Laptop Displays Black Screen

My Toshiba Satellite has recently been having a bizarre issue that I haven’t been able to find anything about. When I press the power button, the power and battery indicator lights come on, but the laptop itself just shows a black screen. I opened it up and found that the laptop doesn’t seem to actually be turning on, as the fan isn’t even running. Prior to this, I had been having other strange issues. My laptop would inexplicably wake up from sleep mode even while closed and, only a day or two ago, would not let me sign in. The night before noticing the black display issue, the aforementioned “waking up while asleep issue occured”, and it displayed the black screen when turned on.

I’ve tried taking the battery out and unplugging it from the AC cable, I’ve tried a different AC cable, I’ve tried holding the power button down for 60 seconds and, so far, nothing has worked. Any help appreciated!
