Troubleshooting
Common Issues and Solutions:
- Battery Not Recognized by Laptop:
If the laptop does not recognize the new battery after installation, try the following:

- Disconnect the new battery, then hold down the laptop's power button for 20 seconds to drain any residual power. Reconnect the new battery and attempt to power on.
- Battery Not Holding Charge / Short Battery Life:
Ensure the battery has undergone the initial calibration cycles as described in the "Setup and First Use" section. If the issue persists, verify that your laptop's power settings are optimized for battery life. Excessive background processes or high screen brightness can significantly reduce battery runtime.
