Welcome to the  RAMINFOTECH

 

As per the query we understood that you are facing issue with the screen in your Lenovo G50-70 laptop.

 

Perform the power by removing the extrernal devices connected to the system, shutdown the system and removethe battery and adapter. Now press and hold the power button for 30 seconds and connect the battery and adapter and try to power on the system.

 

As you have mentioned that there is no display in the system when you turn on the system are you able to hear the windows login sound? Try to move the lid back n forth and check for the issue.

 

Hope this helps. Do post back if the issue persists.
