Question Blinking Power Button on HP 650 G1

[Hextus]

Hello, so I swapped motherboard with second hand because my motherboard died. When I turned on notebook first time everything was working good for 5minutes then it turned off by itself and now I cant turn it on and all it is doing is blinking power button. Thanks for help.

Could be replacement motherboard is bad or something was not right during the setup of it. No really good way to check anything without having the system to look at and check over.
