Connecting the AC adaptor
Attach the AC adaptor when you need to charge the battery or you want to
operate from AC power. It is also the fastest way to get started, because
the battery pack will need to be charged before you can operate from
battery power.
The AC adaptor can automatically adjust to any voltage ranging from 100 to
240 volts and to a frequency of either 50 or 60 hertz, enabling you to use
this computer in almost all country/region. The adaptor converts AC power
to DC power and reduces the voltage supplied to this computer.
■ Always use the TOSHIBA AC adaptor that was included with your
computer, or use AC adaptors specified by TOSHIBA to avoid any risk
of fire or other damage to the computer. Use of an incompatible AC
adaptor could cause fire or damage to the computer possibly resulting
in serious injury. TOSHIBA assumes no liability for any damage caused
by use of an incompatible adaptor.
■ Never plug the AC adaptor into a power source that does not
correspond to both the voltage and the frequency specified on the
regulatory label of the unit. Failure to do so could result in a fire or
electric shock, possibly resulting in serious injury.
■ Always use or purchase power cables that comply with the legal voltage
and frequency specifications and requirements in the country of use.
Failure to do so could result in a fire or electric shock, possibly resulting
in serious injury.
■ The supplied power cord conforms to safety rules and regulations in the
region the product is bought and should not be used outside this region.
For use in other regions, please buy power cords that conform to safety
rules and regulations in the particular region.
■ Do not use a 3-pin to 2-pin conversion plug.
■ When you connect the AC adaptor to the computer, always follow the
steps in the exact order as described in the User’s Manual. Connecting
the power cable to a live electrical outlet should be the last step
otherwise the adaptor DC output plug could hold an electrical charge
and cause an electrical shock or minor bodily injury when touched. As a
general safety precaution, avoid touching any metal parts.
■ Never place your computer or AC adaptor on a wooden surface,
furniture, or any other surface that could be marred by exposure to heat
since the computer base and AC adaptor's surface increase in
temperature during normal use.
■ Always place your computer or AC adaptor on a flat and hard surface
that is resistant to heat damage.
