Dell Latitude D830 capacitor broke off of the Graphics NVIDIA G86-920-A2 BGA IC Chip

Does anybody know what the capacitor value would be?
It is located next to the bottom left corner of the mirror, on the only chip labeled NVIDIA, See attachment hopefully.

Just pick one on another chipset

Do you mean any chipset? I don't happen to have another D830 laying around the house

How can you know that's the problem and not the chip itself.

The picture is of an almost identical chip (it was fast to download that find my phone at the time. The chip I have is clearly missing the cap where the arrow is pointing.

Not sure, I was looking into a third party Bios password they forgot. WAVE BIOS. The cap was my fault it disappeared when removing thermal paste that was almost glue as well. I was very hard stuck on like old dry gum. Anyway the cap must have disappeared during that process is all I can tell because I have never seen it pass the extra Bios password.

I've got lots of old g86-620-a2 hanging about.
Its looks pretty much the same as yours.

It will work without that capacitor, don't worry too much about it. For password rewrite BIOS chip on programmer. Black screen means the GPU has failed, those chips are from a known bad lot. Replacing with new one is the only long term solution.
