MacBook Air A2337 M1 Not Charging Fix | Stuck on 5V & No Current

Did your M1 MacBook Air (A2337) suddenly stop charging and power off, stuck at 5V with no current draw? In this detailed repair video, we diagnose and fix a common, tricky charging fault on these boards. My diagnosis path: Symptoms: Laptop is dead, draws zero current from USB-C. USB voltage is stagnant at 5V, failing to negotiate to 20V. Initial Checks: Full board inspection, verified all USB-C port connectors are healthy. Measurement: Found a short circuit on a key 3.3V LDO power line around one of the two CD3217 ACE chips (Thunderbolt/USB controller). Confirmation: Injected 0.8V into the shorted LDO line and used a thermal camera to locate the exact failing component. The CD3217B12 chip lit up immediately. Repair: Swapped the failing CD3217B12 with a donor chip from a matching board. See the full process of microscopic soldering and verification of the fix, taking the voltage negotiation back to 20V and restoring charging and power functionality.
