Conversion package of 394 KB for a Dell 15 7537, describing how to change the board from discrete graphics (DIS) to integrated graphics (UMA). Such kits usually include marked schematic pages, removal lists for GPU-related parts and sometimes a UMA BIOS or strap resistor changes. Use it when a failed dedicated GPU needs to be bypassed; confirm the motherboard number on the PCB matches, and back up the original BIOS chip with a programmer before writing any modified image.
