Motherboard schematic in PDF covering the PLF, PLR, CSF and CSR project codes in their UMA variant, meaning integrated graphics with no discrete GPU. Apart from these codes and the UMA designation, the file name gives no brand, board number or revision. Compare the project code printed on the PCB with the schematic title block before relying on it. Technicians use a drawing like this to follow power rails, the power-on sequence and signal paths, and to find which components sit on a rail that shows a short. Any PDF reader will open it.
