Laptop Not Powering On – Motherboard Power Circuit Diagnosis & Repair

In this video, I demonstrate how I diagnosed and repaired a laptop motherboard with a complete no-power condition. The laptop showed zero response: no LEDs, no charging indication, no startup. Through systematic measurements and proper diagnostics, the fault was traced to the motherboard power supply circuit. In this repair you will see: • How to approach a “dead” laptop with no power • Power rail measurements and fault isolation • Identifying the defective section of the power circuit • Step-by-step board-level repair This video focuses on real troubleshooting logic, not part swapping or guesswork. Many laptops labeled as “dead motherboard” can still be repaired with proper electronic diagnosis. This is an AI-dubbed English version of an original Greek repair video. The repair process, measurements, and conclusions are unchanged.
