There is a switch inside the holes  below the touchpad which senses when the lid is latched or closed . If the switch is stuck, the laptop may not turn on properly. Check to make sure the switch is working properly.If so, as the first step of diagnostics, you might need to clean the trapped dirt.

NOTES:

  • Make sure you use the correct AC adapter that suits your laptop and avoid 3rd party replacement adapters. Use the manufacturer manual to choose the right adapter.
  • Avoid using extension cords and surge protectors.
  • Check for a loose connection at your DC jack. If so, it might require a service or replacement.
