MacBook Pro 14-inch 2021 (A2442)A2442

Details

The 2021 14-inch MacBook Pro uses more than one Apple power chip around its processor. This listing covers the 440-pin 343S00515, one of the larger ones, which is worth checking when the laptop shows no life on a known-good charger.

It's listed for the MacBook Pro 14-inch A2442 from Late 2021. The store also lists a smaller 56-pin power IC, 338S00600, for the same model. Neither listing gives a board position or says which rails the chip controls.

Reasons to replace it

No power-on with a good charger.
Low, stuck current with missing rails.
A short traced to this chip.
Liquid damage under the chip.

Approach

Clear any shorted capacitors first, as they're the usual cause of missing rails on Apple silicon boards. Then confirm the chip's inputs and outputs, and use a preheater and careful underfill removal for the 440-pin BGA.

After fitting, check the rails and test boot, MagSafe and USB-C charging, and the display before closing the case. A short load test afterward confirms the rails stay steady.
