Hardware and system checklist
Procedure
The battery may be discharged. Connect the AC
power cord to charge the battery.
If the battery is completely discharged, it will not
begin charging at once. Wait a few minutes.
If the battery still does not charge, make sure the
outlet 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. 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.
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 for 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.
Check the power consumption settings in the
TOSHIBA Power Management Utility. Consider
using a power saving mode.
