So I dropped my phone and broke the power button. I'm not sure if it's because my laptop is slow but I tried to turn it on by holding the volume down button plugging it into my laptop via USB and nothing...it's just black screen. I have an LED charger cord that shows me it is fully charged. Could it be the phone or my dinosaur slow laptop. I used to be able to use my pocket knife on the edge of the power button but that's not working anymore
