Help on what i should do next

I decided to try and start up my old laptop from around 3-4 years ago, i charged it up but the screen wouldn't light up no matter what, but the charge light and power button both lit up so i opened it up to try to see what happened and when i did the strip on the top left popped up. My guess is that it has something to do with the screen not lighting up but i dont know. The model is a lenovo IdeaPad 3-14ADA05 Laptop - Type 81W0 if that helps.
