Charging batteries
Changes to these settings may result in system performance or
stability issues. Users who are not completely familiar with the power
management component of the computer should use the preset
configuration. For assistance with setup changes, contact Toshiba’s
Customer Support Center.
Charging batteries
The battery needs to be charged before you can use it to power the
computer.
Always use the AC adaptor specified by Toshiba. You can
order a Toshiba AC adaptor from Toshiba’s Web site at
accessories.toshiba.com.
Charging the main battery
To charge the main battery, plug the computer into a live electrical
outlet. The battery charges whether the computer is on or off.
TECHNICAL NOTE: The recharging of the battery cannot occur when
your computer is using all of the power provided by the AC adaptor to
run applications, features, and devices. Your computer's Power Options
utility can be used to select a power level setting that reduces the power
required for system operation and will allow the battery to recharge.
The battery may not start charging immediately under the following
conditions:
❖ The battery is extremely hot or cold.
To ensure that the battery charges to its full capacity, wait until
it reaches room temperature (50 to 80 degrees Fahrenheit, 10 to
26 degrees Celsius).
❖ The battery is almost completely discharged.
Leave the power connected and the battery should begin
charging after a few minutes.
HINT: Once the battery is fully charged, we recommend that you
operate your computer on battery power until the battery discharges
completely. Doing this extends battery life and helps ensure accurate
monitoring of battery capacity.
