Procedure
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.

The battery may be discharged - connect the AC
adaptor to recharge the battery.
