HP Recommended
Operating System: Microsoft Windows 11

Hello,

 

I just replaced the motherboard of an HP Probook 450 G2.

 

The old board had an AMD R5 graphics card and an i3 installed. The new one has an i5 but no AMD chip.

 

After replacing the motherboard the bios and the OS start correctly but impossible to have a display on the laptop screen (not even the bios).

 

When I connect an external screen in VGA I have a display

 

The bios is in last version (1.54), I tried a clearCMOS, updated Intel chipset driver, I cleaned the screen connector on the motherboard but nothing.

 

 

Would you have an idea?

 

Thanks
