Acer Aspire 8530 - without dedicated GPU

[wtracz]

Acer Aspire 8530 / 8530G
ATI HD 3200
ATI Radeon HD 4570
AMD Turion X2 RM-72
In the above-mentioned laptop, the dedicated ATI Radeon HD 4570 GPU is damaged. As the card is on the MXM slot, I decided to remove it and leave only the integrated HD 3200. Everything would be fine if it were not that the laptop turns on without a picture from time to time, the system loading but does not throw the content onto the matrix. Sometimes turning it on, off + removing the battery, but usually the most effective is to insert the old GPU and remove it. Is it possible to somehow completely "switch" this board to work only from an integrated card? maybe you need to disconnect some detection of this card? I suspect that the supply of a dedicated card is on a card with a BGA chip.
I updated the BIOS to the latest version.

I suspect that the supply of a dedicated card is on a card with a BGA chip.

if that was the case the machine would never start. The Big Bear board has RS780 northbridge that contains the IGPU, which is powered from the motherboard.

You should specify the exact platform model and revision. I found only Wistron Big Bear 48.4AJ01.001 https://drive.google.com/file/d/1Z4U...CwgQn0uH8/view

There are straps and pads that can switch this board to internal graphics. Search for "UMA" and "DIS" on the schematics. You will have to solder some jumpers and change/move some resistors and caps.

Or alternatively you could go with a Acer Mobility HD4650 1GB, p/n VG.M9606.005.
