PDF schematic for the Inventec-built motherboard 6050A2250301-MB-A03, compressed into a RAR archive of roughly 956 KB. The 6050A prefix followed by -MB- and a revision suffix is the numbering used by Inventec, whose boards appear in many Toshiba and HP notebooks. With the circuit diagram a technician can follow power rails through the PWM controllers, read signal paths between chips and identify component values around a failed section. Make sure the revision on the PCB is A03, since earlier revisions can differ in parts and nets.
