Lae801p Rev 20 Schematic Better (4K)

With steady hands, Elias began to work. He didn't just follow the lines; he felt them. He replaced a blown MOSFET, rerouted a signal line that the previous engineers had botched, and soldered a tiny jumper wire between the 3V-always rail and the hidden wake-up pin. "Ready?" Elias asked, more to the board than to Kael.

Phase margin improves from 45° to 68° typical, eliminating output ringing during load steps.

Check 19V at the drain of PQA1. A common issue is a shorted PQA1 (often PE642DT), causing the 19V rail to shut down. 3.3V/5V Standby Rails: Verify presence of +3V_LA_PCU and +5V_LA_PCU. Resistance Check:
