About the Dell Precision library

113 Dell Precision files from public repair archives: 87 BIOS dumps, 13 schematics, 12 boardviews and 1 other files. By device: laptops 104, graphics cards 7 and desktop boards 2.

Finding the board number. Dell boards are usually marked with a Compal LA- number (LA-K411P) or a five-digit Wistron number such as 19746-1, followed by a revision like A00.

Titles are cleaned-up filenames; hover a title to see the original. Brand, series, board number and file type are detected automatically, so compare the board number and revision before you flash a dump or rely on a diagram.
