Power Issues
Power Does Not Turn On
The power cord may be unplugged or power supply may be broken.
1. Make sure the power cord is properly plugged and power switch is on.
2. Connect a different appliance to the power outlet to see whether it works.
- If the appliance works, the power supply has failed.
- If the appliance doesn’t work, the power outlet has failed.
3. Check whether the system’s fan works.
- If the fan works, the problem is likely to be caused by some reason other than the
Power Supply.
- If the fan does not work, it is likely that the PC Power has failed.
4. Check the output voltage of ADM.
5. Check the PC Power and DDM.
Power Does Not Turn Off
A software error may have occurred, or the PC Motherboard and/or Main Board may have failed.
1. Press and hold the Power Switch for at least 3 seconds, and the power will turn off
automatically.
However, the power will not turn off if hardware such as the printer hasn’t stopped
working yet, or if an OS error has occurred.
2. If the method in "1" fails to turn off the power, it is likely that the PC board and/or BE
board have failed.
