Why is my MacBook Air 2014 not powering up?

I decided to restore my MacBook Air 2014 few hours ago, after wiping the HDD through the Disk Utility, I tried to re-install the OS X and it started the update for a while and all of a sudden the screen just went black and it didn’t come back up again. I tried to press down the power button for it to power on but nothing seems to be working as the system refuses to power up at all since. Please has anyone ever encountered this issue before?
