(also known by its project code ) is a motherboard manufactured by Compal for the Acer Nitro 5 (AN515-52/AN515-53) Acer Predator series laptops. Using the schematic and boardview is essential for diagnosing "dead" boards, which often stem from faults in the 19V input or charging circuits. 1. Board Specifications & Key Components Knowing the primary chips on this board helps you navigate the schematic pages quickly: Processor: Supports Intel 8th Gen Coffee Lake-H (e.g., Features NVIDIA GeForce GTX 1050 Ti (N17P-G0 GPU). Embedded Controller (EC/SIO): ENE KB9022 Intel HM370 (SR40B). Two slots for Laptopserviz 2. Common Troubleshooting Points Repair guides for this specific board often highlight these critical areas: The "Dead Board" Case Study: A common failure on the LA-F952P is a damaged Charging IC , which prevents the device from booting entirely. 19V Rail Inspection: 90% of power issues originate here. Check the two input MOSFETs (acting as switches) and the current sensor. If 19V is at the first MOSFET but not the second, check the gate voltage driven by the (Power Management) chip. Power Rails: Ensure you have the standard standby voltages: BIOS/EC Reset: If the laptop has a built-in battery and won't respond to the power button, try disconnecting the main and CMOS batteries and shorting the CMOS pins to reset a frozen EC or BIOS. 3. Essential Files for Repair To perform a complete repair, you typically need a package containing: Schematic Diagram: A searchable PDF for tracing circuit connections. BoardView (.brd): Used with software to physically locate components on the PCB. BIOS & EC Dumps: Binary files (.bin) for reflashing the main BIOS or the SIO chip if firmware corruption is suspected.
