Check the connections to make sure that the power cord/adaptor is firmly connected to the computer and a working power outlet.

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.

If the AC adaptor still does not power the computer, you should contact your reseller, dealer or service provider.
