![]() ![]() The CMOS battery’s principal purpose is to store BIOS settings and maintain track of your System’s hardware drivers. Its dependability and lifespan depend on how frequently the computer is plugged in, as its primary power source maintains it charged. So, after all the narrative discussion, a CMOS battery could last up to ten years. If that were the case, restarting would result in a “dead CMOS battery” warning, and the device would never function again. It could result in a BSOD if it somehow fries itself and emits a pulse of extremely high voltage and current. FAQsĮxperiencing BSOD is one of the last things you would ever expect from a typical CMOS battery. So you can determine if your CMOS lasts longer or shorter because it depends on how you handle your device. A CMOS battery failure can result in booting difficulties due to improperly functioning hardware drivers. Therefore, the CMOS battery can’t withstand the constant current drain and rising temperature. The temperature inside computers is typically higher than in a typical office or home, leading to a higher self-discharge rate of your CMOS battery. As BIOS is forced to maintain drivers and hardware issues, a dead or near-dead CMOS battery may prevent the System from connecting to the internet.Alternatively, the peripheral keys appear out of alignment, the cursor behaves strangely, and the OS reacts solely to your key inputs.If the CMOS battery fails, it can no longer set the correct date and time, so it keeps resetting every time you shut down the gadget.When the CMOS battery nearly dies, the computer loses some of its hardware recognition due to uncooperative drivers.Here are some symptoms you should notice and can blame your CMOS battery: Is your motherboard constantly producing noise? A continual beeping noise from the hardware indicates that your CMOS battery needs to be replaced. The CMOS battery is also in charge of maintaining the computer’s time and date systems.It also maintains data flow settings between the Operating System and other connected hardware, such as hard drives, mice, keyboards, printers, and video adapters. After booting, the CMOS battery powers the BIOS chip, which starts the computer system. ![]() This chip typically can provide power for at least a year.
