How to Fix Acer Swift 7 Battery Not Detected Error in Windows 11

If your Acer Swift 7 laptop shows a “Battery Not Detected” error in Windows 11, it can be frustrating. This issue prevents your device from charging or running on battery power properly. Fortunately, there are several simple steps you can take to resolve this problem.

Understanding the root cause of the error helps in applying the right fix. Often, the problem is related to software glitches or hardware communication issues. This article will guide you through easy-to-follow methods to get your battery detected again.

Each step is explained clearly, so even if you’re not very tech-savvy, you can follow along without confusion. Let’s start by making sure your laptop is ready for troubleshooting.

By the end, you should have a working battery indicator and your Acer Swift 7 back to normal operation on Windows 11.

Quick Note: Prerequisites and Initial Checks

Ensure your laptop is properly connected to power using the original charger and cable.
Check if the battery is physically seated correctly inside the laptop, if accessible.
Restart your laptop before starting any troubleshooting — this can fix minor temporary issues.
Make sure Windows 11 is up to date, as updates often include important fixes.

Step 1: Run the Windows Power Troubleshooter

Windows 11 includes a built-in troubleshooter to identify and fix power-related problems automatically. Running this tool is an easy first step.

Click the Start button and open Settings.
Navigate to System > Troubleshoot > Other troubleshooters.
Find Power in the list and click Run next to it.
Follow the on-screen instructions and apply any fixes suggested by the troubleshooter.

This tool can detect common issues such as battery driver conflicts or power configuration errors.

Step 2: Restart the Battery Driver via Device Manager

Sometimes, Windows may have a problem communicating with your battery hardware due to driver glitches. Restarting the battery driver can help.

Press Windows + X and select Device Manager.
Expand the section titled Batteries.
You will see two devices: Microsoft AC Adapter and Microsoft ACPI-Compliant Control Method Battery.
Right-click on Microsoft ACPI-Compliant Control Method Battery and choose Uninstall device.
Confirm the uninstallation.
Once done, click the Action menu at the top and select Scan for hardware changes. This will reinstall the battery driver.
Restart your laptop and check if the battery is detected.

This step resets the connection between Windows and the battery hardware, which often resolves detection errors.

Step 3: Update Your Laptop’s BIOS

The BIOS controls low-level hardware functions, including battery management. An outdated BIOS can cause battery detection problems.

Visit the official Acer Support website.
Enter your laptop model (Swift 7) and go to the downloads section.
Download the latest BIOS update available for your model.
Carefully follow the instructions provided by Acer to install the BIOS update.
After the update, restart your laptop and check if the battery issue persists.

Updating BIOS should be done cautiously, as improper updates can cause serious problems. Only update if you are comfortable following the manufacturer’s instructions.

Step 4: Check Battery Health Using Acer Care Center

Acer Care Center is a helpful app provided by Acer that can diagnose hardware health, including your battery.

Download and install Acer Care Center from the Microsoft Store, if not already installed.
Open the app and navigate to the Battery section.
Run the battery health check to see if the battery is detected and functioning properly.
If the app reports battery errors or a failure, your battery may need replacement.

Alternative Method: Reset the Embedded Controller (EC)

The Embedded Controller manages battery and other hardware signals. Resetting it can sometimes restore battery detection.

Shut down your Acer Swift 7 completely.
Disconnect the charger and any peripherals.
Press and hold the power button for about 15-20 seconds to discharge residual power.
Reconnect the charger and power on the laptop.
Check if the battery is now detected.

This method acts like a hardware reset for battery-related functions without opening the device.

Frequently Asked Questions (FAQs)

Why does my Acer Swift 7 say “Battery Not Detected”?

This error typically means Windows can’t communicate properly with the battery hardware. It could be due to driver issues, BIOS problems, or battery hardware faults.

Can Windows updates cause battery detection problems?

Occasionally, Windows updates may introduce compatibility issues with battery drivers. Running the troubleshooter or reinstalling drivers often fixes this.

Is it safe to update the BIOS myself?

Yes, if you carefully follow Acer’s instructions. BIOS updates fix hardware compatibility and performance issues but must be done cautiously.
