Schematic for the Dell XPS M1330, project Thurman, in the discrete graphics version, archived as a 1.50 MB RAR. Discrete indicates the variant with a dedicated GPU rather than integrated graphics, so GPU power and VRAM sections are included. Use it to trace rails, check the graphics core supply and locate components on that board. Since the integrated version differs, confirm your board has the separate GPU fitted before relying on it. Unpack with WinRAR or 7-Zip.
