User's Manual
Procedure
Check the connections. Make sure the cord is
firmly connected to the computer and a power
outlet.
Check the condition of the cord and terminals.
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.
Procedure
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.
If the battery still does not charge, make sure the
outlet of the AC adaptor is supplying power.
Plug in an appliance and see if it works. If it
doesn't, try another power source.
Check whether the battery is hot or cold to the
touch. If the battery is too hot or too cold, it will not
charge properly. Let it reach room temperature.
Unplug the AC adaptor and remove the battery to
make sure the terminals are clean. If necessary
wipe them with a soft dry cloth dipped in alcohol.
Connect the AC adaptor and replace the battery.
Make sure it is securely seated.
Check the Battery indicator. If it does not glow,
let the computer charge the battery for at least 20
minutes. If the Battery indicator glows after 20
minutes, let the battery continue to charge at
least another 20 minutes before turning on the
computer.
If the indicator still does not glow, the battery may
be at the end of its operating life. Replace it.
If you do not think the battery is at the end of its
operating life, see your dealer.
