I have a Toshiba Satellite laptop mg3520 (Windows 10) and the screen won't come on. The power button lights up with battery in but the small light on the front (power or charged, I assume??) won't light up until plugged into power. It sounds like it's powering up but when I try number or caps lock just to see if will light up, nothing. A lot of the small pieces of plastic the screws screw into to hold it together are broken so I basically have to tape it together with electrical tape! Im sure that could have something to do with it. It worked fine 2 days ago. I was on it & sat it down for maybe 5 mins. and the screen never came back on.I have tried to take the battery out, unplug the power, and hold the power button for 30 seconds and it still won't come on. Also tried holding f8, shift & power. I saw something about fn + f4? But I'm thinking none of that will work if the keyboard isn't functioning. Idk! I'm so lost!
