Question Lenovo Ideapad s540 won’t display when turned on, please help!

May 28, 2020
I recently got a new laptop two weeks ago, but since the past few days, when I turn it on, it just displays a black screen. I’ve tried things like the Shift + F8 method, holding the power button for thirty seconds, and they worked the first time, but after that, it just won’t work anymore. I want to know how I can get rid of this black screen for good, I’d appreciate it if someone would be willing to tell me how.
