Boardview for motherboard 11288-1 in a 152 KB RAR archive, marked BDV. The number matches the Wistron numbering scheme used across notebook boards built for several brands, and the name gives no model. Extract and open it in a boardview program to search reference designators, highlight a net across the board and locate test pads when tracing a short or a missing voltage. Confirm the PCB number and revision first, because layouts differ even between closely numbered boards.
