Determining a Defective Unit

To determine a defective unit:
1. Save and exit from all files, if possible.
2. Shut down Windows NT, if possible.
3. Turn off the power to the monitor and to the system base unit.
CAUTION Always turn off the power to the workstation before connecting or disconnecting the cables.
4. Check and reseat all board and cable connections as needed.
5. Turn on the power to the monitor. If the Power On LED does not illuminate, return the
monitor.
NOTE After a period of inactivity, the monitor enters a power saving mode. On Intergraph Multi-sync
monitors, the Power On LED on the front of the monitor will change from green to yellow to
indicate the power saving mode is active.
6. Turn on the power to the system base unit. If the Power On LED on the base unit does
not illuminate or if the BIOS beep codes indicate a failure, return the workstation.
7. If the monitor display is distorted, ensure the software setup is correct for the monitor
type.
If the software setup is correct, use a similar type monitor (if available and functioning
properly) to determine if the workstation is defective.
