Wall outlet test

To further diagnose power supply issues, plug another device into the same wall outlet where you usually connect your laptop. This step helps determine if the issue lies with the outlet itself. Use a voltage tester to confirm if electricity is flowing correctly from the wall outlet. If necessary, try plugging the laptop adapter into a different wall outlet to test for consistent power supply.

Adapter brick inspection

Inspect the adapter brick closely when troubleshooting power supply issues. Look for any signs of overheating, which could indicate a malfunction. Check the adapter cable for frays or damages that might be disrupting power flow. Ensure that the adapter brick is compatible with your specific laptop model to avoid compatibility issues and potential power disruptions.

Fixing the Power Port

Bent pin fix

Inspect the power connection port with a flashlight for any bent pins. Carefully straighten them using tweezers. Avoid excessive force to prevent further damage.

Double-check the connection between the adapter and laptop to ensure a secure fit. Make sure there is no strain on the adapter plug and power port.

Secure connection

Ensure a snug fit between the broken power adapter and your laptop. Avoid straining the extra power cable while using it.

Battery Troubleshooting
