Laptop mainboard schematic for the T76J, delivered as a comparatively large 4.23 MB PDF. No board number, revision or manufacturer appears in the file name, so confirm the version from the title block and from the markings on the PCB itself. A repair technician uses this drawing to follow rails from the adapter input through the charger and DC-DC converters, verify enable signals, and identify capacitors or ICs connected to a short-circuited net. A searchable PDF reader lets you jump to net names and component references.
