You may want to trade in your Nokia charger for a new one. Nokia is recommends you exchange chargers made by one of their vendors for
free replacements.
During a routine quality control process,
Nokia identified a potential product quality issue. The plastic
covers of the affected chargers could come loose and separate, exposing
the charger's internal components and potentially posing an electrical
shock hazard if certain internal components are touched while the
charger is plugged into a live socket. Nokia is not aware of any
incidents or injuries related to these chargers.
The models that should repalced are the AC-3E and AC-3U models,
manufactured between June 15, 2009 and August 9, 2009; and the AC-4U
model, manufactured between April 13, 2009 and October 25, 2009.
For
more information, including how consumers can check to see if their
chargers are part of this exchange program, Nokia has established a
website. Consumers are asked to visit http://chargerexchange.nokia.com
or their local Nokia website.
Nokia recommends consumers with
chargers within the scope of this exchange program to stop using the
charger and exchange it for a free replacement.
