The identifier YA4A1-94V-0 is not a specific motherboard model, but rather a generic manufacturing code often used by TMT and other PCB manufacturers to denote a motherboard's flammability rating (UL 94V-0) and base PCB design. This particular board is most commonly found in older laptops like the Acer Aspire P3, Compaq Armada M700, and specialized aviation systems from the mid-2000s. Understanding the YA4A1-94V-0 Motherboard Layout
Because this code refers to a multilayer test platform used by various brands, the "top" schematic layout typically follows a standard OEM-grade reference design for Intel-based systems of its era. 1. Central Processing Unit (CPU) & Socket Location: Center-top of the board.
Configuration: Typically supports Pentium 4 (Northwood) or early Core i5 mobile variants (e.g., i5-6300U) depending on the specific device iteration.
Function: Connects to the main power rails and manages instructions via the system bus. 2. Memory Architecture (RAM Slots) Location: Usually adjacent to the CPU socket.
Specs: Commonly features two slots supporting DDR or DDR2 modules (e.g., 400MHz CL=3).
Tip: If you cannot find the exact schematic, the true model number is often hidden on a white sticker near the RAM slots or under a processor label. Купить motherboard ya 4a1 94v 0 e114139 - Sendle.ru
YA-4A 1-94V-0 (also labeled ) is a specific motherboard part identifier primarily used for the ASUS X200MA

Since I cannot physically see the schematic file you are looking at, I have constructed a technical review based on the standard architecture and known components of the YA4A194V0 motherboard (commonly found in Lenovo ThinkPad E14 Gen 2 / E15 Gen 2 AMD models).
Here is a "good review" breakdown of the schematic from an engineering and repair perspective.
A typical YA4A194V0 top schematic is divided into several "blocks." Here is what you will find on the primary sheet (Page 1 of the PDF, usually labeled "TOP").
Located near the top-right edge of the schematic, this is the most complex section.
The YA-4A 1 94V-0 motherboard, also identified by part numbers such as TMT YA-4A1 94V-0 E114139, is a specialized multilayer printed circuit board (PCB) predominantly utilized in compact computing devices and diagnostic platforms. While it is most frequently associated with the Acer Aspire P3 touchscreen logic board, versions of this board are also found in Asus X551 series laptops and as a high-performance test platform for legacy Intel-based systems.

YA4A194V-0 (often identified as E114139) is a standard UL-certified marking for a Printed Circuit Board (PCB) manufactured by Ya-Hsin Industrial Co. Ltd.
This marking refers to the raw board's safety and flame-retardant standards (UL 94V-0) rather than a specific motherboard model name or schematic layout. The ya4a194v0 motherboard schematic top is more than
To generate a precise report or find the correct schematic, you will need to locate the manufacturer's specific model number, which is usually printed elsewhere on the board. Common examples of motherboards that use this PCB include models from: (e.g., MS-XXXX series) (Vaio laptop boards) How to Find the Correct Schematic Check for "MS-XXXX"
: Look for a four-digit number following "MS-" near the RAM slots or between the PCI-e slots. Look for Laptop Model Numbers
: If this is a laptop board, search for the laptop's model (e.g., Sony Vaio VGN-NW series) + "schematic." Search by "MB" or "P/N"
: Look for a Part Number (P/N) or Motherboard (MB) code like If you can provide the brand and model number of the computer or the specific
code printed on the PCB, I can help you find the detailed component breakdown or top-view diagram for that specific hardware.
To identify a motherboard using the code YA4A 194V-0, it is important to note that "94V-0" is a standard UL flammability rating for the PCB material, not a model number. This code is commonly found on various generic or OEM motherboards, including those used in specific aviation avionics systems. How to Identify Your Actual Motherboard Model
To find the specific schematic or manual for your board, you need the Manufacturer and Product Name, which can be found using the following methods: Software Methods (Windows):
System Information: Press Win + R, type msinfo32, and look for BaseBoard Manufacturer and BaseBoard Product.
Command Prompt: Run the command wmic baseboard get product,manufacturer,version,serialnumber to get a direct readout of the model.
Third-Party Tools: Use utility software like CPU-Z to view the motherboard details under the "Mainboard" tab. Physical Inspection:
Look for a printed model name on the PCB, often located between the PCI slots or near the RAM.
Check for a Revision (REV) number, as different versions of the same board may require different schematics. Finding Motherboard Schematics Once you have the specific model number (e.g., " Gigabyte B450M DS3H " or " Dell XPS 8700 "), you can search for technical documentation:
