Laptop schematic in PDF for the HP ProBook 4540s. The name does not give the ODM board number or revision, so open the title block and compare it with the code printed on your motherboard before relying on it. Schematics like this let a technician trace power rails from the charger to the CPU regulators, check the EC and power button path, and locate parts on a shorted net. Any PDF viewer will open it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @jdbiosworld. Enginerys does not host this file.
