Schematic for the Sony PCG-FR825CP notebook, based on a Quanta RB1 board design at revision 1A. Quanta identifies its projects with short codes such as RB1, typically appearing in the DA-numbered label on the mainboard. This 874 KB PDF is used to follow DC-in and charging circuits, core voltage regulators and signal routing, and to pinpoint components feeding a dead or shorted rail. Compare the project code and revision on your board with the document before relying on it for repairs.
