Thank you for the information. Yes you may try to connect an external monitor and check for the display.
I would suggest you to drain the residual power from the laptop:
- Disconnect any external peripherals (flash drives, printers, external hard drives) from the computer
- Remove the power adapter.
- Hold down the power button for 10 seconds
- Plug in the power adapter.
- Power on the system.
Keep me posted with the results. I will be glad to assist you.
