HP Pavilion won’t boot and just a black screen

[Mubin_Raza]

Hi all, so I removed the stock wifi card which as a NGFF type intel card because i wanted to put an egpu on my pavilion.

the problem is as soon as i plus the cable and try to boot it doesn’t boot and only black screen comes up, i don’t have the body of the laptop on so it won’t show the keyboard caps blink if there is any happening and no i cannot put the motherboard back in the usual laptop body because its mounted on a Acrylic sheet and all so i have an external display,  external mouse & keyboard attached.

Also i am running just on dc power without battery.

so my question is since i read whitelisting or basically the motherboard won’s allow me to jnot connect a unauthorised part since i know exp gdc beast is not authorised by HP.

can you help me with a work around ?
