Checking the CMOS battery status in Windows 11 is a straightforward process that can help you ensure your computer’s time and settings are maintained correctly. By accessing the BIOS settings, you’ll be able to see if your CMOS battery is functioning well. If you notice your computer’s date and time settings keep resetting, it might be time to check the CMOS battery status. Follow the steps below to check it quickly and easily.
Step-by-Step Tutorial to Check CMOS Battery Status in Windows 11
To check the CMOS battery status in Windows 11, you need to enter the BIOS settings of your computer. This is where you can find the information about your CMOS battery.
Step 1: Restart your computer
Restart your computer to access the BIOS settings.
When your computer begins to reboot, you’ll need to be ready to press a specific key to enter the BIOS. This key varies depending on your computer’s manufacturer, but it’s often the Delete, F2, or Esc key. Be prepared to press this key as soon as the computer starts to boot up.
Step 2: Enter BIOS settings
Press the designated key repeatedly to enter the BIOS setup during the boot process.
Once you press the correct key, you’ll enter the BIOS settings. This is a special area of your computer where you can view and change hardware settings, including checking the CMOS battery status. Look for a section labeled “Power Management” or “System Information.”
Step 3: Locate CMOS battery status
Navigate through the BIOS menu to find the CMOS battery status.
Depending on the BIOS version, the CMOS battery status might be under different headings. Use the arrow keys to explore the menus. Look for words like “Battery” or “CMOS” to guide you. If your battery is low, it may display a warning message.
Step 4: Check the battery status
Read the information on the screen regarding the CMOS battery status.
The BIOS screen should provide you with a clear indication of the battery’s health. If it’s low, you may need to replace it soon. The CMOS battery doesn’t recharge, so a low battery might mean it’s near the end of its life.
Step 5: Exit BIOS
Exit the BIOS settings and allow your computer to continue booting into Windows 11.
After checking the CMOS battery status, you can exit the BIOS. Make sure not to change any settings unless you’re sure you know what you’re doing. Usually, pressing the Esc key will prompt you to exit.
After completing these steps, you’ll be able to tell if your CMOS battery is functioning properly and decide if you need to replace it.
