PDF of 102 KB, indexed as a schematic, with the name 60CTQ045 as its only identifier. No laptop model, board number or revision is included. The code most plausibly refers to a power semiconductor part, and the document likely shows its pin arrangement and electrical limits. Use it when measuring a suspect component or sourcing an equivalent, and open it in a standard PDF viewer. Always compare the marking on the board part with this code before ordering a substitute.
