 How to Troubleshoot  Dell Laptop with Blinking Power Light

1. Check Power Supply: Make sure the laptop is connected to a working power outlet and the power adapter is securely plugged into both the laptop and the outlet. If possible, try using a different power outlet or power adapter to rule out any issues with the power source.

3. Inspect Battery: If your Dell laptop has a removable battery, remove it and then reinsert it firmly. Ensure that the battery contacts are clean and free from dust or debris. If the battery is old or damaged, consider replacing it with a new one.

5. Perform Hard Reset: Shut down the laptop and disconnect the power adapter. Remove the battery (if removable).

Try turning on the laptop again.
