The top schematic has boxes with "SEE SHEET 2", "SEE SHEET 3". For example:
When analyzing the LA-D711P for repairs, focus on these critical measurement points: Target Voltage (Normal) CPU Core Rail Main Processor Power ~0.8V to 1.1V GFX Core Rail Integrated Graphics Power Memory Power BIOS Pin 8 BIOS Power Supply LA-D711P No Display | Laptop Repairing Full Course lad711p rev 10 schematic top
These are generated by the PWM controller (commonly a chip like the TPS51225 or similar). These rails must be present before the laptop can attempt to power on. The top schematic has boxes with "SEE SHEET
In the context of "Rev 10" repairs on this chassis, the "Top View" is the most critical part of the schematic document because it highlights where the solder joints fail. lad711p rev 10 schematic top
