MacBook Pro 14-inch M3 (A2918)A2918

Details

The base 14-inch MacBook Pro with the M3 chip arrived in late 2023. Like other Apple silicon laptops, it depends on a handful of Apple power chips around the processor, and one failing can leave the machine dead on the charger or stalled at a low current draw.

This listing sells the Apple 343S00637 power IC, a 420-pin BGA, for the MacBook Pro 14-inch A2918 (2023, M3). The listing calls it a MacBook 14 and doesn't give a board position or say which rails it handles.

When to suspect it

No power-on with a known-good charger.
Low, stuck current with missing rails.
A short traced to this chip.
Corrosion after liquid.

Practical approach

Look for shorted capacitors first, since they're the most common cause of missing rails on these boards. Then confirm the chip's inputs and outputs before replacing a 420-pin BGA, which needs a preheater and careful pad preparation.

After fitting, check the rails and test boot, charging and the display before closing the case. Run the machine under load for a while to confirm it stays stable.
