I am sorry to hear that you are having such trouble. I will try my best to help you out and resolve the problem as quick as possible.
Let me know the make and model of the computer.
Unlug the ac adapter and check if this model has a detachable battery if yes remove it and let me know.
what happens when you remove the battery and push hold the power button for 10 seconds and then try connecting the ac adapter and power on. What happens.
My apology for the delay i had an internet outage for sometime.
Pull the battery, unplug the AC adapter, push and hold the power button for 45 seconds and release the button.
Wait for 3 mins and then connect only the ac adapter and power it on let me know how it goes.
