Chapter 4
Mobile Computing
This chapter covers all aspects of using your computer while 
traveling.
Toshiba’s energy-saver design
Your computer enters a low-power standby mode when it is 
not being used, thereby conserving energy and saving money 
in the process. It has a number of other features that enhance 
its energy efficiency.
Many of these energy-saving features have been set by 
Toshiba. We recommend you leave these features active, 
allowing your computer to operate at its maximum energy 
efficiency, so that you can use it for longer periods while 
traveling.

Running the computer on battery power
5.375 x 8.375 ver 2.3
Running the computer on battery power
The computer contains a removable Lithium Ion (Li-Ion) 
high-capacity battery that provides power when you are away 
from an AC outlet. You can recharge it many times. 
Battery Notice
Battery life may vary depending on applications, power 
management settings and features utilized. Recharge time varies 
depending on usage. The battery may not charge while the 
computer is consuming full power. 
After a period of time, the battery will lose its ability to 
perform at maximum capacity and will need to be replaced. 
This is normal for all batteries. To purchase a new battery 
pack, see your accessories information that shipped with your 
computer, or visit the Toshiba Web site at: toshiba.com.
To ensure that the battery maintains its maximum capacity, 
operate the computer on battery power at least once a month 
until the battery is fully discharged. Please see “Maximizing 
battery life” on page 107 for procedures. If the computer is 
continuously operated on AC power, either through an AC 
adapter or a docking station (if applicable to your system), for 
an extended period (more than a month) the battery may fail 
to retain a charge. This may shorten the life of the battery, and 
the battery light may not indicate a low-battery condition.
In addition, the computer has an internal real-time clock 
(RTC) battery. The RTC battery powers the RTC memory, 
which stores your system configuration settings and the 
current time and date for up to a month while the computer is 
turned off. 
NOTE: For optimum DVD performance, Toshiba recommends that 
you play DVDs while running on AC power rather than on battery 
power.

Charging the battery

Power management
Your computer ships with the power management options 
preset to a configuration that will provide the most stable 
operating environment and optimum system performance for 
both AC power and battery modes. 
CAUTION: 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 system 
should use the preset configuration. For assistance with setup 
changes, contact Toshiba’s InTouch Center. 
Charging the battery
NOTE: Battery charge time may vary depending on the 
applications, power management settings, and features used.
The battery needs to be charged before you can use it to 
power the computer.
To charge the battery, plug the computer into a live wall 
outlet. It takes several hours to charge the battery with the 
computer off. It takes much longer to charge the battery while 
the computer is on. 
TECHNICAL NOTE: The battery does not charge while the 
computer is consuming full power.
The battery may not start charging immediately if:
❖The battery is extremely hot or cold.

Mobile Computing
Charging the battery
5.375 x 8.375 ver 2.3
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.
Charging the RTC battery
The computer contains an internal battery that provides 
power for the real-time clock (RTC) and calendar.
During normal use, the main battery keeps the RTC battery 
adequately charged. Occasionally, the RTC battery may lose 
its charge completely, especially if you have had the 
computer turned off for a long time. 
If the RTC battery is low, the real-time clock and calendar 
may display the incorrect time and date, or stop working.
To recharge the RTC battery, plug in the computer and leave 
it turned off for at least 24 hours.
NOTE: When Hibernate mode is enabled and the RTC battery is 
completely discharged, a warning prompts you to reset the real-
time clock.
