Here is the process for diagnosing a non-responsive laptop before opening it up:
Check the power brick first using a multimeter.
Inspect the charging port to ensure there are no broken pins.
Perform a hard reset by pressing and holding the power button for 30 seconds.
Listen for fan spin to see if the internal components are powering on.
Check the caps lock light to see if it illuminates.
Plug in an external monitor to determine if the issue is actually just a dead laptop screen.
