My Lenovo legion laptop from past 2 days was not opening, when I pressed power button the keyboard lights are lit up and system is on but display is black, after watching some videos and forums about solution, I tried all of them but nothing gives permanent solution,after some testing the display is on after i turn my laptop for few minutes (maybe draining some battery, can feel heat at storage section) and plug it to power cable it working and then again when i restart or shutdown, same problem happens again. Please if u know something help me. when my laptop was on i tried all types of software issues and tested hardware can't able to find what is the problem
