Schematic in PDF form labelled ZQM with the UMA suffix, meaning the design uses integrated graphics with no discrete GPU. ZQM reads like an ODM project code, but the name gives no laptop brand, model or revision, so identify the target from the title block inside the document. A circuit diagram like this lets a technician follow power rails, signal paths and enable lines, and find the parts feeding a dead rail. Make sure the board under repair is also the UMA version before comparing component placement or values.
