Use the Boardview file in conjunction with the schematic. While the schematic tells you how it's connected, the boardview tells you where the component is physically located. 📥 Where to Find the Schematic
When troubleshooting this board, the schematic helps you navigate several critical "power rails" and logic circuits. 1. The Power Input Circuit (DC-IN)
The schematic includes a chart. This is a "map" showing the order in which voltages must appear. If the laptop turns on for 3 seconds and dies, use this chart to find which "S-state" is failing. 💡 Pro Repair Tips for LA-9413P la-9413p rev 1.0 schematic

This board uses two SPI Flash chips (UH2 and UH6). If power rails are present but there is no display, a BIOS re-flash is often required. Use the Boardview file in conjunction with the schematic
The LA-9413P Rev 1.0 is a Compal-designed motherboard. It typically houses 4th Generation Intel Core processors (Haswell architecture). Intel Shark Bay PCH: Lynx Point-LP Memory: DDR3L (Low Voltage)
🚩 Motherboard repair requires a multimeter, a DC power supply, and soldering skills. Never probe the board while the battery is connected. To help you further with your repair, could you tell me: If the laptop turns on for 3 seconds
Shorted ceramic capacitors on the +1.35V_MEM rail are frequent on this model, causing "no power" or "intermittent freezing."
The "Always-On" rails are managed by a PWM controller (often a TPS series chip). The schematic will label these as and +5VALWP . Without these, the power button will never trigger the boot sequence. 3. The Charging Circuit
