Hi,
Do a hard reset with it first, remove the battery and AC adapter then press and hold the power button for 20 seconds. Plug just the AC adapter then boot the laptop and see if it loads normally to the desktop. If that doesn't work and you see other light indicator on your keyboard and the fans are all spinning try and connect an external monitor and see if you'll get any display from it. Having a display on the external monitor press the Windows key + P then select "Display Only".
