Symptoms

  • Red flashing light
  • Drawing no current at 15V from the charging port
  • Sometimes charging, sometimes not

Solution

Check USB-C 5v pins

The laptop might charge occasionally but will not power on. Despite most of the board seeming fine via multimeter, this is usually caused by the charging USB-C port (The secondary USB-C on the right does not provide power.) The blinking light indicates power fluctuation, fix by replacing the port.
