MACBOOK AIR M2 Overheating Shutdown

Logic Board Assembly

The M2 Air utilizes integrated thermal sensors and a PMIC to monitor heat; since the device is fanless, any hard shutdown that occurs despite software throttling suggests a malfunction in the logic board's ability to regulate voltage or interpret sensor data. As the CPU and thermal controllers are non-serviceable sub-components, the entire board must be replaced to resolve hardware-level thermal instability.

Diagnostic code PPP001, specifically reported in the search data regarding M2 Air overheating, refers to a potential fault in the power supply or power delivery system. A defective or non-genuine charger can cause excessive heat at the charging port and PMIC during high-current draw, leading to a thermal safety shutdown.

Internal Heat Spreader/Thermal Interface Material

While the M2 Air lacks a traditional fan, it uses a metal heat spreader to transfer heat from the M2 chip to the chassis. If there is a void or improper contact in the factory-applied thermal interface material (TIM), the chip will heat up faster than the chassis can dissipate it, causing sudden shutdowns during intensive tasks.
