1. Check Charger and Connection:
Ensure the charger is working correctly and the connection to the laptop is secure.

• 2. Inspect for Physical Damage:
  Look for any visible damage to the charging port or nearby components.
  
  
  
• 3. Voltage Measurement:
  Use a multimeter to check for 19V at various points in the charging circuit:
  • Charger: Verify the charger is outputting the correct voltage.
    
• Charging Port: Check the voltage at the charging port pins.
  
  
• First MOSFET: Test the source, gate, and drain pins of the first MOSFET.
  
  
  
• 4. MOSFET Testing:
  If the 19V is not present at the drain of the first MOSFET, it could be faulty. Refer to videos explaining how to test MOSFETs.
  
  
  
• 5. Charging IC:
  If the charging IC is overheating, it may need to be replaced. This is a more complex repair.
