While you respond to that, let's try a hard reset -

3) Remove the Battery.

Note - This step is not applicable for PCs with built-in battery. 

4) Press and hold down the power button for 15 to 20 seconds.

5) Plug-in the Adapter and put the Battery back into the computer.

6) Try to turn on the computer.

If the issue still persists, try these steps -
