HP omen 15 laptop doesn't turn on

[JackX4]

Laptop wouldn't turn on when I tried pressing the power button. When I connect the charger I get an orange blinking light (about 4 seconds on and 1 second off) on the charging port led, it turns to blinking white after prolonged charging. When I try to connect my phone to the power share USB at the back, it just repeatedly starts and stops charging my phone.  Since I'm out of warranty I opened it up to see if its a problem with the power button switch cable, when I disconnected the cable from the motherboard and reconnected it, the laptop powered on but then powered off after a second.  Any one ever ever experienced something like this, and if so what was the problem ?  was it fixable without having to replace the entire motherboard?
