You may rely on the accuracy of your Dell Latitude's clock in your home, especially if your computer sits on your kitchen counter. Your computer's CMOS (complementary metal-oxide-semiconductor) powers the CMOS chip. The CMOS chip is a tiny chip built into the Dell motherboard. It stores basic data instrumental to your computer's operation. This includes your computer's date and time settings.

If the CMOS battery dies, your Dell Latitude computer's clock settings will reset each time you restart the computer. Fortunately, replacing your laptop's CMOS battery requires almost no disassembly.
