Schematic vs boardview: what you need for repair

If you're new to board-level repair, the two file types can be confusing. In short: the schematic tells you how the circuit works, the boardview tells you where things are.

Schematic

A schematic is a set of PDF pages drawn by the board designer. It shows every component with its reference (PU1, PQ12, PC305), its value, and how it connects. It also contains the power map and the power-on sequence — the most useful pages when a laptop doesn't turn on. You'll use it to answer questions like “which chip makes the 3.3 V always-on rail?” or “what enables the CPU core voltage?”.

Boardview

A boardview is the physical layout: component outlines, pins and test points, with net names. Click a net and every point on it lights up. It answers “where is PU1 on this board?” and “where can I measure this rail?”. Without it you'd be searching tiny labels with a microscope.

Using both

1. Find the failing stage in the schematic (for example: no 5 V always-on rail).
2. Note the part and net names (PU3, +5VALW).
3. Search those names in the boardview to locate them and the nearest test points.
4. Measure, compare with expected values, replace the faulty part.

That's why most file pages here show both types for the same board when available. Look for the Schematic and Boardview labels, and check which program opens your boardview.
