Sometimes when i press the power button nothing happens

[anandmohan]

Hi,
I have a Omen 15 laptop and sometimes when i press the power button nothing happens, literaly nothing, not even the light turns on or any fans at all. It happens very rarely and has never happened twice in a row. Once it happened also when it was on, i pressed the power button and it didn't respond.
Can this be a physical glitch on the button or something? Or should i worry about a hardware issue?
