Follow these tips when you troubleshoot your computer:
If you added or removed a part before the problem started, review the installation procedures and ensure that the part is correctly installed.
If a peripheral device does not work, ensure that the device is properly connected.
If an error message appears on the screen, write down the exact message. This message may help technical support personnel diagnose and fix the problem(s).
If an error message occurs in a program, see the program's documentation.
CAUTION: There is a danger of a new battery exploding 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: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.
Replace the battery — If you have to repeatedly reset time and date information after turning on the computer, or if an incorrect time or date displays during start-up, replace the battery. See "Replacing the Battery." If the battery still does not work properly, contact Dell.
If your primary hard drive is connected to a drive controller card and not to one of the system board IDE connectors, leave the drive controller card installed in the computer.
