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:
1. Check for any error beep from the motherboard speaker.
•
If there is no error beep, try to turn on the system without DIMM modules installed. If
there is still no error beep, replace the motherboard.
•
If there are error beeps, clear the CMOS settings by unplugging the power cord and
contacting both pads on the CMOS clear jumper (JBT1). Refer to Section 2-8 .
2. Remove all components from the motherboard, especially the SODIMM modules. Make
sure that system power is on and that memory error beeps are activated.
3. Turn on the system with only one SODIMM module installed. If the system boots, check for
bad SODIMM modules or slots by following the Memory Errors Troubleshooting procedure
in this chapter.
Memory Errors
When a no-memory beep code is issued by the system, check the following:
1. Make sure that the memory modules are compatible with the system and are properly
installed. See Chapter 2 for installation instructions. (For memory compatibility, refer to the
"Tested Memory List" link on the motherboard's product page to see a list of supported
memory.)
2. Check if different speeds of SODIMMs have been installed. It is strongly recommended
that you use the same RAM type and speed for all SODIMMs in the system.
3. Make sure that you are using the correct type of ECC DDR4 modules recommended by
the manufacturer.
4. Check for bad SODIMM modules or slots by swapping a single module among all memory
slots and check the results.
Losing the System's Setup Configuration
1. Make sure that you are using a high-quality power supply. A poor-quality power supply may
cause the system to lose the CMOS setup information. Refer to Chapter 2 for details on
recommended power supplies.
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.
3. If the above steps do not fix the setup configuration problem, contact your vendor for
repairs.
