Completely discharging GaN brick capacitors, cleaning pogo pins with 99% IPA, and triggering PMU cold reset.

Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

  1. Unplug power brick from the wall and disconnect MagSafe cable. Wait 2 full minutes for capacitors to discharge.
  2. Clean the 5 gold spring-loaded pins with 99% isopropyl alcohol and a lint-free swab.
  3. Plug adapter directly to wall, connect MagSafe to Mac, and power on. The LED will illuminate steady amber.

Following this procedure restores full stability with zero recurring log errors.
