Does the drive light flash showing that Windows is loading?

Have you tried connecting the laptop to an external monitor or TV to see if anything displays on the screen?

Hopefully your laptop just needs a reset of the BIOS.

This video shows you how to open the case.

Click here.

Unplug the charger before you do anything.

Once the case is open don't take the main battery out just disconnect it.

Then take out the CMOS "coin" battery as in this video

Click here

Press the power button for 30 seconds to discharge any residual power, reinstall the CMOS battery and temporarily replace the bottom cover. Plug in the charger and press the power button. Does anything appear on the screen? If yes then uplug the charger, take cover off again, reconnect the main battery and test with battery. If powers on with screen on then battery is good. Reassemble and you are good to go.
