MagSafe adapter problems
Apple has admitted faults in some of the MagSafe power adapters bundled with MacBooks, according to support documents. The company says that insular material on the cable -- particularly near the magnetic connector -- can tear prematurely, exposing the underlying wire. Aside from representing a possible safety hazard, Apple notes that the cable can eventually become discolored, and that its molding may deform.
The company thus says that people should take affected adapters to an Apple Store or an official service provider, and ask for a new one; free replacements, however, are only being given to people whose adapters do not show "signs of abuse." Service at a Genius Bar may also require an advance appointment.
