Perform Power Reset or Troubleshooting

If your laptop battery shuts down when unplugged, try performing a power reset or troubleshooting to resolve the issue.

First, power reset your laptop by shutting it down completely and unplugging it from the power source. Remove the battery (if possible) and hold down the power button for 30 seconds to drain any residual power. Reinsert the battery (if removed) and plug the laptop back in. Turn it on and see if the issue is resolved.

If the problem persists, you can try some troubleshooting steps. Start by checking the power settings on your laptop to ensure they are configured correctly. You can also update your operating system (e.g., Windows 10 or Windows 11) and drivers to the latest versions to fix any compatibility issues.

Additionally, inspect the battery charger and power cord for any damage or wear and tear. Make sure they are securely connected to the laptop and power source. If you suspect a hardware issue, you may need to contact a professional for further assistance.

If you are comfortable with computer hardware, you can also check the motherboard, chipset, and semiconductor memory for any signs of damage or malfunction. However, proceed with caution as working with these components can be complex.

By performing a power reset or troubleshooting your laptop battery shutting down when unplugged issue, you can potentially resolve the problem and get your device back up and running smoothly.

Consider Battery Replacement or Disconnection

Battery replacement may be necessary if your laptop battery is old or no longer holding a charge. You can check the health of your battery in the system settings of your laptop. If the battery health is low, it may be time to replace it with a new one.

Alternatively, you can disconnect the battery and use your laptop while plugged into a power source. This will allow you to continue using your laptop without the need for a functioning battery.

If you choose to disconnect the battery, make sure to shut down your laptop properly before removing it.

Keep in mind that disconnecting the battery may void any warranty you have on your laptop, so proceed with caution.

If you are unsure about how to replace the battery or disconnect it safely, consider seeking help from a professional or referring to the manufacturer’s guidelines.
