System Battery



A coin-cell battery maintains system configuration, date, and time information. The battery can last several years.



If you have to repeatedly reset time and date information after turning on the computer, replace the battery.



The battery may need replacing if you have repeatedly reset the time and date information after turning on the system or if one of the following messages

appear:



Time-of-day not set - please run SETUP program



Invalid configuration information -

please run SETUP program



To determine whether you need to replace the battery, see "Troubleshooting the System Battery" in "Troubleshooting Your System."



You can operate your system without a battery; however, without a battery, the configuration information is erased if the system is turned off or unplugged

from the electrical outlet. In this case, you must enter the System Setup program and reset the configuration options.



1. Enter the System Setup program and, if possible, make a printed copy of the System Setup screens. See "Using the System Setup Program" in the

User's Guide.

2. Open the system. See "Opening the System" in Troubleshooting Your System."

3. Locate the battery on the system board. See FigureA-3 for the battery location.

4. Remove the battery by pressing on the tab. See Figure6-12.

Figure 6-12. Replacing the Battery



CAUTION: A new battery can explode if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the

manufacturer. Discard used batteries according to the manufacturer's instructions.

CAUTION: Only trained service technicians are authorized to open the system cover and access any of the components inside the system. See

your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against

electrostatic discharge.

NOTICE: If you use a blunt, nonconductive object to depress the tab next to the battery, be careful not to touch the system board with the object.

Ensure that the object is inserted between the battery and the tab before you attempt to depress the tab. Do not pry out the battery. You may

damage the system board by prying off the socket or by breaking circuit traces on the system board.
