I turn my laptop on and the screen stays black. The day before i put it to sleep and it did this. Itsa HP pavillion
When you turn on your laptop do you even see bios screen pop up. If you dont then it may be your display has burnt out. Do you have anything plugged into the laptop like another external monitor? Try removing the battery and then power on.
1) First disconnect the power cord from Laptop 2) Remove the battery pack from laptop 3) Press and Hold the power button of your laptop for 10-15 seconds. And its done. This is a way of bringing your laptop from Sleep Thanks :-)
