Schematic in PDF form for the GI5CPXX mainboard, with the name also carrying the model code T90-TB. Packed as a 2.19 MB RAR archive, it extracts to a PDF readable in any standard viewer. The circuit diagrams let a technician trace power rails and the power-on sequence, follow signals between the CPU, embedded controller and connectors, and look up component values for replacement parts. Confirm that the GI5CPXX marking and revision on the actual PCB match the drawings before relying on specific reference designators.
