The Charging IC (often an Intersil/Renesas ISL series or Texas Instruments BQ series) must sense the correct adapter voltage on its ACIN / ACDET pin to turn on the gates of these isolation MOSFETs.

When power rails are present but the laptop displays a "No Post" condition (black screen, spinning fan), the issue usually relates to timing, clocks, or reset signals.
Typically integrates Intel Core i3-6100U , i5-6200U , or i7-6500U . Memory: Utilizes DDR3L RAM (Low Voltage). Typically integrates Intel Core i3-6100U , i5-6200U ,
The is more than a PDF—it is a repair roadmap. Without it, you are guessing component values, misdiagnosing pulse-skipping as a PWM failure, and potentially creating a fire hazard by replacing the wrong current-sense resistor.

: Intel Core i3-6100U, i5-6200U, and i7-6500U (Skylake architecture). Memory Type 0;494;: DDR3L (Low voltage).
Because many Compal motherboards do not print component labels (like PC102, PR45) directly on the physical green silkscreen, pairing your schematic with a .BDV or .CAD Boardview file is highly recommended to pinpoint physical component locations.
