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.

there is no other solution!
if it works even one time it means the solving way is OK.
maybe the problem is motherboard itself and need to change it.
