open on a second monitor, its "Top" page displaying the complex power rail architecture like a city map drawn in neon lines. He knew the 19V main rail was entering the board, but somewhere between the DC-in jack and the CPU, the lifeblood of the machine was vanishing. lac781p schematic top

Located near the DC-in jack, this area features the bq24725A (often marked as BQ25A ) charging IC. It manages the initial 19V rail (B+) and controls the N-channel MOSFETs that gate power to the rest of the system. lac781p schematic top
