4.4 Troubleshooting
Probable Solution
1. There is no power in the system. Power LED does
not shine; the fan of the power supply does not work
2. Indicator light on keyboard does not shine.
1. Make sure power cable is securely plugged in.
2. Replace cable.
3. Contact technical support.
System is inoperative. Keyboard lights are on, power
indicator lights are lit, and hard drives are running.
Using even pressure on both ends of the DIMM,
press down firmly until the module snaps into place.
System does not boot from a hard disk drive, but can
be booted from opcal drive.
1. Check cable running from disk to disk controller
board. Make sure both ends are securely plugged in;
check the drive type in the standard CMOS setup.
2. Backing up the hard drive is extremely important.
All hard disks are capable of breaking down at any
me.
System only boots from an opcal drive. Hard disks
can be read, applicaons can be used, but system
fails to boot from a hard disk.
1. Back up data and applications files.
2. Reformat the hard drive. Re-install applications
and data using backup disks.
Screen message shows “Invalid Configuration” or
“CMOS Failure.”
Review system’s equipment. Make sure correct
information is in setup.
System cannot boot aer user installs a second hard
drive.
1. Set master/slave jumpers correctly.
2. Run SETUP program and select correct drive types.
Call the drive manufacturers for compability with
other drives.
CPU Overheated
If the system shutdown automacally aer power on system for seconds, that means the CPU
protecon funcon has been acvated.
When the CPU is over heated, the motherboard will shutdown automacally to avoid a
damage of the CPU, and the system may not power on again.
In this case, please double check:
1. The CPU cooler surface is placed evenly with the CPU surface.
2. CPU fan is rotated normally.
3. CPU fan speed is fullling with the CPU speed.
Aer conrmed, please follow steps below to relief the CPU protecon funcon.
1. Remove the power cord from power supply for seconds.
2. Wait for seconds.
3. Plug in the power cord and boot up the system.
Or you can:
1. Clear the CMOS data. (See “Close CMOS Header: JCMOS1” secon)
2. Wait for seconds.
3. Power on the system again.
