How to Check CMOS Battery Status Windows 10
Ever wondered how to check your CMOS battery status on your Windows 10 computer? It’s simpler than you might think. Just follow these steps, and you’ll be able to see if your CMOS battery is in good condition. This is an important task because a failing CMOS battery can cause your computer to lose its BIOS settings, which can lead to boot issues and incorrect system time.
Step by Step Tutorial on How to Check CMOS Battery Status Windows 10
In this section, you’ll learn how to check the status of your CMOS battery on a Windows 10 system. This process involves using built-in system tools and accessing the BIOS/UEFI settings of your computer.
Step 1: Open Command Prompt
Open the Command Prompt by typing "cmd" in the search bar and hitting Enter.
The Command Prompt is the gateway to many system commands. By opening it, you’re taking the first step towards checking your CMOS battery status.
Step 2: Run the wmic Command
Type wmic bios get /format:list and press Enter.
This command fetches the BIOS information from your system. It’s a simple yet powerful command that provides detailed information about your system’s BIOS settings, including the status of the CMOS battery.
Step 3: Look for the "ReleaseDate" Field
After the command runs, look for the "ReleaseDate" field in the output.
The "ReleaseDate" field will give you an insight into when the BIOS settings were last updated. If this date seems off or very recent without you making changes, your CMOS battery might be failing.
Step 4: Reboot and Enter BIOS/UEFI
Restart your computer and enter the BIOS/UEFI settings by pressing the designated key (usually F2, F10, DEL, or ESC) during startup.
Entering the BIOS/UEFI settings allows you to see if your system retains settings after a reboot, which is crucial for determining the health of your CMOS battery.
Step 5: Check System Time and Settings
Within BIOS/UEFI, check the system time and other settings to ensure they are correct.
If the system time and other settings are incorrect or reset every time you reboot, it’s a strong indicator that your CMOS battery needs replacement.
Once you complete these steps, you’ll have a good idea of whether your CMOS battery is healthy or if it needs to be replaced.
Tips on How to Check CMOS Battery Status Windows 10
- Make sure your computer is plugged in while accessing the BIOS/UEFI settings to avoid any potential power issues.
- Take a picture of your BIOS/UEFI settings before making any changes. This way, you can easily restore them if needed.
- Keep a spare CMOS battery handy if your computer is several years old. These batteries are inexpensive and easy to replace.
- If your system time resets every time you reboot, it’s a classic sign that your CMOS battery is failing.
- Regularly update your BIOS/UEFI firmware to ensure optimal performance and compatibility with newer hardware.
