Thermal Alarms
The VersaView 6300B wall mount PCs have light-emitting diode (LEDs) that
light when the computer reaches its operating temperature limit. See
for where these LEDs are.
Temperatures are measured at two
points on the motherboard; near the
CPU and near the fan. The table at right
lists the thermal limits for both points.
Follow these steps to determine where an operating threshold has been
reached.
1.
Shut down the computer according to
2. Apply power to the computer.
3. During POST, press F2 to access the UEFI set-up utility:
4. On the Main screen, click Advanced.
5. On the Advanced screen, click Thermal.
Use this menu to determine if there is an issue with internal voltages or
component temperatures.
Troubleshooting
Follow these steps to identify and isolate an issue with computer operation.
1.
Shut down the computer according to
2. Disconnect power to the computer.
3. Disconnect all peripheral devices from the computer.
4. If a keyboard and mouse are used, verify that they are properly
connected.
5. If an external display is used, verify that it is properly connected.
6. Connect power to the computer. During POST, one of three events
occurs:
• The startup process is completed.
• A nonfatal error occurs and the related error message is displayed.
• A fatal error occurs and the startup process terminates.
If an issue cannot be identified by the above steps or a fatal error occurs, see
on the back page for technical support.
