Laptop not turning on

Strix g15 ryzen 7 4800h and GTX 1650 ti

The laptop is not turning on , the power indicator does not light up even if charging . The laptop flashes the power light for a brief second at the moment the power is connected and goes dim again ...

Sometime i just let it sit for 4-6 hrs and it generally starts to work again , the laptop is currently not turning on

I have tried unpluging the laptop and holding the power button for a minute or two , and when i connect the charger and try to start it the power light just flashes and the laptop does not turn on .. please help

I have also tried the hard reset when the battery is removed ...

I have look at the forum for any possibile solution .. i have also replaced the motherboard but the same problem persists ...

Any suggestion pls
