Summary

MacBook and MacBook Pro: Mac reduces processor speed when battery is removed while operating from an A/C adaptor

Products Affected

MacBook, MacBook Pro

If the battery is removed from a MacBook or MacBook Pro, the computer will automatically reduce the processor speed. This prevents the computer from shutting down if it demands more power than the A/C adaptor alone can provide.

Additional Information

Important: It is strongly recommended that you do not use your MacBook or MacBook Pro while the battery is removed. Accidently bumping the A/C adaptor could disconnect power and shutdown the computer. Any information that was not saved on your computer would be lost.
