The logic board of the MacBook Pro (16-inch, 2024), model A3403, 2024, 16-inch, M4 Pro (EMC 8895). Known faults are being collected.
No guided tree is live for this board yet. The profile, the viewer and manual entry are there on the free plan, and the first sessions on it build the tree.
Checked on 2026-10-29 against 2 sources: added. Two independent sources agree on the number with different revision suffixes: a Badcaps member posted "Model A3403 Board number 820-03396-05" in the A3401 schematic thread, and an eBay repair-service listing is titled "2024 APPLE MACBOOK 16 A3403 M4 PRO LAPTOP 820-03396-B LOGIC BOARD REPAIR SERVICE" (surfaced from the eBay category page listed; the item page itself was not captured). Neither page could be opened directly by the fetch tool (Badcaps renders empty, eBay returns 403), so both were read through search-result excerpts. A3403 = 16-inch M4 Pro, Mac16,7, EMC 8895 (everymac, Apple, ipc-computer). Whether the 16-inch M4 Max (A3186, Mac16,5) shares this board is unsourced. Badcaps members report no schematic or boardview exists for it yet. Revision A is a placeholder until Studio records the real revisions.
Open the board in NextProbe, answer the symptom questions and follow the lit point. The free plan includes three guided sessions a month. Your own boardview and schematic stay on your machine.
