supplies approximately 3VDC. If it does not,
replace it.
If the above steps do not fix the setup configuration problem, contact your vendor for repairs.
