La-9413p Rev 1.0 Schematic ((free)) 〈VERIFIED〉

Once the power button is pressed, the EC sends out enable signals ( SUSP# ) to close transfer switches (MOSFETs) that convert the Always-On ( ALW ) voltages into Switchable ( S or VS ) voltages. This powers the RAM (+1.35V), PCH core (+1.05V), and peripheral ICs. 4. CPU Core Voltage (+VCC_CORE)

This usually runs alongside the 3.3V line and powers secondary wake systems and USB power states.

NBSWON# (Pin 114): Power button trigger signal. It should drop from 3.3V to 0V when the button is pressed. EC_RST# : Reset signal for the controller. ACIN : Tells the EC that an official charger is connected. la-9413p rev 1.0 schematic

ENE KB9012QF A4. This chip manages the power sequence, keyboard, touchpad, battery charging communication, and thermal monitoring. 2. Power Rail Architecture and Power Sequence

The LA-9413P Rev 1.0 is a motherboard designed by for Dell. It was used primarily in two laptop models:

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 Once the power button is pressed, the EC

The is more than a wiring diagram—it is a logical map of a complex computing machine. Whether you are repairing a dead short on a Compaq CQ45 or diagnosing a missing GPU voltage on an HP Pavilion G6, this document is your most valuable asset.

Trace the DC-in jack to the entry protection MOSFETs (often labeled PQ301 and PQ302). Check if 19V passes through to the main current-sensing resistor (PR302). If stuck at the first MOSFET, check the charging IC (ISL88731C or similar) ACIN/ACOK signals. CPU Core Voltage (+VCC_CORE) This usually runs alongside

This motherboard has several known failure points often discussed in repair forums:

Ultimate Guide to the Compal LA-9413P Rev 1.0 Schematic The Compal LA-9413P (often labeled as V5WE2) is a widely used laptop motherboard found across several Acer Aspire models, including the E1-570, E1-572, E1-532, and V5-572 series. Whether you are a professional microsoldering technician or a DIY repair enthusiast, having and understanding the schematic diagram for this specific board revision (Rev 1.0) is essential for diagnosing power issues, component failures, and no-display symptoms.
