: Set your multimeter to continuity mode. Click the problematic power rail on the Boardview to see all connected capacitors. Test them one by one to find the shorted component.

The Compal LA-C701P (AAL10) is a widely used laptop motherboard found in several 15-inch Dell Inspiron and Vostro models, typically powered by Intel 5th Generation (Broadwell) processors. For component-level repair technicians, having access to the LA-C701P Rev 1.0 Boardview file and schematic diagram is the difference between a successful repair and a scrapped board.
For the LA-C701P, this file (often saved with extensions like .brd , .fz , or .cad ) is essential for tasks such as: : Set your multimeter to continuity mode

Often controlled by a Richtek IC to produce 3.3V3.3 cap V for the Super I/O and BIOS. TPS51225R (generates the 3
Subsequent voltage regulators turn on sequentially: Memory rail (+1.35VSP), PCH rails, and finally the CPU Core Voltage ( via PU701). 4. Common Failure Points on the LA-C701P Rev 1.0
The DC-in jack delivers 19V to the input MOSFETs (PQ101 and PQ102). These MOSFETs are controlled by the charging IC (often an ISL or BQ series controller, such as PU101). If these gates do not receive the proper turn-on voltage, the main system rail ( or B+ ) will remain at 0V. System Standby Rails (+3VALW / +5VALW)

A concrete LA-C701P Rev 1.0 boardview will show exact IC part numbers (e.g., PMIC model, EC model, BIOS flash ID), connector pinouts, and the silk-screened test points unique to that revision. Repair notes often accompany these boardviews: voltage expectations at TP pads, commonly failed components, and hot-swap places for known weak parts. For any technician, correlating symptom patterns with the boardview’s labeled rails and test points shortens time-to-fix dramatically.
