: The laptop runs on battery but refuses to charge, or power drops immediately after hitting the power button.
Professional databases like Laptop-Schematics.com offer the boardview and schematic diagram for purchase.
Typically paired with Intel Core i5-8300H or i7-8750H CPUs.
Component-level motherboard repair requires precision, patience, and the right documentation. When troubleshooting the Compal LA-F952P Revision 1.0 motherboard—commonly found in popular mainstream laptops like the Lenovo IdeaPad 330-15IKB and 330-17IKB—having the schematic and boardview files is the difference between a successful repair and a scrapped board. la-f952p rev 1.0 boardview
Check the resistance to ground on the main current-sensing resistor ( PR801 or equivalent, check your schematic for exact numbering). A reading close to 0 Ohms indicates a short-circuit downstream on the +PWR_SRC rail. 2. Laptop Turns On but No Display (Black Screen)
: An open-source, multi-platform tool compatible with Windows, macOS, and Linux. It is favored for its fast performance and clean UI.
: Use the LA-F952P schematic to look up the power-up sequence and identify which voltage rails must turn on first. : The laptop runs on battery but refuses
On this board, the actual "power-on" signal is often linked through the keyboard controller rather than a simple physical switch. Tools to View the File To open an
Trace the power line from the input connector pads to the first and second protection MOSFETs.
If the meter beeps continuously (0.00 Ohms), you have a main rail short. A reading close to 0 Ohms indicates a
: It provides clear visibility for the 19V main power rail and gate signals for the input DC MOSFETs, allowing you to trace why a board might have a missing power rail even after replacing visible burned components.
: Hosts the Compal LA-F951P/LA-F952P power sequence and BOM details.
The is an indispensable diagnostic file used by component-level repair technicians to troubleshoot and fix hardware failures on the Acer Nitro 5 AN515-52 gaming laptop . Manufactured by Compal Electronics (under the internal codename DH5VF/DH53F), this motherboard hosts high-performance gaming hardware that is prone to common failures like short circuits, liquid damage, and power rail collapses.
