Hello I need your help, I have an Ideapad 330s -15arr, and I don't know what happened but the screen stay total black, the keyboard seems unresponsive,only the led light of the power button is on.
I can only hear the fan going full speed. I remember that the last days that was working the task manager always said 100% usage of cpu even with few programs open. Maybe it's a ram or cpu problem.
I tried to connect a tv with hdmi cable but didnt work, I tried pressing power button for 60 seconds few times but didn't work. I tried combinations of keys like fn+f8 fn+f12, ctrl+ shift+ win +b. Still nothing.
I can see for a split of second a retro light on the screen while i turning it on but still staying black. Any ideas?
