Disable UMA on Dell 5482

[Albrie]

Hi, I have GPU problem on Dell Inspiron 5482 laptop - I removed PL8508 + PL8509 to convert to UMA only, but problem was not solved. I then removed PR8502 which is PVCC for PU8514 that provides PWR_VGA_CORE, but problem was still not solved. When I boot safe mode there is no problem? I suspect problem is with UMA graphics because unit has switchable graphics, so it uses UMA on logon screen. I have uninstalled all Nvidia drivers, but still did not work. I want to try disable UMA and force laptop to only use discrete? Is this possible?

i have this schematic bro . if you converted it to uma by remove the gpu core voltage so problem is not in discate graphic .
and in this case maybe uma graphic have problem and you cant disable uma grophic by hardware solution .
