Check the connections to make sure that the

Check the condition of the cord and terminals. If 
the cord is frayed or damaged it should be 
replaced, while if the terminals are soiled, they 
should be cleaned with a clean cotton cloth.

computer, you should contact your reseller, 
dealer or service provider.
