Q: MacBook Pro will not charge

Make an appointment at the Apple Genius Bar for service. If needed find an Apple Store - Find a Store - Apple. The problem may be more than the battery. They can run a diagnosis of the problem which is usually free.

Given the total cycles of the battery indicate it has reached the higher end of usage

a new battery is a likely recourse and would be a possible solution. If the MagSafe

adapter port in the computer is clean and the connectors appear to be able to touch

fully on both sides (adapter and port in macbook) then consider a Genius appointment.

There may be a problem with the circuitry inside the port of the MacBook Pro, if that

is so, the computer may need replacement DC-in Board. First, the battery cycles of

use indicate that to be a likely suspect in this round. Inspect the MagSafe contacts.
