Quanta G38D boardview for an HP laptop, matching the Quanta board number DAG38DMBCC0, in .brd format at about 452 KB. Quanta codes start with DA followed by the project name, here G38D, and that string should be printed on the motherboard you have. The layout opens in boardview programs such as OpenBoardView or FlexBV, letting a technician search parts by designator, follow nets and find test points while diagnosing power rails, charging circuits or shorts. No HP model name appears in the file name, so identify the board by its code.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardviews. Enginerys does not host this file.
How to open a .brd file
The most common boardview extension. Several unrelated formats share it, which is why one viewer opens a .brd and another refuses it.
