MacBook charger not working

A charger that doesn't power the MacBook at all, as opposed to a battery that just won't hold charge, is usually a cable, adapter, or port issue that's simple to test.

Symptoms

  • No charging light or indicator appears when plugged in
  • Battery percentage doesn't move at all, even after a long time plugged in
  • Charger works with other devices but not the MacBook, or vice versa
  • Cable feels loose or doesn't click into place at the port

Likely causes

  • CommonA damaged or worn charging cableCables are the single most common point of failure in a charging setup.
  • CommonA faulty power adapter (the brick itself)Adapters can fail internally with no visible external sign.
  • CommonDebris in the charging port preventing a proper connectionLint and dust are especially common in USB-C ports carried in bags.
  • PossibleA non-Apple or non-certified charger not delivering proper powerCheap or incompatible third-party chargers can fail to charge reliably.
  • PossibleA charging circuit or battery fault inside the MacBookThis is more likely if a confirmed good cable, adapter, and clean port still don't work.

What to do

  1. Inspect the cable and adapter for visible damage, fraying, or bent connectors.
  2. Try a different known-good Apple or certified cable and adapter if available.
  3. Check the MacBook's charging port for lint or debris and gently clean it with a dry, soft brush.
  4. Plug directly into a wall outlet rather than a power strip, surge protector, or hub.
  5. Try the charger with a different compatible MacBook if you have access to one, to isolate whether it's the charger or the MacBook.
  6. Force restart the MacBook while connected to power to rule out a display/reporting glitch.
  7. Reset the SMC using the method appropriate for your Mac's chip type.
  8. If a confirmed good charger, cable, and clean port still show no charging at all, the MacBook likely has an internal charging circuit or battery issue needing professional repair.
