There’s a small battery on the motherboard of your computer which keeps important information such as the date and time, your hard drive’s setup, and other vital pieces of information needed by your PC each time it starts (usually referred to as the CMOS RAM). If the backup battery goes dead, you’ll lose the system date and time, and you may have trouble booting the computer. These backup batteries normally last 2-4 years. If your system is more than 3 years old (or your system loses a bit of time when it’s off), you should consider replacing the backup battery. Your system manual will have the specific procedure for you to follow.
