Boardview file for the Apple MacBook A1181 logic board 820-2279, revision A, supplied as a 157 KB RAR in BDV form. Apple marks its logic boards with 820-xxxx numbers, and the trailing letter shows the revision. A boardview lets you search for parts by reference designator, highlight nets and find test points when tracing a short on a power rail or a missing standby voltage. Open it in a viewer that supports BDV, and check the 820 number printed on the board before trusting locations.
