Compact PDF schematic of about 41 KB for the power daughterboard of the X63C project, a Quanta code linked in this set to the HP ProBook 450 G3; no revision appears in the name. A power board normally hosts the power button and sometimes status LEDs, so the sheet lets you check switch continuity, pull-ups and the cable pinout leading to the EC on the main board when a unit will not turn on. Match the printed part number on the small PCB before relying on 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 @LaptopsBoardview. Enginerys does not host this file.
