Here is a list of troubleshooting steps to identify and address the battery issue with your laptop:

1. Check the power adapter – Make sure the power adapter is securely plugged into the wall and laptop.
   If using a power cord, make sure it is securely plugged into the power adapter and laptop. Try using another power cord or adapter if available.
2. Check the power settings – Review the power settings of the laptop and ensure it is not set to save battery by only running with the adapter plugged in.
3. Start in Safe Mode – Start the laptop in Safe Mode to identify if the issue is software related.
4. Perform a Hard Reset – Shut down the laptop, unplug all power cords, and hold down the power button for 30 seconds. Re-connect the power adapter and power on the laptop to see if the battery is now recognized by the operating system.
