When My Computer Starts, It Says 'Check the Date and Time'

If your computer displays the 'Check the Date and Time' message every time you start it, don't panic. This guide will walk you through the steps to resolve this issue and ensure your system runs smoothly.

1. Check and Adjust BIOS/UEFI Date and Time Settings

The most common reason for this message is that the BIOS or UEFI settings have incorrect date and time values. Here's how to address this issue:

Access the BIOS/UEFI Setup: When your computer starts, press one of the following keys typically within the first few seconds: F2 - For BIOS on most systems Delete - For UEFI systems that emulate BIOS Esc - For some UEFI systems Look for the Date and Time section. Here, you can adjust the current date and time to match your system clock. Save your changes and exit the BIOS/UEFI setup. The exact steps to save and exit will vary based on the manufacturer.

2. Replace the CMOS Battery (CR2032)

If changing the date and time does not resolve the issue, the problem might be related to the CMOS battery, which can cause the date and time to reset. Here's what to do:

Power Off and Unplug Your Computer: Before opening the case, ensure the computer is powered off and unplugged. Open the Computer Case: Carefully remove the side panel to access the motherboard. Locate the CMOS Battery: It is usually a small, round battery on the motherboard, often labeled 'CMOS.' It is typically either a CR2032 or CR2016 battery. Remove the Old Battery: Use a small tool, such as a screwdriver or needle-nose pliers, to remove the old battery. Install a New Battery: Carefully insert a new CR2032 battery into the socket, ensuring it is facing the correct direction. Reassemble the Computer: Put back the side panel and reconnect the power supply. Power On and Adjust BIOS/UEFI Settings: Reboot your computer and remember to reset the date and time if necessary.

Note: If the issue persists, it is possible that there may be a problem with the motherboard or a corrupted BIOS. In such cases, seek professional help or consult the motherboard manual.

Additional Troubleshooting Steps

If neither of the above solutions resolves the issue, consider the following:

Flashing the BIOS

If you suspect that the BIOS is corrupted, you may need to flash the BIOS to a newer firmware version. This is often a last resort and should be attempted only if you are comfortable with the process, as errors can render your system inoperable.

Checking Jumper Settings for CMOS Reset

Some motherboards have a jumper labeled 'CLR_CMOS' that can be used to clear the CMOS settings. Place the jumper on the appropriate pins (1 and 2, 2 and 3) to reset the CMOS. After doing this, shut down the computer, unplug it, and press the power button for 10 seconds to drain any remaining charge. Replug the power and reboot.

Conclusion

By following these steps, you should be able to resolve the 'Check the Date and Time' message and ensure that your computer retains the correct date and time settings. If the issue persists, seek technical assistance.

Key Takeaways: Access the BIOS/UEFI setup to adjust the date and time. Replace the CMOS battery if the date and time are still incorrect. Check jumper settings if you suspect an issue with the CMOS reset.
