  1. Disconnect all external peripherals.
  2. After charging for a while, if the battery does not seem to charge, or if it is fully charged but quickly discharges, verify with a known-good battery, and replace the faulty battery.

  4. If the sleep indicator light briefly illuminates just before the system shuts down, check the thermal sensor connection to the logic board. It should be fully seated with no damage to the wiring.
  5. Replace the logic board.
