How to Repair a Dell G15 5525 Laptop with No Power Issue

  1. Identify the Issue: The customer reported that the Dell G15 5525 laptop, equipped with Ryzen 7 and RTX Graphics, was not powering on.

  2. Inspect the Laptop: Before pressing the power button, check if anything happens when the laptop is plugged in. If there is no response, it indicates a potential issue with the motherboard.

  3. Open the Laptop: Remove the screws to access the motherboard. Based on the components observed (resistors, mosfets, capacitors), determine if there is a short circuit on the motherboard.

  4. Diagnose the Short Circuit: Use a thermal camera to identify components that are getting warm, indicating a potential short circuit. In this case, the faulty component was a mosfet that was shorted to the power rail.

  5. Replace the Faulty Component: Desolder the faulty mosfet and replace it with a new one. Ensure the replacement component is soldered back correctly onto the motherboard.

  6. Test the Laptop: After replacing the faulty component, power on the laptop and observe if it functions properly without any short circuits causing overheating.

  7. Address Looping Issue: If the laptop continues to loop or not power on correctly, consider checking the battery charge level. Sometimes a discharged battery can cause looping issues. Try plugging in the charger to see if the laptop stabilizes.

  8. Verify Functionality: Once the laptop stops looping and powers on correctly, check if all components are functioning as expected. Ensure that the CPU and GPU are not overheating and that the laptop boots up properly.

  9. Final Testing: Turn off the laptop, then power it on again to confirm that the issue has been resolved. If the laptop powers on consistently and displays the screen, the repair was successful.

  10. Completion: Reassemble the laptop by securing all components back in place. Test the laptop thoroughly to ensure that it operates without any further issues.
