A (typically in .bdv , .brd , or .cad formats) is a 2D or 3D interactive map of the printed circuit board (PCB). Unlike a standard schematic, which only shows how components connect logically, a boardview shows exactly where those components are physically located on the top and bottom layers of the board. Boardview files usually come in specialized formats such as

The power adapter light turns off or blinks the moment it is plugged into the laptop (indicating the adapter’s internal short-circuit protection has tripped).

If the battery doesn't charge or the laptop dies instantly when the charger is removed, this area is the first place to look.
