Blank screen after disabling onboard graphics

[monstermonroe]

After disabling integrated graphics my screen went blank and now I can’t do anything, I can’t even get into bios or safe mode my screen is completely blank

Unplug pc power. Look for the large watch battery on the motherboard. Pull it out. Push and hold the power button for 10-20 seconds. Put the battery back in. Plug pc power back in

Pc should boot now.

HI, I have already tried this and I am still not getting anything

How did you disable the igpu? Do you have a dedicated graphics card you intend to use instead? Is one installed?

 

[monstermonroe]

I Used device manager because after installing cod ww2 it was running poor then I noticed that in the settings it was using integrated graphics and not my GeForce graphics card

Ok. Where is the monitor connected. It should be connected to the gpu ports. The only way the game should be using the igpu is if the monitor is plugged into the motherboard ports.

I am using HDMI cable

But is the hdmi cable plugged into the motherboard hdmi port, or into the gpu hdmi port.?

If it's plugged into the motherboard port, disabling the igpu, which is part of the cpu and run by the motherboard will mean no picture, blank screen, no bios etc.
If it's plugged into the graphics card, there's a separate issue going on as the graphics card has nothing to do with the motherboard ports or the igpu.
