The 2021 schematic introduces a soft-start sequence for the Embedded Controller (EC) that lasts 180ms—longer than the 80ms standard from 2019. Why? A firmware patch. The EC was booting too fast for the retimer chip, causing PCIe link failures. If you're probing this board, don't panic if +3VALW takes a third of a second to appear. That delay is intentional .
