Removing LCD Status Messages For faults associated with sensors, such as temperature, voltage, fans, and so on, the LCD message is automatically removed when that sensor returns to a normal state. For example, if temperature for a component goes out of range, the LCD displays the fault; when the temperature returns to the acceptable range, the message is removed from the LCD. For other faults, you must take action to remove the message from the display: • Clear the SEL - You perform this task from the system management software, but you will lose the event history for the system. • Power cycle - Turn off the system and disconnect it from the electrical outlet; wait approximately ten seconds, reconnect the power cable, and restart the system. Either of the preceding actions will remove fault messages and return the status indicators and LCD colors to the normal state. Error messages will reappear under the following conditions: • The sensor returns to a normal state but fails again, resulting in a new SEL entry. • A new error event is detected. • A failure is recorded from another source that maps to the same display entry. System Messages System messages appear on the screen to notify you of a possible problem with the system. Table 1-5 lists the system messages that can occur and the probable cause and corrective action for each message. NOTE: If you receive a system message that is not listed in Table 1-5, check the documentation for the application that is running when the message appears or the operating system's documentation for an explanation of the message and recommended action. CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge. Table 1-5.
