Mobile Computing
Running the computer on battery power
To ensure that the battery maintains its maximum capacity,
operate the computer on battery power at least once a month. The
Lithium-Ion battery has no memory effect so it is not necessary to
let the battery fully discharge each time. However, for better
accuracy of the battery meter, it is helpful to fully discharge the
battery periodically. Please see “Maintaining your battery” on
page 131 for procedures. If the computer is continuously operated
on AC power, either through an AC adaptor or a port replicator (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 may cause the battery meter to be inaccurate.
For optimum optical media performance, it is recommended that you
play DVDs while running the computer on AC power. For more
information about Windows
®
power plans, see “Power Plans” on
page 125.
The computer also has an internal real-time-clock (RTC) battery.
The RTC battery powers the RTC memory that stores your system
configuration settings and the current time and date information. It
maintains this information for up to a month while the computer is
turned off.
TECHNICAL NOTE: Depending on your system, the RTC battery may
only charge while the computer is turned on.
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.
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
Customer Support Center.
