If the cord is frayed or damaged, replace it. If the
terminals are soiled, wipe them with cotton or a
clean cloth.
If the AC adaptor still does not power the
computer, contact your dealer.
Problem Procedure

the computer
The battery may be discharged. Connect the AC
adaptor to charge the battery.

If the battery is completely discharged, it will not
begin charging immediately. Wait a few minutes.

outlet is supplying power. Test it by plugging in
an appliance. If it doesn’t work, try another
power source.
