Red X on Battery Icon on Windows | Full Guide

Why Is There a Red Cross on the Battery Icon

When you plug in the power and find a red X next to the battery, and your laptop or tablet charges slowly or not at all, you may wonder “why is a red X on my battery icon?” It probably means there is something wrong with the power system of your computer.

The red X on battery icon can be due to several potential problems:

• Battery not detected: Sometimes, the system might not recognize the battery, which will cause the red cross to appear. This may be because the battery is not properly installed, the power supply is not properly connected, the power supply or the battery has been corrupted, etc.
• Driver issues: An outdated or corrupted battery driver can lead to miscommunication between the operating system and the battery, which will cause the red X on battery icon. To avoid this battery display error, you can keep updating your system to ensure the battery driver is in a good state.
• Hardware problems: Issues with the internal charging circuitry of your computer may prevent the battery from charging. This can be due to a damaged charging port, faulty computer components, or a wrong power adapter. In addition, the battery reaching the end of its useful life can also cause the problem. In this case, you need to consider replacing the battery with a new one.
• BIOS-related issues: The outdated BIOS can sometimes cause the system to misread the battery status, and then cause the red X icon to occur. Moreover, incorrect BIOS settings can also affect how the battery is detected and managed. Updating the BIOS to the latest version or resetting the BIOS to default settings may fix such problems.

How Can You Fix Red X on Battery Icon

Fix 1: Check the Connection and Battery

A faulty power adapter or charging cable is a common reason for charging issues. You can check your charger for any visible damage. Or, you can try using a different adapter and cable to see if the problem persists. If your computer charges properly with a different charger, the original adapter should have been corrupted.

Additionally, dust and debris in the charging port can slow down the charging process. You can use a small brush to clean the port gently. Pay attention to avoid using sharp objects that may damage the internal components. 

If the above methods fail to work, check if your computer’s battery is properly installed. Sometimes the battery may be loose for some reason.
