I have a different problem guys

I have the same NP350v5c
I bought it second hand years ago and it had glued power board
So when i tried opening it i broke the power button board
i need to fix it to get going

The laptop was already not turning on and now this problem
i had the same problem it blinks for a second but it never turns on

i need to first know where is the power junction on the motherboard so that i can short it out and see the others things and hopefully come up to the core of the problem

Please can someone...
