Symptom
Check point
No Power
(FAN is not
spinning)
* Make sure that no short circuit exists between the mainboard and
chassis
* Check that all jumpers are set to their default positions.
* Check that the 115V/230V switch on the power supply is properly
set.
* Check that the CPU is properly inserted in the CPU socket.
* Check that the power connector of the CPU fan is plugged in the
correct position.
* Turn the power switch ON and OFF to test the system.
* Check the power of the battery on the mainboard.
(In general, the battery voltage is around 3VDC)
Able to power
ON the system
(FAN is spinning),
but NO screen
display.
* Disconnect and remove all components from the mainboard except
for the CPU, memory modules, and the CPU fans.
* Check that the memory is Registered ECC DIMM. Refer to Appendix
A: Recommended Memory Modules or contact your authorized dealer
for a list of qualified memory vendors and models.
* Check that all jumpers are set to their default positions.
* Clear the CMOS through the Clear CMOS header.
* Check that the onboard VGA port and the monitor are properly
connected.
* Use the onboard speaker to aide in determining the problem.
Memory Error(s) * Check that the memory DIMM modules are inserted properly into the
DIMM sockets.
* Check to see if different speed memory modules are mixed in and
used in the motherboard memory banks. Verify that the BIOS setup is
configured for the fastest speed of RAM used. Arima recommends that
you always install the same speed DDR RAM in your system.
* Make sure all your memory modules in the motherboard are
compliant with the PC2100/PC2700 (DDR266/DDR333) Specifications
and that they appear either in Appendix A: Recommended Memory
Modules or on your authorized dealer's Qualified Vendor's List of
Memory Modules.
