5. Turn on the sled.
6. Enter the System Setup.
If the date and time are not correct in the System Setup, replace the battery. If the problem is not
resolved by replacing the battery, see Getting Help.
NOTE: If the sled is turned off for long periods of time (for weeks or months), the NVRAM may
lose its system configuration information. This situation is caused by a defective battery.
NOTE: Some software may cause the sled’s time to speed up or slow down. If the sled operates
normally except for the time maintained by the System Setup, the problem may be caused by a
software rather than by a defective battery.

System messages
For a list of event and error messages generated by the system firmware and agents that monitor system
components, see the Dell Event and Error Messages Reference Guide at dell.com/esmmanuals.
Warning messages
A warning message alerts you to a possible problem and prompts you to respond before the system
continues a task. For example, before you format a hard drive, a message warns you that you may lose all
data on the hard drive. Warning messages usually interrupt the task and require you to respond by typing
y (yes) or n (no).
NOTE: Warning messages are generated by either the application or the operating system. For more
information, see the documentation that accompanied the operating system or application.
Diagnostic messages
The system diagnostic utilities may issue messages if you run diagnostic tests on your system. See Using
System Diagnostics. for more information about system diagnostics.
Alert messages
The systems management software generates alert messages for your system. Alert messages include
information, status, warning, and failure messages for drive, temperature, fan, and power conditions. For
more information, see the systems management software documentation.
