Pop sound when turning on then turns off immediately

[Fckneku]

I always use my laptop everyday and it works very smooth. But yesterday when im trying to use it, It doesnt open.

When I press the power button theres a single pop sound then it turns off immediately. The power button just light up for a second then turns off. 

I remove the ac plug and battery. And try to drain its remaining power then try to open it again. But same problem occurs. 

I also remove hard disk and ram, i also clean the fan then try to open it but still the same problem. 

Whats with this single pop sound? i check the lights for the charger but its all good. 

Thank yoh in advance. Kudos.
