Troubleshooting the System Battery

Problem

• System message indicates a problem with the battery
  
  
• System Setup program loses system configuration information
  
  
• System date and time do not stay current
  
  

The system battery maintains system configuration, date, and time information in NVRAM when you turn off the system. The operating life of the battery ranges from 2 to 5 years, depending on how you use the system (for example, if you keep the system on most of the time, the battery gets little use and thus lasts longer). You may need to replace the battery if an incorrect time or date is displayed during the boot routine.

You can operate the system without a battery; however, the system configuration information maintained by the battery in NVRAM is erased each time you remove power from the system. Therefore, you must re-enter the system configuration information and reset the options each time the system boots until you replace the battery.

Action

1. Re-enter the time and date through the System Setup program (see "Using the System Setup Program" in your User's Guide).
   
   
2. Turn off the system and disconnect it from the electrical outlet for at least one hour.
   
   
3. Reconnect the system to its electrical outlet and turn the system on.
   
   
4. Enter the System Setup program.
   
   

If the date and time are not correct in the System Setup program, replace the battery (see "System Battery" in "Installing System Options").

If the problem is not resolved by replacing the battery, see "Getting Help."

NOTE: Some software may cause the system time to speed up or slow down. If the system seems to operate normally except for the time kept in the System Setup program, the problem may be caused by software rather than by a defective battery.

NOTE: If the system 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.

Troubleshooting Redundant Power Supplies

Problem

• Power indicator on the front panel does not light
