Problem

l Error message shows problem with the battery

l System setup program loses the system configuration information

l System date and time will not stay current

The system battery maintains system configuration, date, and time information in a special section of memory 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 lasts longer).

You can operate the system without a battery; however, the system configuration information maintained by the battery in NVRAM is erased each time you

shut down the system. Therefore, you must reenter the system configuration information and reset the options each time the system boots until you replace

the battery.

Action

1. Reenter the time and date through the System Setup program.

2. Turn off and disconnect the system from the electrical outlet for a few hours.

3. Reconnect the system to the electrical outlet and turn the system on again.

4. Enter the System Setup program.

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

If the problem is not resolved by replacing the battery, see "Getting Help," for instructions on obtaining technical assistance.

Troubleshooting Power Supplies

Problem

l Amber fault indicator on the system front panel lights up (redundant only)

l Red fault indicator blinks on the power supply or lights up continuously (redundant only)

l No power

Action

1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

2. For nonredundant system's, remove the system's right-side cover and check that the power connectors are properly connected or if they are loose.

For redundant system's, check that the power supplies are properly installed.

3. Slide the new power supply into the chassis.

4. If you removed the system cover, replace the system cover and connect the system to its electrical outlet.

5. Turn on the system including any attached peripherals.

If the problem persists, see "Getting Help," for information on obtaining technical assistance.

Troubleshooting Expansion Cards

Problem

l Error message indicates an expansion-card problem

l Expansion card seems to perform incorrectly or not at all

Action

1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

2. Remove the right-side cover (see "Removing the Side Covers").

3. Remove the PCI fan shroud (see "Removing the PCI Cooling Shroud" in "Installing System Board Options").

4. Verify that each expansion card is firmly seated in its connector.

5. Verify that any appropriate cables are firmly connected to their corresponding connectors on the expansion cards.

6. Replace the PCI fan shroud (see "Installing the PCI Cooling Shroud" in "Installing System Board Options").

7. Replace the right-side cover (see "Replacing the Side Cover").

NOTE: Some software might 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 might 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 might lose its system configuration information. This

situation is not caused by a defective battery.
