MacBook Repair Electronics Glossary

If you’re involved in MacBook repair, understanding key electronics terms is essential. This glossary covers important components like transistors, fuses, MOSFETs, inductors, and more to help you diagnose and fix issues quickly and accurately.

When repairing MacBooks, components such as the System Management Controller (SMC) play a vital role in power management. Knowing how to test elements like resistors, capacitors, and diodes can save time and improve repair quality. For example, a MOSFET controls power delivery on the logic board, and a shorted MOSFET could cause boot problems or overheating.

Other key parts include power rails that supply stable voltages to CPU and memory, as well as bulk capacitance that filters noise in the power supply. Proper understanding of these will help you troubleshoot complex MacBook problems more effectively.
