How to Fix Laptop battery light blinking while charging in Windows 11

It is important that before proceeding with further troubleshooting steps, we suggest that you search for Windows Update. Since there may be a Windows update available, if applicable, install it. Once this is done, you can follow the instructions explained below:

Power Source Confirmation: Ensure a secure connection between the charger and your laptop. Verify that the wall outlet is functioning properly. If possible, test with a different outlet to rule out external power issues.

System Restart: A simple system restart can often resolve temporary software glitches that might be causing the charging irregularity.

Battery Calibration (if applicable):  Certain laptops possess built-in battery calibration utilities designed to maintain accurate battery health reporting. Consult your device's manual for specific instructions on accessing and running this utility.

Fast Startup Deactivation:  The Windows 11 Fast Startup feature can occasionally interfere with the charging process. 

Access the Control Panel by searching for it in the Start menu.

Navigate to "Hardware and Sound" -> "Power Options."

Click on "Choose what the power buttons do."

Select "Change settings that are currently unavailable."

Uncheck the box next to "Turn on fast startup (recommended)" and save the changes.

Battery Driver Updates:  Outdated battery drivers can lead to charging problems. 

Right-click on the Start menu and select "Device Manager."

Expand the "Batteries" section and right-click on your battery device.

Select "Update driver" and choose "Search automatically for updated driver software."

BIOS Update (Advanced): An outdated BIOS might contribute to charging issues.  Caution: Incorrect BIOS updates can cause serious problems.  Consult your laptop's manual or manufacturer's website for specific instructions on updating the BIOS if you are comfortable performing this procedure.

Hard Reset:  A hard reset can clear temporary hardware glitches that might be hindering the charging process.  The specific method varies depending on the laptop model.  Consult your device's manual for instructions. Important:  Performing a hard reset might erase unsaved data.

Hibernate Mode Deactivation:  Hibernate mode can sometimes interfere with charging. Here's how to disable it:

Open Command Prompt as administrator.

Type the following command and press Enter: powercfg /h off

CMOS Battery Clearing (Advanced): The CMOS battery stores BIOS settings.  Removing it for a short time can reset these settings to defaults.  

Caution: This process requires opening your laptop and might void your warranty.  Consult your laptop's manual or a professional if needed.

If the aforementioned steps fail to resolve the issue, consider:

Battery Replacement: Over time, batteries naturally lose their capacity. Replacing the battery might be necessary if it has reached the end of its lifespan.

Professional Repair: If the issue persists after attempting these troubleshooting steps, seek assistance from a qualified computer repair technician to diagnose and potentially fix any underlying hardware problems.

To prolong battery life, avoid using your laptop extensively while it's charging, as heat can damage the battery.

Whenever possible, maintain a moderate battery charge level (between 20% and 80%) to optimize battery health.

We hope you can effectively diagnose the cause of the blinking battery light and restore proper charging functionality on your Windows 11 laptop. If you are unsure about any procedure, please consult your laptop manual or a qualified technician to help you. Get professional guidance.
