Power button turned on but the screen remains black

I have a lenovo laptop of model E40-70(quite old version).......Actually problem is that when I pressed the power button the indicator light of battery and power remains on but there is a third indicator light probably for the harddisk which remains off.Besides, I have tried hard boot for this issue but did not get worked.
What can be the issue or problem with it?And also suggest any resolution if any........

What do you mean when you say that you've "tried hard boot?" I assume that the display you are referring to is the built-in display? If so, have you tried connecting it to an external display?
