Asus Vivo Book 14X X1403ZA Component Names and Test Points

Identify Asus Vivo Book 14X X1403ZA motherboard components, reference designators, and test points.

Motherboard Diagram and Circuit Information

The motherboard diagram illustrates the power distribution, with the EC releasing the power-good chain to bring up the 3V/5V always-on rails. The VRM generates VCCIN, which is then regulated by the PCH. The board brings up the rails in a specific order, with the EC releasing the power-good signal to enable the CPU.

Schematics File

The schematics file provides a comprehensive overview of the motherboard's circuitry, allowing technicians to plan and diagnose repairs. By tracing the power-on sequence from the adapter to the CPU, technicians can identify faulty components and plan component-level repairs using pinout and net data.

Follow the power-on sequence from the adapter to the CPU
Trace always-on rails, enable lines, and power-good signals
Identify the component behind a shorted or missing rail
Check EC, PCH, and clock connections against the design
Plan component-level repairs using pinout and net data

Boardview and Bitmap

The boardview and PCB layout files provide a visual representation of the motherboard's physical layout, allowing technicians to quickly locate components and trace nets. By cross-referencing the schematic with the physical layout, technicians can pinpoint faulty components and optimize repair procedures.

Find any component by reference designator in seconds
See which side of the board a part sits on
Trace a net to every pad it touches
Cross-reference the schematic with the physical layout

Common Faults on This Board

Common faults on this board include no power due to failed VRM or EC, no display due to failed eDP or LVDS transmission, and not charging due to faulty charging circuitry. Liquid damage can also cause the board to become dead, requiring thorough cleaning and component-level repair.

Why These Files Matter

Accurate repair data is crucial for laptop repair technicians, as it allows them to diagnose and repair faults quickly and efficiently. By using these files, technicians can avoid guesswork replacements and improve repair success rates, reducing the time and cost associated with repair.
