Troubleshooting Tips

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.

•If you cannot boot into your operating system after you have changed your SATA operation settings, restore your previous SATA operation settings and retry booting into the operating system.

Battery Problems

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

R E P L A C E T H E B A T T E R Y — 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 page 109). If the battery still does not work properly, contact Dell (see page 128).
